Zapping to your past might be possible
Though hypothetical but baby steps to understand time and time travel were taken back during Einstein’s era. Time and the speed of light. Relating these two one can travel through time under special conditions only. Time tourism exists in many myths also like in Mahabharata (Related to Revati who is considered to be the time traveler in Mahabharata). Apart from this many theories exists on how one can travel in time and even why one can’t. Using wormholes, traveling faster than light are the theories used in Hollywood movies DeJa-vu and also in many such sci-fictional movies. Time travel demonstration here is like the one from movie Interstellar (just relatively ) where the time is shown to be running slow and thus affects the aging of the explorers.
Professor Brian Cox – a confirmed Doctor Who fan – undertakes an experiment with a light showing that time moves faster for a stationary clock than a moving clock, which appears to move more slowly over the same length of time. His conclusion is that time travel is possible, but only into the future!
