Quantum mechanics (QM -- also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at nanoscopic scales where the action is on the order of the Planck constant. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. Quantum mechanics provides a substantially useful framework for many features of the modern periodic table of elements including the behavior of atoms during chemical bonding and has played a significant role in the development of many modern technologies. In advanced topics of quantum mechanics, some of these behaviors are macroscopic (see macroscopic quantum phenomena) and emerge at only extreme (i.e., very low or very high) energies or temperatures (such as in the use of superconducting magnets). For example, the angular momentum of an electron bound to an atom or molecule is quantized. In contrast, the angular momentum of an unbound electron is not quantized. In the context of quantum mechanics, the wave--particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects. The mathematical formulations of quantum mechanics are abstract. A mathematical function, the wavefunction, provides information about the probability amplitude of position, momentum, and other physical properties of a particle. Mathematical manipulations of the wavefunction usually involve bra--ket notation which requires an understanding of complex numbers and linear functionals. The wavefunction formulation treats the particle as a quantum harmonic oscillator, and the mathematics is akin to that describing acoustic resonance. Many of the results of quantum mechanics are not easily visualized in terms of classical mechanics. For instance, in a quantum mechanical model the lowest energy state of a system, the ground state, is non-zero as opposed to a more "traditional" ground state with zero kinetic energy (all particles at rest). Instead of a traditional static, unchanging zero energy state, quantum mechanics allows for far more dynamic, chaotic possibilities, according to John Wheeler. The earliest versions of quantum mechanics were formulated in the first decade of the 20th century. About this time, the atomic theory and the corpuscular theory of light (as updated by Einstein) first came to be widely accepted as scientific fact; these latter theories can be viewed as quantum theories of matter and electromagnetic radiation, respectively. Early quantum theory was significantly reformulated in the mid-1920s by Werner Heisenberg, Max Born and Pascual Jordan, (matrix mechanics); Louis de Broglie and Erwin Schrödinger (wave mechanics); and Wolfgang Pauli and Satyendra Nath Bose (statistics of subatomic particles). Moreover, the Copenhagen interpretation of Niels Bohr became widely accepted. By 1930, quantum mechanics had been further unified and formalized by the work of David Hilbert, Paul Dirac and John von Neumann with a greater emphasis placed on measurement in quantum mechanics, the statistical nature of our knowledge of reality, and philosophical speculation about the role of the observer. Quantum mechanics has since permeated throughout many aspects of 20th-century physics and other disciplines including quantum chemistry, quantum electronics, quantum optics, and quantum information science. Much 19th-century physics has been re-evaluated as the "classical limit" of quantum mechanics and its more advanced developments in terms of quantum field theory, string theory, and speculative quantum gravity theories. https://www.youtube.com/watch?v=ZsVGut7G-dU quantum solace, quantum world, #quantum

The time scale of the universe is very long compared to that for human life. It was therefore not surprising that until recently, the universe was thought to be essentially static, and unchanging in time. On the other hand, it must have been obvious, that society is evolving in culture and technology. This indicates that the present phase of human history can not have been going for more than a few thousand years. Otherwise, we would be more advanced than we are. It was therefore natural to believe that the human race, and maybe the whole universe, had a beginning in the fairly recent past. However, many people were unhappy with the idea that the universe had a beginning, because it seemed to imply the existence of a supernatural being who created the universe. They preferred to believe that the universe, and the human race, had existed forever. Their explanation for human progress was that there had been periodic floods, or other natural disasters, which repeatedly set back the human race to a primitive state. This argument about whether or not the universe had a beginning, persisted into the 19th and 20th centuries. It was conducted mainly on the basis of theology and philosophy, with little consideration of observational evidence. This may have been reasonable, given the notoriously unreliable character of cosmological observations, until fairly recently. The cosmologist, Sir Arthur Eddington, once said, 'Don't worry if your theory doesn't agree with the observations, because they are probably wrong.' But if your theory disagrees with the Second Law of Thermodynamics, it is in bad trouble. In fact, the theory that the universe has existed forever is in serious difficulty with the Second Law of Thermodynamics. The Second Law, states that disorder always increases with time. Like the argument about human progress, it indicates that there must have been a beginning. Otherwise, the universe would be in a state of complete disorder by now, and everything would be at the same temperature. In an infinite and everlasting universe, every line of sight would end on the surface of a star. This would mean that the night sky would have been as bright as the surface of the Sun. The only way of avoiding this problem would be if, for some reason, the stars did not shine before a certain time. In a universe that was essentially static, there would not have been any dynamical reason, why the stars should have suddenly turned on, at some time. Any such "lighting up time" would have to be imposed by an intervention from outside the universe. The situation was different, however, when it was realised that the universe is not static, but expanding. Galaxies are moving steadily apart from each other. This means that they were closer together in the past. One can plot the separation of two galaxies, as a function of time. If there were no acceleration due to gravity, the graph would be a straight line. It would go down to zero separation, about twenty billion years ago. One would expect gravity, to cause the galaxies to accelerate towards each other. This will mean that the graph of the separation of two galaxies will bend downwards, below the straight line. So the time of zero separation, would have been less than twenty billion years ago. At this time, the Big Bang, all the matter in the universe, would have been on top of itself. The density would have been infinite. It would have been what is called, a singularity. At a singularity, all the laws of physics would have broken down. This means that the state of the universe, after the Big Bang, will not depend on anything that may have happened before, because the deterministic laws that govern the universe will break down in the Big Bang. The universe will evolve from the Big Bang, completely independently of what it was like before. Even the amount of matter in the universe, can be different to what it was before the Big Bang, as the Law of Conservation of Matter, will break down at the Big Bang. Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang. Events before the Big Bang, are simply not defined, because there's no way one could measure what happened at them. This kind of beginning to the universe, and of time itself, is very different to the beginnings that had been considered earlier. These had to be imposed on the universe by some external agency. There is no dynamical reason why the motion of bodies in the solar system can not be extrapolated back in time, far beyond four thousand and four BC, the date for the creation of the universe, according to the book of Genesis. Thus it would require the direct intervention of God, if the universe began at that date. By contrast, the Big Bang is a beginning that is required by the dynamical laws that govern the universe. It is therefore intrinsic to the universe, and is not imposed on it from outside.

Edward Snowden - Full Documentary 2016 Edward Snowden Documentary “I don't want to live in a society that does these sort of things ... I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under.” —Edward Snowden Synopsis Born in North Carolina in 1983, Edward Snowden later worked for the National Security Agency through subcontractor Booz Allen in the organization's Oahu office. During his time there, Snowden collected top-secret documents regarding NSA domestic surveillance practices that he found disturbing. After Snowden fled to Hong Kong, China and met with Guardian journalists, newspapers began printing the documents that he had leaked, many of them detailing the monitoring of American citizens. The U.S. has charged Snowden with violations of the Espionage Act while many groups call him a hero. Snowden has found asylum in Russia and continues to speak about his work. A documentary on his story, Citzenfour, won an Oscar in 2015, with a 2016 biopic also in the pipeline. Background and Early Years Edward Snowden was born in Elizabeth City, North Carolina, on June 21, 1983. His mother works for the federal court in Baltimore (the family moved to Maryland during Snowden's youth) as chief deputy clerk for administration and information technology. Snowden's father, a former Coast Guard officer, later relocated to Pennsylvania and remarried. Snowden dropped out of high school and studied computers at Anne Arundel Community College in Arnold, Maryland (from 1999 to 2001, and again from 2004 to 2005). Between his stints at community college, Snowden spent four months (May to September 2004) in the Army Reserves in special-forces training. He did not complete training according to Army sources, and he was discharged after he broke his legs in an accident.

WHAT IS THE VENUS PROJECT? http://www.advexon.com The Venus Project is an organization that proposes a feasible plan of action for social change, one that works towards a peaceful and sustainable global civilization. It outlines an alternative to strive toward where human rights are no longer paper proclamations but a way of life. We operate out of a 21.5-acre Research Center located in Venus, Florida. When one considers the enormity of the challenges facing society today, we can safely conclude that the time is long overdue for us to re-examine our values and to reflect upon and evaluate some of the underlying issues and assumptions we have as a society. This self-analysis calls into question the very nature of what it means to be human, what it means to be a member of a "civilization," and what choices we can make today to ensure a prosperous future for all the world's people. At present we are left with very few alternatives. The answers of yesterday are no longer relevant. Either we continue as we have been with our outmoded social customs and habits of thought, in which case our future will be threatened, or we can apply a more appropriate set of values that are relevant to an emergent society. Experience tells us that human behavior can be modified, either toward constructive or destructive activity. This is what The Venus Project is all about - directing our technology and resources toward the positive, for the maximum benefit of people and planet, and seeking out new ways of thinking and living that emphasize and celebrate the vast potential of the human spirit. We have the tools at hand to design and build a future that is worthy of the human potential. The Venus Project presents a bold, new direction for humanity that entails nothing less than the total redesign of our culture. What follows is not an attempt to predict what will be done, only what could be done. The responsibility for our future is in our hands, and depends on the decisions that we make today. The greatest resource that is available today is our own ingenuity. While social reformers and think tanks formulate strategies that treat only superficial symptoms, without touching the basic social operation, The Venus Project approaches these problems somewhat differently. We feel we cannot eliminate these problems within the framework of the present political and monetary establishment. It would take too many years to accomplish any significant change. Most likely they would be watered down and thinned out to such an extent that the changes would be indistinguishable. The Venus Project advocates an alternative vision for a sustainable new world civilization unlike any social system that has gone before. Although this description is highly condensed, it is based upon years of study and experimental research by many, many people from many scientific disciplines. We propose a fresh, holistic approach - one that is dedicated to human and environmental concerns. It is an attainable vision of a bright and better future, one that is appropriate to the times in which we live, and both practical and feasible for a positive future for all the world's people. The Venus Project calls for a straightforward approach to the redesign of a culture, in which the age-old inadequacies of war, poverty, hunger, debt, environmental degradation and unnecessary human suffering are viewed not only as avoidable, but totally unacceptable. One of the basic premises of The Venus Project is that we work towards having all of the Earth's resources as the common heritage of all the world's people. Anything less will simply result in a continuation of the same catalog of problems inherent in the present system. Throughout history, change has been slow. Successive groups of incompetent leaders have replaced those that preceded them, but the underlying social and economic problems remain because the basic value systems have gone unaltered. The problems we are faced with today cannot be solved politically or financially because they are highly technical in nature. There may not even be enough money available to pay for the required changes, but there are more than enough resources. This is why The Venus Project advocates the transition from a monetary-based society to the eventual realization of a resource-based global economy. We realize to make the transition from our present culture, which is politically incompetent, scarcity-oriented and obsolete, to this new, more humane society will require a quantum leap in both thought and action.

