1. • • Although many people are fascinated by the idea of changing the past or seeing the future before it's due, no person has ever demonstrated the kind of back-and-forth time travel seen in science fiction or proposed a method of sending a person through significant periods of time that wouldn't destroy them on the way.

   Is time travel possible in science fiction?

   • As often portrayed in science fiction, with a time machine, nothing is permanent anymore — you can always go back and change it. But is time travel really possible in our universe, or is it just science fiction? Our modern understanding of time and causality comes from general relativity.

   Can time travel?

   • The second law of thermodynamics suggests time can only move forward, while Einstein’s theory of relativity shows time’s relativity to speed. Theoretical ideas like wormholes offer potential methods, but practical challenges and paradoxes, such as the “grandfather paradox,” complicate the feasibility of actual time travel.

   What if time travel were possible?

   • If time travel were possible, it would mean the existence of parallel timelines. (Shutterstock) Have you ever made a mistake that you wish you could undo? Correcting past mistakes is one of the reasons we find the concept of time travel so fascinating.

   Can physicists find out if time travel is possible?

   • This theory has existed for more than 100 years, and has been experimentally verified to extremely high precision, so physicists are fairly certain it provides an accurate description of the causal structure of our universe. For decades, physicists have been trying to use general relativity to figure out if time travel is possible.

   Can physics explain time travel?

   • It turns out that you can write down equations that describe time travel and are fully compatible and consistent with relativity. But physics is not mathematics, and equations are meaningless if they do not correspond to anything in reality. There are two main issues which make us think these equations may be unrealistic.

   Is time travel a fun idea for movies?

   • Time travel is the concept of moving between different points in time, just like you move between different places. In movies, you might have seen characters using special machines, magical devices or even hopping into a futuristic car to travel backward or forward in time. But is this just a fun idea for movies, or could it really happen?

   Nov 17, 2023 · Time is relative. However, physicist Albert Einstein’s theory of special relativity suggests that time passes at different rates for different people. Someone speeding along on a spaceship moving close to the speed of light – 671 million miles per hour! – will experience time slower than a person on Earth.
