Through The Wormhole: Is Time Travel Possible?

Theory of Relativity says that time travel is perfectly possible – if you go forward. Finding a way to travel back requires breaking the speed of light, which so far seems impossible. But now, strange but true phenomena like quantum non-locality, where the particles to teleport instantly across great distances, can give us a way to realize the dream of traveling back and forth through time in a reality . Enter a time machine and rewrite history, bring loved ones back to life, control our destinies.
But if we succeed, what are the consequences of that freedom? Let’s get caught up in a lot of paradoxes and multiple universes that will destroy the fabric of the universe? Einstein said that nothing travels faster than the speed of light, but when physicists see how entangled particles behave, they get stuck in a mirror in which this principle does not seem right.
Physicists do not fully understand entanglement, beyond which is a relationship between the particles. If you want to know what mess looks like, pull up a chair to an experiment that has occurred. Researchers at the University of Nice-Sophia Antipolis and the University of Geneva, shone a laser made of photons, the basic units of light in the glass. When photons hit the irregularities in the laser crystal, single photons are sometimes divided into two. These photons daughter were related to each other and their parents of photons, in the amount of energy they had.
You can think about the photon father is like a train, and the glass as many potholes. When the train hit the pothole, broke into two strings of cars related to the directions and speeds. These daughter photons were not only related, but intertwined. The particles are entangled they are related to a property, but the rest randomly.
This is the third episode. See the list of all the episodes here: through the hole.