Measuring the Greatest Ocean Depth The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters. If Mount Everest, the highest mountain on Earth, were placed at this location it would be covered by over one mile of water. The first depth measurements in the Mariana Trench were made by the British survey ship HMS Challenger, which was used by the Royal Navy in 1875 to conduct research in the trench. The greatest depth that they recorded at that time was 8,184 meters (26,850 feet). In 1951, another Royal Navy vessel, also named the "HMS Challenger," returned to the area for additional measurements. They discovered an even deeper location with a depth of 10,900 meters (35,760 feet) determined by echo sounding. The Challenger Deep was named after the Royal Navy vessel that made these measurements. In 2009, sonar mapping done by researchers aboard the RV Kilo Moana, operated by the University of Hawaii, determined the depth to be 10,971 meters (35,994 feet) with a potential error of ± 22 meters. The most recent measurement, done in 2010, is the 10,994 meter ( ± 40 meter accuracy) depth reported at the top of this article, measured by the United States Center for Coastal & Ocean Mapping.

How Plants Communicate & Think - Nature Documentary HD You may not think of plants as particularly chatty or active organisms, but they’re not as passive as they might seem. Plants can’t run away, so they have to develop other strategies to stay alive, as James Cahill, an environmental plant ecologist at the University of Alberta, explains in “What Plants Talk About,” a documentary from the PBS show NATURE. They’ve evolved the use of chemicals to communicate with insects and each other in order to thrive. Here are five behaviors that show how active plants can be.

Check out our new channel with interesting facts: https://www.youtube.com/c/seosantv [Top Truths] If Alien exist where do they live and how do they live? Scientists say a world that's 490 light-years away qualifies as the first confirmed Earth-sized exoplanet that could sustain life as we know it — but in an environment like nothing we've ever seen. http://www.advexon.com The planet, known as Kepler-186f, is "more of an Earth cousin than an Earth twin," Elisa Quintana, an astronomer at the SETI Institute at NASA Ames Research Center, told the journal Science. Quintana is the lead author of a report on the planet published by Science this week. "This discovery does confirm that Earth-sized planets do exist in the habitable zones of other stars," Quintana said during a Thursday news briefing at NASA Headquarters. Kepler-186f goes around an M-type dwarf star that's smaller and cooler than our sun. But it orbits much closer to its parent star than Earth does, within what would be Mercury's orbit in our own solar system. Those two factors combine to produce an environment that could allow for liquid water on the surface, assuming that the planet had a heat-trapping atmosphere. "The star, to our eyes, would look slightly orange-y," about a third again as big as our sun but only a third as bright, said co-author Thomas Barclay, a staff scientist for NASA's Kepler mission who is also affiliated with NASA and the Bay Area Environmental Research Institute. At midday, Kepler-186f's landscape might look similar to what we see on Earth an hour before sunset, he told NBC News. Or it might not: If the planet lacked an atmosphere to retain and redistribute its sun's warmth, it would be a cold, dry, lifeless world. Kepler-186f probably rates as the most potentially Earthlike planet discovered so far, said Jim Kasting, a geoscientist at Penn State University who did not play a role in the Science study. But he told NBC News that it's still "less likely to be habitable than planets around more sunlike stars." Even better prospects for alien habitability might well be identified in the months and years to come. How the world was found Kepler-186f is just the latest discovery to be pulled out of terabytes' worth of data collected by the Kepler mission. Before it went on the fritz last year, the Kepler space telescope stared at more than 150,000 stars in a patch of sky, looking for the telltale dimming of starlight as planets passed over the stars' disks. Nearly 1,000 exoplanets have been confirmed using Kepler data, and almost 3,000 more candidates are still awaiting confirmation. It takes years of observation to confirm the pattern of dimming and brightening that's associated with alien planets, particularly if the planets are small and far from their parent stars. In February, astronomers reported that at least four worlds circled the dwarf star known as Kepler-186 or KOI-571. In this week's Science paper, Quintana and her colleagues confirm the existence of Kepler-186f as the fifth and outermost world. They report that Kepler-186f is about 10 percent wider than Earth, tracing a 130-day orbit around its sun at a mean distance of 0.35 astronomical units. (An astronomical unit is the distance between Earth and our sun, which is 93 million miles or 150 million kilometers.) That would put Kepler-186f on the cooler, outer side of the star's habitable zone — the range of orbital distances where liquid water could exist on a planet's surface. Astronomers have confirmed the existence of other planets in their stars' habitable zone, but those prospects are super-Earth-size. Smaller habitable-zone candidates also have been found, but they have yet to be confirmed as planets. Barclay said Kepler-186f was particularly promising because it's less than 1.5 times the size of Earth. Planets in that size range are more likely to be rocky with a thinner atmosphere, like Earth, Mars and Venus. But worlds exceeding that size stand a better chance of retaining a thick atmosphere of hydrogen and helium, like the giant planet Neptune. "While those planets also could be rocky, they don't remind us of home," Barclay said. Could we actually detect signs of life on Kepler-186f? That's a tough one. The astronomers behind the discovery acknowledge that the planet might be just too far away for follow-up studies. The SETI Institute has been searching for radio signals from the Kepler-186 system over a wide frequency range (1 to 10 GHz), but so far nothing has been detected. Kasting, the author of "How to Find a Habitable Planet," said worlds around M-class dwarf stars faced several disadvantages in the habitability department. For one thing, such planets generally end up being tidally locked to their stars — meaning that one side of the planet is always facing its parent sun while the other is always turned away.

Who is the Richest person in the world? Do you really think your government controls everything? How Rothschild became the richest family in the world? In this documentary video you will the all about Rothschild Family and his biography. The Rothschild, world kingpins, worth $500 trillion! They own Reuters, AP, and fix the price of gold... At ToBeFree, I've focused mainly on the Rockefellers, key kingpins in the US, which apparently are secretly worth more than $10 trillion. But the Rothschilds are far more wealthier, and are by many considered the greatest controlling factor worldwide — the kingpins of the world! In the late '90s, I attended an event in which Gaylon Ross was lecturing. He laid out the big picture for me that has continued to prove true. In addition to speaking about these two families, he laid out the elite's plan to create unions within the continents, and then merge all 5 continents into the one-world government which they control. Since I heard Gaylon speak and had great discussions with him after that, I've watched time and time again the globalists attempts to unite the Americas. From what I've seen, Skull and Bonesman, President Bush should be considered a traitor for how he handled just this issue alone, doing the bidding of his handlers. Here is just one tiny aspect of the Rothschild family. Under the surface, the Rothschilds long had a powerful influence in dictating American financial laws. The law records show that they were powers in the old Bank of the United States [abolished by Andrew Jackson]. Rothschild quotes: "Give me control of a nation's money and I care not who makes the laws." "I care not what puppet is placed on the throne of England to rule the Empire, ...The man that controls Britain's money supply controls the British Empire. And I control the money supply."

