Time travel is possible. In fact, in two different ways. At least that’s what Brian Greene, a physics professor at the renowned Columbia University in New York, believes. At the “World Science Festival” he explained how trips through time could work.
New York – Brian Greene is Professor of Physics and Mathematics at Columbia University. At the “World Science Festival”, which he co-founded, the 58-year-old American brought his audience up to date with the latest scientific developments on movements through time. The most popular question in this regard, whether time travel is possible, Greene answered with a resounding yes.
According to Greene, there are exactly two ways to travel through time that are fundamentally different from each other. The journey into the future is one of them and the one that numerous scientists believe should actually be feasible. Over 100 years ago, Albert Einstein showed mankind how time travel works, says Professor Greene, and is astonished that people know next to nothing about it.
Traveling to the future? Definitely possible.
According to Einstein’s account, the process works as follows: A person goes into space and moves there at almost the speed of light, turns around and returns to earth, whereby the person’s clock would now tick more slowly. With that the person would have traveled to the future on earth.
In addition, Einstein showed that staying near a strong gravitational source, for example a black hole *, and approaching the edge of this object would cause the time for this person to be greatly slowed down compared to everyone else. Back on earth, it would also be another visit in the future.
According to Greene, many scientists who are familiar with this matter would agree with the findings of the German physicist icon. The other type of time travel, the passage into the past, is the one that causes heated discussions. Because unlike traveling into the future, many physicists do not believe that time travel into the past is possible.
Some others do not rule out this option completely and instead use the so-called wormhole theory, which was also formulated by Albert Einstein. “A wormhole is like a tunnel through the Swiss Alps: Instead of walking long stretches on the mountainous surface, you can shorten the route through a tunnel,” Greene tried to illustrate the topic in an interview with the world 20 years ago.
Einstein’s theory now states that manipulating the opening of a wormhole means that time does not pass at the same pace at both ends. Thus, when crossing this tunnel one would not get from one place in space * to another place, but from one moment in time to another moment. The future would lie in one direction and the past in the other.
“We don’t know if wormholes are real. If so, we don’t know if you can really walk through it, ”says Greene. So there are numerous imponderables. Since Einstein’s ideas are in harmony with the laws of physics, the theory has not yet been rejected. On the contrary, according to Greene, even the US Pentagon has been researching wormholes for decades. * Merkur.de is an offer from IPPEN.MEDIA
