Mathematically it seems that if you had an infinitely long rotating cylinder (which is itself impossible) then there might be some curved timelike paths through the space near the cylinder.
Realistically speaking, time travel is not possible, except the normal way: into the future at one second per second.
Einstein theorized that it was possible to travel into the future by going near the speed of light, but said time travel to the past was impossible.
Yes it is possible. If you orbit a black hole a bit away from the event horizon in the speed of light then your movement in the time axis will be drastically slowed down with respect to the rest of the universe. Suppose you keep doing this for about a week and return to Earth. You would be baffled to see that the earth has probably aged a 1000 years or even more. Or maybe there is no Earth to return to.

Yes, it is possible...but only if we can build a machine that can accelerate and reach the speed of almost the speed of light (the cosmic speed limit)...unfortunately, such a technology is still a long shot as people, enterprises, and even the governments are focusing on doing something else.
We do not have the technology to make time travel possible and probably will never have such technology. Too many resources are being used fighting wars all over the world.
After my opinion this is only a phantasy.
Time travel is not possible, so it's not dangerous at all.
Yes, it was.
There is currently no know and confirmed way to travel in time.
It Could Depend. But it could be possible.
it's not possible..
i think because time travel may be possible scienctist can
no. the reason it is impossible is because there is no way to bend time, and even if that were possible, it would not be possible to bend it back far enough. i think there's a good reason that time travel isn't possible. if it were, we would change time (not good). and we would look forward to see what will happen and it will affect our decisions (also not good).
There is no evidence that what is commonly known as "time travel" is possible at all.
He believes it is possible to travel back in time due to the effects gravity has on time. Time slows down due to a strong gravitational pull, and time speeds up in gravity-free space.
Time travel is not possible, so it's not dangerous at all.
No,time travel is possible but it is somewhat difficult,as einstein said,"if an object travels with speed of light , the time near it would become slow and time travel wold be possible. All we need to is to produce such machine /spaceships that can travel up-to light's speed.
no, time travel is not possible so there is nothing to study
Yes, it was.
No
It is not possile to time travel, nor will it be in the near future.
Time travel is not practically possible no matter what your start point or destination.
Basically, it isn't known whether time travel is at all possible.