Under the Antarctica - Full Documentary HD The Antarctic ice sheet is one of the two polar ice caps of the Earth. It covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth. It covers an area of almost 14 million square km and contains 26.5 million cubic km of ice. That is, approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to 70 m of water in the world's oceans. In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level. The land in this area would be seabed if the ice sheet were not there. The icing of Antarctica began with ice-rafting from middle Eocene times about 45.5 million years ago and escalated inland widely during the Eocene - Oligocene extinction event about 34 million years ago. CO2 levels were then about 760 ppm and had been decreasing from earlier levels in the thousands of ppm. Carbon dioxide decrease, with a tipping point of 600 ppm, was the primary agent forcing Antarctic glaciation. The glaciation was favored by an interval when the Earth's orbit favored cool summers but Oxygen isotope ratio cycle marker changes were too large to be explained by Antarctic ice-sheet growth alone indicating an ice age of some size. The opening of the Drake Passage may have played a role as well though models of the changes suggest declining CO2 levels to have been more important. Ice enters the sheet through precipitation as snow. This snow is then compacted to form glacier ice which moves under gravity towards the coast. Most of it is carried to the coast by fast moving ice streams. The ice then passes into the ocean, often forming vast floating ice shelves. These shelves then melt or calve off to give icebergs that eventually melt. If the transfer of the ice from the land to the sea is balanced by snow falling back on the land then there will be no net contribution to global sea levels. A 2002 analysis of NASA satellite data from 1979 - 1999 showed that while overall the land ice is decreasing, areas of Antarctica where sea ice was increasing outnumbered areas of decreasing sea ice roughly 2:1. The general trend shows that a warming climate in the southern hemisphere would transport more moisture to Antarctica, causing the interior ice sheets to grow, while calving events along the coast will increase, causing these areas to shrink. A 2006 paper derived from satellite data, measures changes in the gravity of the ice mass, suggests that the total amount of ice in Antarctica has begun decreasing in the past few years. Another recent study compared the ice leaving the ice sheet, by measuring the ice velocity and thickness along the coast, to the amount of snow accumulation over the continent. This found that the East Antarctic Ice Sheet was in balance but the West Antarctic Ice Sheet was losing mass. This was largely due to acceleration of ice streams such as Pine Island Glacier. These results agree closely with the gravity changes. The estimate published in November 2012 and based on the GRACE data as well as on an improved glacial isostatic adjustment model indicates that an average yearly mass loss was 69 ± 18 Gt/y from 2002 to 2010. The West Antarctic Ice Sheet was approximately in balance while the East Antarctic Ice Sheet gained mass. The mass loss was mainly concentrated along the Amundsen Sea coast.

12,000 startups are being created everyday in China. Fifty years ago, you might have heard some parents in the U.S. try to reprimand their children by saying: “eat your food, there’s starving children in China.” But that was a long time ago. Like the asteroid that wiped out the dinosaurs millions of years ago, China’s economic growth is changing the world. An undeveloped country, suffering from famine, became an economic superpower that took over the world’s production in less than fifty years. China keeps growing faster than any other big country ever has. What mysteries lie behind its success? Three crucial factors have attributed to China’s economic miracle: a gigantic population, production efficiency and intensity and capital, in other words, its total factor productivity (TFP). Let’s dig in and examine how these three factors have taken China’s GDP to unprecedented heights. A country’s GDP per capita is that country’s GDP divided by its population. It’s an indicator for economic performance relative to size. Since China’s economic reforms in 1978, its annual GDP per capita growth rate has been steady at around 9%. That’s a remarkable performance, given that the World Banks already deems a 2% GDP per capita growth rate to be excellent. In the graph above, you can see how physical capital stock accounted for over half of China’s growth rate between 2000 and 2012. China’s TFP contributed to one third of its growth, while China’s labor force was vital during the earlier period. The mix of these three factors are what drives China’s amazing growth. Industrialization meets one billion workers China’s massive population proved to be a gift from the gods. Before China’s infamous One-Child Policy in 1979, China had an incredibly high birth rate. This eventually led to China’s working age population (15-64 years old) reaching one billion by 2014. This seemingly infinite labor force was a perfect match for industrialization. For the first stage of any pre-industrial economy, you need to focus on agriculture. This is low-skilled labor but very intensive. China properly followed the Asian Capital Development model by moving on to manufacturing. It requires more skill, but is still incredibly labor intensive. China’s massive workforce moved from the fields to the factories. Lately, China’s been stepping in its Northeast Asian rivals’ shoes - Japan and South Korea. They started transitioning into the technology and services sector. Fortunately for China, its workers’ skills, also referred to as human capital, have evolved at the same pace as its development phases. For an economy to grow, you need a big enough workforce with the necessary skills. Human capital investment skyrockets in China In the early 1990s demand for skilled employees skyrocketed as foreign investments increased. The graph below shows the rise in Chinese college admissions, particularly in urban areas.

In an interview aired by Fox on Sunday night, OJ Simpson seemed to “hypothetically” confess to the 1994 murder in Los Angeles of his ex-wife Nicole Brown and her friend Roassn Goldman. OJ and that 'weird gap' Duncan Campbell Read more In an exchange with Judith Regan, the former NFL and Hollywood star said he was at the scene of the deaths with a knife in his hand. Simpson said he had never seen so much blood in his life. He said: “It was horrible. It was absolutely horrible.” Simpson was acquitted of the murders of Brown and Goldman in 1995, after a high-profile court case. He was later convicted on civil charges. In 2008 he was sentenced to 33 years in prison over an armed robbery in Las Vegas. He was released on parole last October, having served nine years. The interview with Regan was recorded in 2006 to coincide with the release of Simpson’s book on the murders, If I Did It, which was eventually released after a number of legal delays. The interview was mothballed over public outcry and potential legal issues. More than 10 years later, Fox turned to it again thanks to renewed public interest in the Simpson case. In the interview, Simpson recounts details of the evening in question and drifts in and out of the first person. He then seems to catch himself and remembers to offer the qualifier that what he is saying is merely hypothetical. On the night in question, he said, a friend, “Charlie”, whose existence has not been substantiated, picked him up in order to go and find out what was happening at Brown’s home. When he arrived, Simpson said, he exchanged words with Goldman and Brown fell down, hurting herself. According to Simpson’s “hypothetical” recollection, Goldman then went into a “karate thing”, or stance, and Simpson replied: “You think you can kick my as*s?” Then, Simpson said, he blacked out. The next thing Simpson said he remembered was “standing there and there’s all kinds of stuff around” – meaning blood. Appearing on a Fox panel convened to discuss the interview, original prosecutor Christopher Darden said: “I think he’s confessed to murder.” Simpson also shed light on the infamous low-speed police chase that preceded his arrest. “I was being depicted as a fugitive but from the side of the roads there was more people cheering,” he said. He also made the bizarre claim that Brown and Goldman had in fact harmed him. “They killed me,” Simpson said. “Who I was was attacked and murdered during that period.” o. j. simpson

The World of PANDORA - Life After Earth http://www.advexon.com Pandora is the idyllic blue world featured in the movie Avatar. Its location is a real place: Alpha Centauri, the nearest star to our Sun and the most likely destination for our first journey beyond the solar system. Remarkably, it's anti-matter, the science fiction fuel of choice that could take us there. Normally, it's only created in powerful jets that roar out of black holes. We can now produce small quantities in Earth-bound particle colliders. Will we journey out only to plunder other worlds? Or will we come in peace? The answer may depend on how we see Earth at that time in the distant future. The year is 2154. Our planet has been ruined by environmental catastrophe. In the movie Avatar, greedy prospectors from Earth descend on the world of an innocent hunter-gatherer people called the Na'vi. Their home is a lush moon far beyond our solar system called Pandora. Could such a place exist? And could our technology... and our appetite for exploration... one day send us hurtling out to reach it? In fact, the supposed site of this fictional solar system is one of our most likely interstellar targets, until a better destination turns up. Pandora orbits a fictional gas planet called Polyphemus. Its home is a real place... Alpha Centauri... the brightest star in the southern constellation of Centaurus. At 4.37 light years away, it's part of the closest star system to our sun. Alpha Centauri is actually two stars, A and B, one slightly larger and more luminous than our own sun, the other slightly smaller. The two stars orbit one other, swinging in as close as Saturn is to our Sun... then back out to the distance of Pluto. This means that any outer planets in this system... anything beyond, say, the orbit of Mars... would likely have been pulled away by the companion and flung out into space. For this reason, Alpha Centauri was not high on planet hunters' lists... until they began studying a star 45 light years away called "Gamma Cephei." It has a small companion star that goes around it every 76 years. Now, it seems... it also has at least one planet. That world is about the size of Jupiter, and it has planet hunters excited. Perhaps two-thirds of all the stars in our galaxy are in so-called binary relationships. That means there could be many more planets in our galaxy that astronomers once assumed. At least three teams are now conducting long-term studies of Alpha Centauri... searching for slight wobbles in the light of each companion star that could indicate the presence of planets. If they find a planet that passes in front of one of the stars, astronomers will begin intensive studies to find out what it's like. One of their most promising tools will be the James Webb Space Telescope, scheduled for launch in 2014 or 2015. From a position a million miles away from Earth, it will deploy a sun shield the size of a tennis court, and a mirror over 21 feet wide. The largest space telescope ever built, it will offer an extraordinary new window into potential solar systems like Alpha Centauri. With its infrared light detectors, this telescope will be able to discern the chemical composition of a planet's atmosphere... and perhaps whether it harbors a moon like Pandora. One prominent planet hunter predicted that if a habitable world is found at Alpha Centauri, the planning for a space mission would begin immediately. Here's that star duo as seen by the Cassini spacecraft just above the rings of Saturn. To actually get to this pair of stairs, you have to travel as far as the orbit of Saturn, then go another 30,000 times further. Put another way, if the distance to Alpha Centauri is the equivalent of New York to Chicago, then Saturn would be just... one meter away. So far, the immense distances of space have not stopped us from launching missions into deep space. In 1977, the twin Voyager spacecraft were each sent on their way aboard Titan 3 Centaur rockets. After a series of gravitational assists from the giant outer planets, the spacecraft are now flying out of the solar system at about 40,000 miles per hour. They are moving so quickly that they could whip around the Earth in just 45 minutes, twice as fast as the International Space Station. Voyager I has now traveled over 110 astronomical units. That's 110 times the distance from Earth to the Sun... or about 10 billion miles. But don't hold your breath. If it was headed in the right direction, it would need another 73,000 years to travel the 273,000 astronomical units to Alpha Centauri. When it comes to space travel, we've yet to realize the dream forged by rocketeers a century ago.

