So far, time travel has not been achieved - not with a watch, not with any other device. It seems somewhat doubtful that it ever will be possible.
No, there isn't another piece of the time travel watch.
Some theories suggest it may be possible, others deny it.
He believed that, in theory it could be possible to travel backward in time, but he did not make a machine to conduct time travel
There is no evidence that what is commonly known as "time travel" is possible at all.
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).
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
No
No, it is not possible to obtain a patent for a device that enables time travel as time travel is currently considered a theoretical concept and not a practical invention.
No. Not even manga artist can travel back in time the 220+ years necessary to make that possible.
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.
