Is backwards time travel possible?

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

How traveling back in time could really physically be possible?

Due to time dilation and length contraction, you might reach your destination in only a year, and then come back in just another year. This is the standard way time travel physically works: it takes you into the future, with the amount of travel forward in time dependent only on your motion through space.

Can we travel in time?

Time is linear – it only goes forward. For that reason, we can only travel into the future, not the past. In fact, astronauts that spent about a year on the International Space Station are now living in the future compared to us. Even though it’s just 13 milliseconds in the future, they are proof that traveling in time is possible.

Is it possible to travel into the past?

For that reason, we can only travel into the future, not the past. In fact, astronauts that spent about a year on the International Space Station are now living in the future compared to us. Even though it’s just 13 milliseconds in the future, they are proof that traveling in time is possible.

Can we detect past time travelers?

Most scientists agree that if time travel were possible, we would be able to detect traces of past time travellers. Time travel is heavily featured in the long-running BBC television program Doctor Who. Doctor Who has been on the air since 1963.

Is time travel possible according to Hawking?

Steven Hawking once claimed time travel was impossible, but later changed his mind. Some scientists theorize that due to the ‘Grandfather Paradox’, time travellers would be unable to change the past without destroying their original future.