Feel free to subscribe our Documentary HD Channel in HD ( http://youtu.be/cWIiTjPOcos ) A True Story About Planet Pluto http://www.advexon.com Pluto (minor-planet designation 134340 Pluto) is the largest object in the Kuiper belt, and the tenth-most-massive body observed directly orbiting the Sun. It is the second-most-massive known dwarf planet, after Eris. Like other Kuiper-belt objects, Pluto is composed primarily of rock and ice and is relatively small, approximately one-sixth the mass of the Moon and one-third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4--7.4 billion km) from the Sun. This causes Pluto to periodically come closer to the Sun than Neptune, but an orbital resonance with Neptune prevents the bodies from colliding. In 2014 it was 32.6 AU from the Sun. Discovered in 1930, Pluto was originally classified as the ninth planet from the Sun. Its status as a major planet fell into question following further study of it and the outer Solar System over the ensuing 75 years. Starting in 1977 with the discovery of the minor planet 2060 Chiron, numerous icy objects similar to Pluto with eccentric orbits were found. The most notable of these was the scattered disc object Eris, discovered in 2005, which is 27% more massive than Pluto. The understanding that Pluto is only one of several large icy bodies in the outer Solar System prompted the International Astronomical Union (IAU) to define formally in 2006 what it means to be a "planet". This definition excluded Pluto and reclassified it as a member of the new "dwarf planet" category (and specifically as a plutoid). A few astronomers hold that Pluto should have remained classified as a planet, and that other dwarf planets and even moons should be added to the roster of planets along with Pluto. Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Nix, Hydra, Kerberos, and Styx. Pluto and Charon are sometimes described as a binary system because the barycenter of their orbits does not lie within either body. The IAU has yet to formalise a definition for binary dwarf planets, and Charon is officially classified as a moon of Pluto. On July 14, 2015, the Pluto system is due to be visited by spacecraft for the first time. The New Horizons probe will perform a flyby during which it will attempt to take detailed measurements and images of the Plutoid and its moons.

Check out our new channel with 100 of HD Documentaries https://www.youtube.com/c/seosantv [Seosan TV] The characteristics of ancient Egyptian technology are indicated by a set of artifacts and customs that lasted for thousands of years. The Egyptians invented and used many simple machines, such as the ramp and the lever, to aid construction processes. They used rope trusses to stiffen the beam of ships. Egyptian paper, made from papyrus, and pottery were mass-produced and exported throughout the Mediterranean basin. The wheel, however, did not arrive until foreign influence introduced the chariot in the 16th century BC. The Egyptians also played an important role in developing Mediterranean maritime technology including ships and lighthouses. Significant advances in ancient Egypt during the dynastic period include astronomy, mathematics, and medicine. Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of farmland, which was flooded annually by the Nile river. The 3,4,5 right triangle and other rules of thumb served to represent rectilinear structures, and the post and lintel architecture of Egypt. Egypt also was a center of alchemy research for much of the western world. The Nile valley has been the site of one of the most influential civilizations in the world with its architectural monuments, which include the pyramids of Giza and the Great Sphinx—among the largest and most famous buildings in the world. Giza Plateau, Cairo. Khafre's pyramid in the background The most famous pyramids are the Egyptian pyramids—huge structures built of brick or stone, some of which are among the largest constructions by humans. Pyramids functioned as tombs for pharaohs. In Ancient Egypt, a pyramid was referred to as mer, literally "place of ascendance." The Great Pyramid of Giza is the largest in Egypt and one of the largest in the world. The base is over 13 acres (53,000 m2) in area. It is one of the Seven Wonders of the World, and the only one of the seven to survive into modern times. The Ancient Egyptians capped the peaks of their pyramids with gold and covered their faces with polished white limestone, although many of the stones used for the finishing purpose have fallen or been removed for use on other structures over the millennia. The Red Pyramid of Egypt (c.26th century BC), named for the light crimson hue of its exposed granite surfaces, is the third largest of Egyptian pyramids. Menkaure's Pyramid, likely dating to the same era, was constructed of limestone and granite blocks. The Great Pyramid of Giza (c. 2580 BC) contains a huge granite sarcophagus fashioned of "Red Aswan Granite." The mostly ruined Black Pyramid dating from the reign of Amenemhat III once had a polished granite pyramidion or capstone, now on display in the main hall of the Egyptian Museum in Cairo (see Dahshur). Other uses in Ancient Egypt, include columns, door lintels, sills, jambs, and wall and floor veneer. The ancient Egyptians had some of the first monumental stone buildings (such as in Sakkara). How the Egyptians worked the solid granite is still a matter of debate. Archaeologist Patrick Hunt has postulated that the Egyptians used emery shown to have higher hardness on the Mohs scale. Regarding construction, of the various methods possibly used by builders, the lever moved and uplifted obelisks weighing more than 100 tons.

10 Tips To Feel More Energetic (Part 1) How To Feel More Energetic - Top 10 Tips Part 2 is available here: https://youtu.be/gDO2jGSNmA8 Do you struggle to get out of bed, feel constantly drained and rely on pick-me-ups such as protein bars, coffee and sugary treats to get you through the day? If so, you’re far from alone. Here are the Top 10 Tips To Feel More Energetic throughout the day. 1. Rule Out Existing Health Problems Fatigue is a common symptom of many illnesses, including diabetes, heart disease, and thyroid disease. If you are constantly tired, the first step is to talk to your doctor to rule out any possible existing health problems which could be causing it. Many medications can also contribute to fatigue. These include blood pressure medicines, antihistamines, diuretics, and other drugs. If you begin to experience fatigue after starting a new medication, tell your doctor so you can find something more suitable to you. 2. Key Nutrients We all have increasingly busy lives, so it’s essential to provide the body with enough vitamins and key nutrients to get through the day. Iron - Many people have low enough iron levels to be anaemic but a blood test will pick up any iron problems you may have. Regardless of your iron levels, it’s a good idea to include plenty of iron-rich foods in your diet such as dried fruit and dark green vegetables like Spinach. B-vitamins - B vitamins are particularly vital as they’re required by the body to convert the food you eat into energy. They are most commonly found in grains such as brown rice, barley and oats, as well as lean proteins such as oily fish and turkey. Protein - Avoiding protein will leave you exhausted, as it’s a vital energy giver. Protein provides slow burning energy, so it’s great for fighting fatigue for the whole day. Good protein sources are meat, fish, cheese, tofu, beans, lentils, yogurt, nuts and seeds. 3. Physical Activity It might be the last thing you feel like, but avoiding exercise because you’re tired actually makes you feel worse. Exercise has consistently been linked to improved vigour and overall quality of life. This is because regular exercise makes your heart and lungs work more efficiently, delivering oxygen and vital nutrients around the body. That’s the equivalent of improving the fuel efficiency of a car. It gives you more energy for any kind of activity. 4. Yoga & Meditation Although almost any exercise is good, yoga and other meditative exercises may be especially effective for boosting energy. After just six weeks of once-a-week yoga classes, volunteers in a British study reported improvements in clear-mindedness, energy, and confidence. It’s never too late to try, either. Many elderly people who struggle with chronic fatigue turn to these gentle and light exercises and stretching routines. Use this, combined with controlled abdominal breathing and you will feel more alert than ever once your body adjusts. 5. Drink Plenty Of Water Dehydration zaps energy and impairs physical performance. It has also been shown to decrease alertness and concentration. The easiest way to tell if you’re drinking enough water or not is to check the colour of your urine. Urine should be pale yellow or straw coloured when you are hydrated enough. If it’s darker than that, you need to drink more water. Losing as little as 2% of your body’s normal water content can take its toll on your energy levels, so make sure you’re constantly sipping on a cup of water. If you find water too boring by itself, add mint, basil, lemon or cucumber to liven up the flavor. https://www.facebook.com/toptruths/ https://www.toptruths.com https://www.advexon.tv LIKE / SHARE / SUBSCRIBE Playlists: TOP Educational: http://bit.ly/TTEducational TOP 10: http://bit.ly/TOPTruthsTop10 TOP Cotroversial: http://bit.ly/TOPTruthsControversial TOP Science & Tech: http://bit.ly/TOPTruthsScTech Powered by Advexon: http://advexon.tv/ #Toptruths #top10 #top100 #trending #trends #worldsbest #coolstuff #didyouknow #toptruth #truth #top2016 #amazing #awesome #cool #sexy #interesting #facts #exposed #advexon #google #facebook #youtube #inspirational #motivational

