Time travel though black hole, most of people believe time travel is possible through black hole. I don’t know why most of people interested in watching frictional time travelled movies like Star Trek movie. In this movie, Mr. Spark did time travel through black hole, i mean old spark and meets Jim. The logic behind the scene black hole can mediate as time travel. Have a few doubts before conclusion what if black hole is the last stage of ending star or massive Energy eater that pulls in energy surrounded by black hole. Can anyone approach that kind of situation and be alive even after that. Believe me no, it’s not what you think.
Have you ever heard that ‘Einstein’s theory of relativity‘. Let me show you the video of below what is time? and how it works explained by Albert Einstein’s movie.
There are always number of theories like Wormhole based on Einstein’s general theory of relativity. Most of movie authors, directors like to use Wormhole in their movies but believe me they never seen wormhole before. If wormhole exists, it is used for time travel like shortcut to travel to past or future.
In Conclusion, the time travel is possible if wormhole or time medium really exists. But in reality, it is hypo theory that is like imaginary until it proves by scientifically.
