What were to happen if we could successfully go back and alter the past? What consequences would take place? + + + + + + + + Previous Episode: Can We Actually Time Travel? Einstein Says 'Ja!': https://www.youtube.com/watch?v=jvKdgqxDQ2U + + + + + + + + Time Travel Paradoxes: http://science.howstuffworks.com/science-vs-myth/everyday-myths/time-travel6.htm "As we mentioned before, the concept of traveling into the past becomes a bit murky the second causality rears its head. Cause comes before effect, at least in this universe, which manages to muck up even the best-laid time traveling plans." The Grandfather Paradox: http://timetravelphilosophy.net/topics/grandfather/ "Tim hates Grandfather. Tim hates him so much that his ambition is to murder Grandfather despite the fact that Grandfather is already dead: he died in his sleep in 1957. Tim is no quitter, however, so he builds a time machine and travels back to the year 1920, a time before Grandfather's death." Time Travel Simulation Resolves "Grandfather Paradox": http://www.scientificamerican.com/article/time-travel-simulation-resolves-grandfather-paradox/ "What would happen to you if you went back in time and killed your grandfather? A model using photons reveals that quantum mechanics can solve the quandary-and even foil quantum cryptography." The Butterfly Effect: http://www.stsci.edu/~lbradley/seminar/butterfly.html "Weather prediction is an extremely difficult problem. Meteorologists can predict the weather for short periods of time, a couple days at most, but beyond that predictions are generally poor." Definition of butterfly effect: http://www.merriam-webster.com/dictionary/butterfly%20effect "a property of chaotic systems (as the atmosphere) by which small changes in initial conditions can lead to large-scale and unpredictable variation in the future state of the system" Does God play Dice?: http://www.hawking.org.uk/does-god-play-dice.html "This lecture is the intellectual property of Professor S.W.Hawking. You may not reproduce, edit, translate, distribute, publish or host this document in any way with out the permission of Professor Hawking." 10 Mind-Boggling Paradoxes: http://mentalfloss.com/article/59040/10-mind-boggling-paradoxes "A paradox is a statement or problem that either appears to produce two entirely contradictory (yet possible) outcomes, or provides proof for something that goes against what we intuitively expect." 5 Bizarre Paradoxes Of Time Travel Explained: http://www.astronomytrek.com/5-bizarre-paradoxes-of-time-travel-explained/ "There is nothing in Einstein's theories of relativity to rule out time travel, although the very notion of traveling to the past violates one of the most fundamental premises of physics, that of causality. With the laws of cause and effect out the window," PARADOXES: http://space---time.blogspot.com/ "Temporal paradox (also known as time paradox and time travel paradox) is a theoretical, paradoxical situation that occurs with time travel into the past. These include: thebootstrap paradox, predestination paradox, and grandfather paradox." + + + + + + + + DNews Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love.