Most Mysterious Archaeological Discoveries Ever Made https://www.facebook.com/toptruths/ Digging up items from the past always remind us how creative the minds of our ancestors were. Such discoveries are also a great chance to see the remains of items which are centuries old. Here are the Most Mysterious Archaeological Discoveries Ever Made. 9 Voynich Manuscript The Voynich Manuscript is an illustrated codex hand-written in an unknown writing system. The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438), and it may have been composed in Northern Italy during the Italian Renaissance. Some of the pages are missing, with around 240 remaining. 8 The Mount Owen Claw Nearly three decades ago, a team of archaeologists were carrying out an expedition inside a large cave system on Mount Owen in New Zealand when they stumbled across a frightening and unusual object — an enormous, dinosaur-like claw still intact with flesh and scaly skin. The claw was so well-preserved that it appeared to have come from something that had only died very recently. 7 Sacsayhuaman Sacsayhuaman is one of the most stunning Inca ruins, located on the northern outskirts of the old city of Cusco, Peru, the former capital of the Inca Empire. Built like a fortress, the complex covers a huge area, but they constitute perhaps only a quarter of the original complex, which, at the time, could have easily housed more than 10,000 people. 6 Nazca Lines The Nazca Lines are a series of large ancient geoglyphs in the Nazca Desert, in southern Peru. They are so large; they can only be seen when flying over the Peruvian desert. The largest figures are up to 370 meters long and they were designated as a UNESCO World Heritage Site in 1994. Scholars believe the Nazca Lines were created by the Nazca culture between 500BCE and 500CE. The figures vary in complexity. Hundreds are simple lines and geometric shapes; more than 70 are zoomorphic designs of animals, such as birds, fish, llamas, jaguars, monkeys, or human figures. 5 Gobekli Tepe Six miles from Urfa, an ancient city in south-eastern Turkey, Klaus Schmidt made one of the most startling archaeological discoveries of our time: massive carved stones about 11,000 years old, crafted and arranged by prehistoric people who had not yet developed metal tools or even pottery. These megaliths predate Stonehenge by around 6,000 years. 4 Terracotta Army In 1974, a group of archaeologists in Xian, China made an excavation which became the discovery of the greatest funeral art ever, the Terracotta army. They found thousands of clay soldiers buried near the tomb of emperor Qin Shi Huang. He was the first emperor of China. The clay soldiers were buried with him for protection from different forces after death. This ancient complex is around 2,200 years old. The archaeologists also found different weapons along with the sculptures. They were perfectly arranged within different clay corridors. 3 Moai Statues (Easter Island Heads) The Moai statues of Easter Island, also known as the Easter Island Heads, are one of most mysterious and iconic archaeological discoveries ever made. These statues are the main tourist attractions of Easter Island. The Moai statues were carved by ancient people of Rapa Nui between 1300 to 1500CE. There are 288 Maoi statues in total, situated on various massive stone platforms on the Island. 2 Stonehenge Stonehenge, one of the most famous landmarks in the UK, is regarded as a British cultural icon. It is a prehistoric monument made up of a ring many large free-standing stones. Each stone is around 13ft high, 7ft wide and weighs around 25 tonnes. The actual purpose of Stonehenge is still unknown, although there are several hundred burial mounds nearby. Archaeologists have dated the human remains to be around 4,500 years old, buried at some point between 3000BCE and 2000BCE. 1 Great Pyramids It’s argued that the Egyptian Pyramids are the greatest ancient structures ever to be created. Even though many civilizations built pyramids, the Egyptian pyramids are a cut above the rest. The Great Pyramid of Giza always makes it on lists of the greatest wonders of the world, and for good reason.

Alien Worlds Beyond Our Solar System - Full Documentary HD Alien Earth | Life Beyond Earth One of eight new planets spied in distant solar systems has usurped the title of "most Earth-like alien world", astronomers have said. All eight were picked out by Nasa's Kepler space telescope, taking its tally of such "exoplanets" past 1,000. But only three sit safely within the "habitable zone" of their host star - and one in particular is rocky, like Earth, as well as only slightly warmer. The find was revealed at a meeting of the American Astronomical Society. Red sky The three potentially habitable planets join Kepler's "hall of fame", which now boasts eight fascinating planetary prospects. And researchers say the most Earth-like of the new arrivals, known as Kepler 438b, is probably even more similar to our home than Kepler 186f - which previously looked to be our most likely twin. At 12% larger than Earth, the new claimant is bigger than 186f but it is closer to our temperature, probably receiving just 40% more heat from its sun than we do from ours. So if we could stand on the surface of 438b it may well be warmer than here, according to Dr Doug Caldwell from the Seti (Search for Extra-Terrestrial Intelligence) Institute in California. "And it's around a cooler [red dwarf] star... so your sky would look redder than ours does to us," Dr Caldwell said. That first-person encounter, however, is unlikely - both because the planet is 475 light-years away and because we still have essentially no idea what it's made of. Images from the Kepler telescope, which trails behind the Earth and peers far into the distance as we orbit our own sun, are used to identify far-off planets by observing "transits". This refers to the dimming of a star's light when a planet passes in front of it. A large team of researchers then uses additional data from Earth-bound telescopes to further explore these unfamiliar solar systems. They try to calculate how big the planets are, and how closely they orbit their host stars. Not everything that causes such a dimming eventually turns out to be a planet, however. At the same time as the eight confirmed new exoplanets were announced by a 26-strong team spanning Nasa and multiple US institutions, the Kepler mission's own scientists released another tranche of more than 500 "candidate" planets. "With further observation, some of these candidates may turn out not to be planets," said Kepler science officer, Fergal Mullally. "Or as we understand their properties better, they may move around in, or even outside, the habitable zone." 'Star Trek' scenario Even once scientists have anointed a candidate as a confirmed exoplanet, the question of whether or not it is "Earth-like" is a fraught one, with fuzzy boundaries. The size of the habitable, or "Goldilocks" zone, where a planet is far enough from its sun to hold water but not so distant that it freezes, depends on how confident scientists want to be with their guess-work. According to Dr Cardwell, just three of the eight new exoplanets can be confidently placed in that zone - and only two of those are probably rocky like the Earth. More detailed description is very difficult. "From the Kepler measurements and the other measurements we made, we don't know if these planets have oceans with fish and continents with trees," Dr Caldwell told BBC News. "All we know is their size and the energy they're receiving from their star. "So we can say: Well, they're of a size that they're likely to be rocky, and the energy they're getting is comparable to what the Earth is getting. "As we fill in these gaps in our solar system that we don't have, we learn more about what it means to be Earth-like, in some sense." Speaking at a related event at the conference, Prof Debra Fischer from Yale University said she remembered a time before the first exoplanet was discovered, more than two decades ago. "I remember astronomers before that point being very worried," she said. "We really had to step back and say: Maybe the Star Trek picture is wrong. That filled me with despair." Prof Fischer said that sensitive telescopes like Kepler had ushered in an era of "amazing and impressive work". "We're talking about a planet - and we can only see its star with a powerful telescope. "And we can draw graphs and sketch its composition and have serious scientific discussions. This is incredible." Subscribe us Thanks for watching *Subscribe for more HD Documentaries

Predicting the future is a handy skill to have when it comes to enrolling in college, starting a fresh career, or investing in new skills. Here are, according to U.S. News, the Top 10 Fields To Invest Your Future In. 1. Data Crunching The era of big data is just getting started, with many firms eager to tap vast new databases to gather more info on their customers, their competitors, and even themselves. The challenge isn't just crunching numbers; it's making sense of them, and gaining useful insights that can be translated into a business edge. Marketing and market research are two growing fields where the use of data is exploding. 2. Counselling & Therapy There's now widespread recognition that mental health is as important as physical health, which is likely to increase demand for professionals in this field. The US Bureau of Labour Statistics (or the BLS) expects the need for marriage and family therapists, as one example, to grow 41 percent by 2020. 3. Scientific Research New technology will continue to generate breakthroughs in medicine, manufacturing, transportation, and many other fields, which means there will be strong demand for workers schooled in biology, chemistry, maths, and engineering. Some areas that show particular promise: biotechnology and biomedicine, nanotechnology, robotics, and 3D printing, which allows the manufacture of physical products from a digital data file. 4. Computer Engineering A lot of software development is done overseas these days, but the need for high-level computer experts able to tie systems together is still strong. In finance and investing, for instance, high-speed computing is increasingly a prime competitive advantage. And most big companies will need networks that are faster, more seamless, and more secure. 5. Veterinarians Pets are more popular than ever, and some of them get medical care that's practically fit for a human. The BLS expects the need for vets to rise 36 percent by 2020. 6. Environmental & Conservation Science Making better use of the planet's resources will be essential as population growth strains existing infrastructure. Green energy, despite some political controversy, still seems likely to boom. Developers need more efficient ways to heat and cool buildings. And dealing with global warming may require new technology not even on the drawing board yet. 7. Healthcare It's well-known that the aging of the baby boomers will require more caregivers in many specialties. Some healthcare jobs tend to be low-paying, with a lot of workers flocking to what are supposed to be "recession-proof" fields. And the need to lower overall healthcare costs could pinch some doctors, hospital workers, and diagnosticians. But demand should be strong for nurses, optometrists, audiologists, dentists, physical therapists, and some doctor specialists. 8. Management The boss earns a lot for good reason: His job isn't as easy as it might seem. Effective management in the future will require basic business knowledge plus the ability to oversee operations in many locations and countries, and some technical know-how. Anybody who can improve a unit's performance while lowering costs should rise quickly. The BLS and IBISWorld also expect growing demand for some support fields such as human relations, benefits administration, and event planning. 9. Finance The movement and management of money is technically complex, and integral to most companies. Plus, non-traditional investing firms such as hedge funds and private-equity firms are likely to grow as the traditional banking sector complies with new regulations and reins in risk-taking. That means there will be more need for finance experts. There may even be a shortage as students once interested in finance veer into other fields, turned off by the 2008 financial crisis and the vilification of banks. 10. Entrepreneurship It's often overlooked, but the need for innovators running their own businesses could be more important than ever in 2020. Forecasters expect strong growth in traditional businesses such as used-car dealers, hair and nail salons, pet grooming, and office services, which means anybody able to come up with better, cheaper ways to serve customers will reap a windfall. Technology start-ups will no doubt keep changing the way consumers work and live. And nobody really knows what the next iPad, Twitter, or Pinterest will be—except, perhaps, some entrepreneur who's dreaming about it right now. He or she may have a bigger impact on life in 2020 than anything the forecasters see coming.

