as to the original comment to this question, "Yes of corse it is they did it in Star Trek. live long and prosper", this is not Science Fiction. we dont want crap answers that deal with TV. the theory of time travel is actual physics. not just something that they do on TV or in movies.plus they never have time dialation when they "go back". technically, if you time travel, the person time taveling will get younger and travel into his or her past, while going into the future.
There is no evidence that what is commonly known as "time travel" is possible 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
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.
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.
There is currently no know and confirmed way to travel in time.
Basically, it isn't known whether time travel is at all possible.
You mean risking your life being stuck in something, million miles away from earth, because the earth is obviously not at the same position as it was when you was about to time travel? So is time travel possible?: maybe.
Time travel is possible. You can build a time machine with 10 million USD.
theoretically its possible..but were not even close yet
