Link to Throuh the wormhole: 3- Is time travel possible? documentary
Documentary Description
Einstein's Theory of Relativity says that time travel is perfectly
possible — if you're going forward. Finding a way to travel backwards
requires breaking the speed of light, which so far seems impossible.
But now, strange-but-true phenomena such as quantum nonlocality, where
particles instantly teleport across vast distances, may give us a way to
make the dream of traveling back and forth through time a reality. Step
into a time machine and rewrite history, bring loved ones back to life,
control our destinies. But if we succeed, what are the consequences of
such freedom? Will we get trapped in a plethora of paradoxes and
multiple universes that will destroy the fabric of the universe?