Why do we create a Humanoid Robot? http://www.advexon.com http://asimo.honda.com/ The dream sounds simple. Design a robot that can duplicate the complexities of human motion and genuinely help people. An easy task? Not at all. ASIMO took more than two decades of persistent study, research, and trial and error before Honda engineers achieved their dream of creating an advanced humanoid robot. The Past: In 1986, Honda engineers set out to create a walking robot. Early models (E1, E2, E3) focused on developing legs that could simulate the walk of a human. The next series of models (E4, E5, E6) were focused on walk stabilization and stair climbing. Next, a head, body and arms were added to the robot to improve balance and add functionality. Honda's first humanoid robot, P1 was rather rugged at 6' 2" tall, and 386 lbs. P2 improved with a more friendly design, improved walking, stair climbing/descending, and wireless automatic movements. The P3 model was even more compact, standing 5' 2" tall and weighing 287 lbs. The Present: ASIMO is the culmination of two decades of humanoid robotics research by Honda engineers. ASIMO can run, walk on uneven slopes and surfaces, turn smoothly, climb stairs, and reach for and grasp objects. ASIMO can also comprehend and respond to simple voice commands. ASIMO has the ability to recognize the face of a select group of individuals. Using its camera eyes, ASIMO can map its environment and register stationary objects. ASIMO can also avoid moving obstacles as it moves through its environment. The Future: As development continues on ASIMO, today Honda demonstrates ASIMO around the world to encourage and inspire young students to study the sciences. And in the future, ASIMO may serve as another set of eyes, ears, hands and legs for all kinds of people in need. Someday ASIMO might help with important tasks like assisting the elderly or a person confined to a bed or a wheelchair. ASIMO might also perform certain tasks that are dangerous to humans, such as fighting fires or cleaning up toxic spills.

What If other planets replaced the moon http://www.advexon.com Please watch full screen in HD if possible. So the basic idea is, each planet you see is the size it would appear in the sky if it shared an orbit with the moon, 380,000 kms from earth. I created this video in After Effects, and because of certain technical considerations had to keep the field of view at 62 degrees. That means the foreground element is not precisely to scale. I realized this after the fact and may update the video at some point in the future. All planets are to correct scale with one another in any case.

http://www.advexon.com Please Subscribe us :) To be spacefaring is to be capable of and active in the art of space travel or space transport, the operation of spacecraft or spaceplanes. It involves a knowledge of a variety of topics and development of specialised skills including (but not limited to): aeronautics; astronautics; programs to train astronauts; space weather and forecasting; ship-handling and small craft handling; operation of various equipment; spacecraft design and construction; atmospheric takeoff and reentry; orbital mechanics (aka astrodynamics); communications; engines and rockets; execution of evolutions such as towing, micro-gravity construction, and space docking; cargo handling equipment, dangerous cargoes and cargo storage; spacewalking; dealing with emergencies; survival at space and first aid; fire fighting; life support. The degree of knowledge needed within these areas is dependent upon the nature of the work and the type of vessel employed. "Spacefaring" is analogous to seafaring. Presently there has never been a crewed mission outside the Earth-Moon system (so far as the human inhabitants of planet earth are concerned). However, the United States, Russia, China, and European Space Agency countries have plans in various stages to travel to Mars. (See Manned mission to Mars.) Spacefaring entities are commonly nations. Spacefaring nations are those capable of independently building and launching craft into space. Although, a growing number of private entities are achieving space travel, largely suborbital

Transhumanism http://www.advexon.com/ (abbreviated as H+ or h+) is an international cultural and intellectual movement with an eventual goal of fundamentally transforming the human condition by developing and making widely available technologies to greatly enhance human intellectual, physical, and psychological capacities. Transhumanist thinkers study the potential benefits and dangers of emerging technologies that could overcome fundamental human limitations, as well as the ethics of developing and using such technologies. They speculate that human beings may eventually be able to transform themselves into beings with such greatly expanded abilities as to merit the label "posthuman". The contemporary meaning of the term transhumanism was foreshadowed by one of the first professors of futurology, FM-2030, who taught "new concepts of the Human" at The New School in the 1960s, when he began to identify people who adopt technologies, lifestyles and worldviews transitional to "posthumanity" as "transhuman". This hypothesis would lay the intellectual groundwork for the British philosopher Max More to begin articulating the principles of transhumanism as a futurist philosophy in 1990, and organizing in California an intelligentsia that has since grown into the worldwide transhumanist movement. Influenced by seminal works of science fiction, the transhumanist vision of a transformed future humanity has attracted many supporters and detractors from a wide range of perspectives. Transhumanism has been characterized by one critic, Francis Fukuyama, as among the world's most dangerous ideas, to which Ronald Bailey countered that it is rather the "movement that epitomizes the most daring, courageous, imaginative, and idealistic aspirations of humanity".

Even after dozens of spacecraft have been sent to Mars, much remains unknown about that world. Here are some of the biggest unsolved mysteries we have about Mars. Why does Mars have two faces? Scientists have been puzzling over the differences between the two sides of Mars for decades. The northern hemisphere of the planet is smooth and low — it is among the flattest, smoothest places in the solar system, potentially created by water that once flowed across the Martian surface. Meanwhile, the southern half of the Martian surface is rough and heavily cratered, and about 2.5 miles to 5 miles (4 km to 8 km) higher in elevation than the northern basin. Recent evidence suggests the vast disparity seen between the northern and southern halves of the planet was caused by a giant space rock smacking into Mars long ago. Still, there are ways to produce methane without life, such as volcanic activity. ESA's ExoMars spacecraft planned for launch in 2016 will study the chemical composition of Mars' atmosphere to learn more about this methane. Does liquid water run on the surface of Mars now? Although large amounts of evidence suggest that liquid water once ran on the surface of Mars, it remains an open question as to whether or not it occasionally flows on the face of the Red Planet now. The planet's atmospheric pressure is too low, at about 1/100th of Earth's, for liquid water to last on the surface. However, dark, narrow lines seen on Martian slopes hint that saltwater could be running down them every spring. Were there oceans on Mars? Numerous missions to Mars have revealed a host of features on the Red Planet that suggest it was once warm enough for liquid water to run across its surface. These features include what appear to be vast oceans, valley networks, river deltas and minerals that required water to form. Nevertheless, astronauts seem eager to find out. For example, this year six volunteers lived in a pretend spacecraft for nearly a year and a half in the so-called Mars500 project, the longest spaceflight simulation ever conducted, aimed at replicating a manned mission to Mars from beginning to end. There are even numerous volunteers for a one-way trip to the Red Planet. Tiny rock-eating microbes could mine precious extraterrestrial resources from Mars and pave the way for the first human colonists, and farmers could grow crops on its surface. The mystery as to whether or not humans will ever go to Mars may rest largely on whether or not the powers-that-be can be convinced to go there.

http://www.advexon.com/ Technology (from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a pre-existing solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, including machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology. The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of Earth's environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.

What is Democracy and from where did it come? 360p Definition of democracy 1a: government by the people especially: rule of the majority b: a government in which the supreme power is vested in the people and exercised by them directly or indirectly through a system of representation usually involving periodically held free elections... One of the most commonly encountered questions about the word democracy has nothing to do with its spelling or pronunciation, and isn’t even directly related to the meaning of the word itself. That question is “is the United States a democracy or a republic?” The answer to this, as with so many other questions about meaning, may be phrased as some form of “it depends.” Some people believe that a country calling itself a democracy must be engaged in direct (or pure) democracy, in which the people of a state or region vote directly for policies, rather than elect representatives who make choices on their behalf. People who follow this line of reasoning hold that the United States is more properly described as a republic, using the following definition of that word: ”a government in which supreme power resides in a body of citizens entitled to vote and is exercised by elected officers and representatives responsible to them and governing according to law.” However, both democracy and republic have more than a single meaning, and one of the definitions we provide for democracy closely resembles the definition of republic given above: “a government in which the supreme power is vested in the people and exercised by them directly or indirectly through a system of representation usually involving periodically held free elections.” So if someone asks you if the United States is a democracy or a republic, you may safely answer the question with either “both” or “it depends.”

http://www.advexon.com/ The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisis is being caused by technology and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes. Over time intervals of hundreds of millions of years, random celestial events pose a global risk to the biosphere, which can result in mass extinctions. These include impacts by comets or asteroids with diameters of 5--10 km (3.1--6.2 mi) or more, and the possibility of a massive stellar explosion, called a supernova, within a 100-light-year radius from the Sun, called a Near-Earth supernova. Other large-scale geological events are more predictable. If the long-term effects of global warming are disregarded, Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the quaternary glaciation comes to an end. These periods are caused by eccentricity, axial tilt, and precession of the Earth's orbit. As part of the ongoing supercontinent cycle, plate tectonics will probably result in a supercontinent in 250--350 million years. Some time in the next 1.5--4.5 billion years, the axial tilt of the Earth may begin to undergo chaotic variations, with changes in the axial tilt of up to 90°. During the next four billion years, the luminosity of the Sun will steadily increase, resulting in a rise in the solar radiation reaching the Earth. This will cause a higher rate of weathering of silicate minerals, which will cause a decrease in the level of carbon dioxide in the atmosphere. In about 600 million years, the level of CO 2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees. Some plants use the C4 carbon fixation method, allowing them to persist at CO 2 concentrations as low as 10 parts per million. However, the long-term trend is for plant life to die off altogether. The extinction of plants will be the demise of almost all animal life, since plants are the base of the food chain on Earth. In about 1.1 billion years, the solar luminosity will be 10% higher than at present. This will cause the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end. Following this event, the planet's magnetic dynamo may come to an end, causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere. Four billion years from now, the increase in the Earth's surface temperature will cause a runaway greenhouse effect. By that point, most if not all the life on the surface will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded to cross the planet's current orbit.

