Traveling in time has fascinated people for hundreds of years. Scientists know a few ways to do it



It is very important that you realize that there are two kinds of travel in time and they are radically different. "We know how to do it because Einstein showed us the way a hundred years ago," said Brian Greene, a professor of physics and mathematics at Columbia University. It is surprising how few people yet know this theory and is convinced that it is possible to bruise it. Einstein showed that if we go into space and travel at a speed close to the speed of light, we will return in time and time on the clock will change more slowly. So when we come back, time on Earth will be a future.

Einstein also showed that if we get close to a strong source of gravity – neutron stars, black holes – and go to the edge of this object, time will slow down for a particular person. Therefore, when we return to Earth, the future will be far away.

This theory is not a controversial thing at all. "Every physicist who knows what he is talking to agrees," said to futurism.com Brian Greene. However, traveling back in time, or in the past, does not seem real. Many scientists exclude his possibility. The phenomenon that people at the very least think is worth watching when traveling to the past is "wormhole ". And it was Albert Einstein again, who discovered the wormhole.

A wormhole is a bridge or a tunnel where you can get from one place to another. They discovered it in 1935, but then realized that if we manipulate the wormhole holes – we place it near the black hole – then the time of the two holes in that tunnel will not run the same way. So one can not get to another place, but also in another time. This could mean that one way will be to travel to the past and to the future in the future.

However, for clarification, scientists do not know for sure the existence of wormholes. Thus, it is neither possible nor realistic to confirm whether these tunnels would really work to move in time and space.
