Question: Could time travel ever be possible?

Caroline Roche answered on 19 Dec 2024:

Yes. It is possible to travel into the future, if you leave earth and travel at the speed of light, time will pass slower for you than those on earth. So that when you return you are now in earths future compared to when you left.
It is a bit trickier to travel into the past (possibly even impossible) and one that people aren’t sure how to do. It also raises lots of questions on what happens when you go back and you change something i.e. does it affect the future you’ve come from or does it just generate a new timeline, can you ever return to your original time.