America's Broken Education System - Full Documentary Broken Education System of America Everything in American education is broken. Or so say the policy elites, from the online learning pioneer Sal Khan to the journalist-turned-reformer Campbell Brown. As leaders of the XQ project succinctly put it, we need to “scrap the blueprint and revolutionize this dangerously broken system.” This, they explain, is the sad truth. The educational system simply stopped working. It aged, declined, and broke. And now the nation has a mess on its hands. But there’s good news, too. As Michelle Rhee’s group, StudentsFirst, declares: Americans can “work together to fix this broken system.” All it takes is the courage to rip it apart. This is how the argument goes, again and again. The system used to work, but now it doesn’t. And though nobody inside schools seems to care, innovators outside the establishment have developed some simple solutions. The system can be rebuilt, reformers argue. But first, it must be torn down.

Stephen Hawking As PDF Stephen William Hawking was an English theoretical physicist, cosmologist, author, and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His key exploration was in the areas of theoretical cosmology, focusing on the evolution of the universe as governed by the laws of general relativity. He is known for his work related to the study of black holes. With the theoretical prediction that black holes emit radiation, a theory called ‘Hawking radiation,' he became the first to set forth a cosmology explained by a union of the general theory of relativity and quantum mechanics. Hawking suffered from a rare and life-threatening condition of Amyotrophic Lateral Sclerosis, a condition he suffered all of his adult life. The illness started when he was 21 and pursuing his PhD from Cambridge University. For a major part of his later life, he was almost completely paralyzed and communicated through a speech generating device. Not succumbing to the despair of the disease, Hawking devoted all his life to his work and research. He was the Lucasian Professor of Mathematics at the University of Cambridge for around three decades and an Honorary Fellow of the Royal Society of Arts. For his contribution to the study of universe and his pioneering work in cosmology, he was made a Commander of the Order of the British Empire.

It is Tiny. but *very* close Dione would be on a collision course, it's orbital distance from Saturn is Nearly identical to our Moon's orbit around Earth Titan, which is Larger than our Moon, is outside the orbit of Dione **************** on Jupiter, you might be able to make out the 4 big moons, They all have orbits larger than our moons orbit. but I stuck them on the far side of jupiter so that they could be seen so it looks as if they are closer (to Jupiter) than they really are. *************** Video creation method I created an Earth Moon system in 3dsmax, with accurate sizes and accurate orbital distances.. I than matched video of the real Moon with my video camera, against my model. I also researched the correct FOV of my video camera. I used both methods to verify my Virtual camera's FOV (around 47 degrees).

Saturn + RINGS is larger than Jupiter 3, We would suffer from really really horrible tides, and Volcanoes And some pretty bad Radiation from Jupiter. It *could* strip away our atmosphere, but haven't done the math. Eventually our planet would become tidally locked (that is the same side of Earth would always face Jupiter. we would Still have some bad tides and volcanoes from being in a slightly ellipitical orbit, and from the other moons of Jupiter, and the Sun having tidal influence. I have not calculated how bad the Tides would be. A Simple guess would be at Least 300 times more exaggerated than they are now, This figure could be way off, it's simply an educated guess. 4, We would not be in the rings of Saturn. Or to rephrase that, we would not be in any of the Visable rings of Saturn, There are some very very faint rings that strech out far that we would be in, but i did not model them. 5, We would not be crushed by the Gravity of Jupiter, This is not how orbiting works!. However, at the Roche limit, we WOULD become a new ring system, The Roche limit is *about* 36,000km above the "surface" of Jupiter or 106,000km from the center of Jupiter. So, to reiterate if the center of Jupiter was 106,000km away from the center of the earth, Our planet would become a new Ring system of Jupiter. 6, I did not model the Ring of debris around Uranus (this faq will be deleted in a few days) 7, This is not an ad for any beer company, no one has endorsed me, or this animation, It's just the traffic that drove by. 8, There is Ring Shine on Saturn, but it is very faint, the Rings are reflecting light onto Saturn in the animation. The moon that flies by is Tethys 9, I love Pluto, and Mercury. They are left off because they are too small. Pluto is smaller than our Moon, and Mercury is not significantly larger than our Moon. 10, The "Sun" i used for lighting the planets is slightly off from reality, this was done so that they weren't totally dark and boring 11 FOV is about 47 degrees 12 Orbiting! Yes! we would be a moon of Saturn, Jupiter, Uranus, and Neptune. They are much more massive than the Earth. Venus is about the same size of the Earth and we would orbit around a center point between us 13 Rotation rates and axial tilts are not accurate to anything 14 Radius of the Sun is 695,500 km, and hence if it were where our Moon is, we would be engulfed by it

The Lost City of Atlantis - HD Documentary 2015 Atlantis is a legendary "lost" island subcontinent often idealized as an advanced, utopian society holding wisdom that could bring world peace. The idea of Atlantis has captivated dreamers, occultists and New Agers for generations. Unlike many legends whose origins have been lost in the mists of time, we know exactly when and where the story of Atlantis first appeared. The story was first told in two of Plato's dialogues, the "Timaeus" and the "Critias," written about 330 B.C. Though today Atlantis is often thought of as a peaceful utopia, the Atlantis that Plato described in his fable was very different. In his book "Frauds, Myths and Mysteries: Science and Pseudoscience in Archaeology" (McGraw-Hill, 2013) professor of archaeology Ken Feder summarizes the story: "A technologically sophisticated but morally bankrupt evil empire — Atlantis — attempts world domination by force. The only thing standing in its way is a relatively small group of spiritually pure, morally principled and incorruptible people — the ancient Athenians. Overcoming overwhelming odds ... the Athenians are able to defeat their far more powerful adversary simply through the force of their spirit. Sound familiar? Plato's Atlantean dialogues are essentially an ancient Greek version of 'Star Wars.'" As propaganda, the Atlantis legend is more about the heroic Athens than a sunken civilization; if Atlantis really existed today and was found, its residents would probably try to kill and enslave us all. It's clear that Plato made up Atlantis as a plot device for his stories because there are no other records of it anywhere else in the world. There are many extant Greek texts; surely someone else would have also mentioned, at least in passing, such a remarkable place. There is simply no evidence from any source that the legends about Atlantis existed before Plato wrote about it. Atlantis resurfaces For most of the past two millennia, no one thought much about Atlantis; it was just what it appeared to be: a fictional place mentioned in a fable by the ancient Greek philosopher. The idea that Atlantis was an actual lost historical location is a very recent idea, first proposed by a writer named Ignatius Donnelly in 1881. He believed that most of the important accomplishments of the ancient world — such as metallurgy, agriculture, religion and language — must have come from Atlantis. In essence, he argued that ancient cultures weren't sophisticated enough to develop these things on their own, so they must have spread from some unknown advanced civilization. (It is similar to the widely discredited "ancient astronauts" idea, that Egyptians were not smart enough to build pyramids, and thus extraterrestrials must have helped them.) Later writers elaborated on Donnelly's theories, adding their own opinions and speculations. These included mystic Madame Blavatsky (in her 1888 book, "The Secret Doctrine") and famous psychic Edgar Cayce in the 1920s and 1930s. Cayce, who put a fundamentalist Christian spin on the Atlantis story, gave psychic readings for thousands of people — many of whom, he claimed, had past lives in Atlantis. Unfortunately, none of the information was verifiable, and Cayce wrongly predicted that the continent would be discovered in 1969. Charles Berlitz, author of many popular books on the paranormal and unexplained phenomena, researched Atlantis and wrote a 1969 book titled "The Mystery of Atlantis." Berlitz, whose family created the famous language-learning courses, not only became convinced that Atlantis was real but also that it was the source of the Bermuda Triangle mystery, a subject he explored in his 1974 best-seller "The Bermuda Triangle." Berlitz's wild ideas about the Bermuda Triangle — and, by extension, Atlantis — were definitively debunked the following year by researcher Larry Kusche, author of "The Bermuda Triangle Mystery — Solved." Thousands of books, magazines and websites are devoted to Atlantis, and it remains a popular topic in New Age circles.

Comet Crashing Into Earth - Full Documentary HD With the Delta Aquarid meteor shower going on right now, and the crowd-favorite Perseid meteor shower hot on its heels, the next few weeks are going to be the prime-time to watch some shooting stars light up the night sky. But while dust-size bits of comets sizzling through our atmosphere put on a pretty awesome show, the consequences of Earth confronting one of these comets head-on could actually be pretty disastrous. It's not something that you should be worried about, of course. NASA is on the lookout for any cosmic objects on a crash course with our planet, and it's found that the chances of us colliding with a comet or asteroid anytime soon are pretty low. It's still interesting to think about, though. What would happen if one of these ancient, celestial chunks of ice, dust, and rock smacked into our planet? The 16-mile-wide Swift-Tuttle comet — the progenitor of the Perseid meteor shower —hurtles through space at about 36 miles per second, more than 150 times the speed of sound. If a comet of this size struck Earth, then the energy of the impact would be about as much as 300 times that of the asteroid that scientists believed wiped out the dinosaurs, Donald Yeomans, a senior research scientist at NASA's Jet Propulsion Laboratory, told LiveScience. And the size of a comet or asteroid isn't the only thing to consider with cosmic collisions. While the impact of the comet would be pretty destructive, the brunt of the damage would come from the gases it released in Earth's atmosphere. "Sulfur dioxide would initially cause cooling, and then carbon dioxide would lead to long-term warming," LiveScience writes. "An event like this would likely cause the planet's climate to change drastically, leading to mass extinctions around the globe." A comet colliding with Earth wouldn’t necessarily signal mass extinctions and the end of human civilization, though. While a comet landing smack dab in the ocean could trigger earthquakes and tsunamis, its atmospheric effects would actually be eased by the ocean. Considering that 70% of Earth is covered in ocean, our odds aren't terrible. But let's hope that we don't have to roll the dice anytime soon.

