Replying to Time travel.

Do you think humans will ever achieve time travel?

I am really certain that one day we will be able to send people to different stars and maybe even different galaxies in a single lifetime. like travel thousands of light years in a pretty short time. all we need to do is find a way to get a spaceship going fast enough.

So like sending someone into the future is theoretically pretty simple. What is even crazier though is if you think about it, it really is even possible to travel back in time.

That would be so crazy but like what if humans in the future have this technology but just don't want to use it because they don't know what changing stuff would do to them?

Man usually I am so baked when i think about this kinda stuff, but not right now.
