Is it truly possible that we can travel back in time?
I also heard that time travel might only be possible through a wormhole. What do you know about that?
Yes, some physicists have hypothesized that traversable wormholes could be used to create a sort of time machine. However, wormholes are purely theoretical objects and have never been observed in nature, so it's unclear whether they really exist at all. Additionally, even if they do exist, it would be extremely difficult to create and stabilize a wormhole long enough to enable time travel.