Exploring The Southern Stars - Full Documentary "Billions and billions" of stars in a galaxy (after a quote often mistakenly attributed to Carl Sagan) is how many people imagine the number of stars you would find in one. Is there any way to know the answer for sure? "It's a surprisingly difficult question to answer. You can't just sit around and count stars, generally, in a galaxy," said David Kornreich, an assistant professor at Ithaca College in New York State. He was the founder of the "Ask An Astronomer" service at Cornell University. Even in the Andromeda Galaxy — which is bright, large and relatively close by Earth, at 2.3 million light-years away — only the largest stars and a few variable stars (notably Cepheid variables) are bright enough to shine in telescopes from that distance. A sun-size star would be too difficult for us to see. So astronomers estimate, using some of the techniques below. Advertisement Massive investigation The primary way astronomers estimate stars in a galaxy is by determining the galaxy's mass. The mass is estimated by looking at how the galaxy rotates, as well as its spectrum using spectroscopy. All galaxies are moving away from each other, and their light is shifted to the red end of the spectrum because this stretches out the light's wavelengths. This is called "redshift." In a rotating galaxy, however, there will be a portion that is more "blueshifted" because that portion is slightly moving toward Earth. Astronomers must also know what the inclination or orientation of the galaxy is before making an estimate, which is sometimes simply an "educated guess," Kornreich said. A technique called "long-slit spectroscopy" is best for performing this type of work. Here, an elongated object such as a galaxy is viewed through an elongated slit, and the light is refracted using a device such as a prism. This breaks out the colors of the stars into the colors of the rainbow. Some of those colors will be missing, displaying the same "patterns" of missing portions as certain elements of the periodic table. This lets astronomers figure out what elements are in the stars. Each type of star has a unique chemical fingerprint that would show up in telescopes. (This is the basis of the OBAFGKM sequence astronomers use to distinguish between types of stars.) Any kind of telescope can do this sort of spectroscopy work. Kornreich often uses the 200-inch telescope at the Palomar Observatory at the California Institute of Technology, but he added that almost any telescope of sufficient size would be adequate. The ideal would be using a telescope in orbit because scattering occurs in Earth's atmosphere from light pollution and also from natural events — even something as simple as a sunset. The Hubble Space Telescope is one observatory known for this sort of work, Kornreich added. The number of stars is approximately … So is there any way to figure out how many stars are for sure? In the end, it comes down to an estimate. In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out. Other mass estimates bring the number up to 400 billion. The caveat, Kornreich said, is that these numbers are approximations. More advanced models can make the approximation more accurate, but it would be very difficult to count the stars one by one and tell you for sure how many are in the galaxy.

In the 400 years since Galileo Galilei first held a telescope to the heavens, astronomers have laid bare some of the deepest mysteries of the cosmos. They have seen comets crash into planets, found oceans inside moons, and witnessed the shudder of spacetime as black holes collide. But space remains a realm of the unknown. Writing in the journal Nature on Thursday, scientists in Canada reported the detection of mysterious radio signals from halfway across the universe. It is only the second time that repeating fast radio bursts, or FRBs, have been spotted. Astronomers have yet to formulate a full theory of what produces these enigmatic, rapid-fire beams of electromagnetic waves. And in the absence of a firm explanation, speculation has fallen, perhaps inevitably, on alien civilisations. Avi Loeb, a Harvard astronomer, has proposed that FRBs might be powerful energy beams used to propel alien spacecraft. It is not the first time that poorly-understood cosmic phenomena have been ascribed to industrious extraterrestrials. When in 2015 astronomers noticed a star, 1,500 light years distant, dimming and brightening, researchers suggested an “alien megastructure” might be revolving around it, and collecting energy for its constructors. Then, in 2017, the massive cigar-shaped ‘Oumuamua barrelled into the solar system, the first interstellar object known to do so, and prompted speculation that it was a tumbling spacecraft. Chris French, head of the Anomalistic Psychology Research Unit at Goldsmiths, University of London, said it was natural for humans to see aliens behind every cosmic mystery. “We have what is called an intentionality bias,” he said. “It’s the assumption that whenever something happens, something or someone made it happen for a reason. In the context of space, that someone is always going to be aliens.” The evolutionary argument for intentionality bias, or “agenticity”, is that our ancient ancestors fared better if a rustle in the bushes made them run for cover rather than assume it was the wind. “At the end of the day, our brains evolved to keep us alive rather than apprehend the truth of the universe,” said French. The late astronomer Carl Sagan spotted the dilemma for scientists. They can become cranks if they are too open-minded, but may miss out on landmark discoveries if they are not open-minded enough. “It seems to me what is called for is an exquisite balance between two conflicting needs,” he said. “The most sceptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas.” Duncan Lorimer, an astrophysicist at West Virginia University, discovered the first FRB in 2007. When his team spotted the radio burst, the possibility of it being a message from ET certainly came up. “We absolutely thought about aliens,” he said. “We only had the one object. We looked for patterns in the signal and couldn’t find anything, but we definitely considered it.” Now, mention of aliens is beginning to wear thin. “It helps to sell the story, but at this point I do roll my eyes a bit,” he said. Many astronomers now favour the idea that FRBs are intense beams of radiation shed by charged particles as they are whipped around by strongly magnetised neutron stars. “It seems like a more plausible idea, but I don’t want to rule out aliens completely,” he said. “I’ve been wrong before.”

How does the universe work? How does the universe work? Understanding the universe's birth and its ultimate fate are essential first steps to unveil the mechanisms of how it works. This, in turn, requires knowledge of its history, which started with the Big Bang. Previous NASA investigations with the Cosmic Microwave Background Explorer (COBE) and the Wilkinson Microwave Anisotropy Probe (WMAP) have measured the radiation from the universe when it was only 300,000 years old, confirming theoretical models of its early evolution. With its improved sensitivity and resolution, ESA's Planck observatory probed the long wavelength sky to new depths during its 2-year survey, providing stringent new constraints on the physics of the first few moments of the universe. Moreover, the possible detection and investigation of the so-called B-mode polarization pattern on the Cosmic Microwave Background (CMB) impressed by gravitational waves during those initial instants will provide clues for how the large-scale structures we observe today came to be. Observations with the Hubble Space Telescope and other observatories showed that the universe is expanding at an ever-increasing rate, implying that some day - in the very distant future - anyone looking at the night sky would see only our Galaxy and its stars. The billions of other galaxies will have receded beyond detection by these future observers. The origin of the force that is pushing the universe apart is a mystery, and astronomers refer to it simply as "dark energy". This new, unknown component, which comprises ~68% of the matter-energy content of the universe, will determine the ultimate fate of all. Determining the nature of dark energy, its possible history over cosmic time, is perhaps the most important quest of astronomy for the next decade and lies at the intersection of cosmology, astrophysics, and fundamental physics. Knowing how the laws of physics behave at the extremes of space and time, near a black hole or a neutron star, is also an important piece of the puzzle we must obtain if we are to understand how the universe works. Current observatories operating at X-ray and gamma-ray energies, such as the Chandra X-ray Observatory, NuSTAR, Fermi Gamma-ray Space Telescope, and ESA's XMM-Newton, are producing a wealth of information on the conditions of matter near compact sources, in extreme gravity fields unattainable on Earth.

Domination Factories of China - Full Documentary In 2010, China just barely edged out the United States as the world's top manufacturer by output -- a distinction it hadn't held since 1850. Still the two countries were basically neck and neck. No longer. The United Nations has updated its national accounts data to capture 2011, and thanks to China's breakneck growth, its manufacturing output is now leaving ours in a cloud of coal dust, as shown in this graph from AEI's Mark Perry. China's trend line is practically an asymptote. The chart tracks the combined category of manufacturing, mining, and utilities because the U.N. didn't track manufacturing alone for China until 2004. That said, they're beating us on the solo category too, $2.3 trillion of output versus $1.9. As a point of pride, this might all be a bit of a blow for the United States. As an economic issue, though, it's not really so terrible.Yes, we envy China's factory and export engine, but we still build plenty here. In fact, we're building more than ever, and much of our output consists of extraordinarily profitable, technologically advanced products like aircraft that China has yet to master. And, though it's sometimes easy to forget with all the talk of China rising, we're also, well, richer. America's household consumption alone generated $10.7 trillion of economic activity in 2011 -- $3.5 trillion more than China's entire gross domestic product. This, despite the fact that our population is one quarter the size. We might not be the world's top builders anymore, but our economy's bias towards spending does insulate it a bit from the rest world's economic problems, something China's policy makers almost certainly envy themselves.
