has time-travel been discovered, is it working?

[iatemyhandoff]

is there a present time travel mechanism that works, if not, have scientists figured out how to time travel and are working on it

Send an email to NASA and see if they think time travelwill ever be feasible.

Einstein's General Theory of Relativity allows the possibility that a practical time machine might be built. Such a machine would need to be able to create and manipulate black holes, and the technology needed for it is far more advanced than anything humanity might devise for hundreds or even thousands of years.

Oh, yes it does. I just got back from 2042. Awesome.

Close your eyes for one minute. Poof, you've traveled one minute into the future. You can change the amount of time you want to go into the future by altering how long you shut your eyes.

Oh, btw, you don't really need to shut your eyes if you don't want to.

I could answer you but then I'd have to... ! I'm sure someone is. Our thirst for knowledge as humans leads us in that direction. A time-spacecraft is feasible according to physics. What is a potential barrier is that its use may alter histories. But if you accept the multiple history theory from A Briefer History of Time then it is possible and has happened as well as in another history has not happened yet and in another never will and so on and so on.

Why yes, haven't you been watching the news lately? A bunch of scientists went back to the Cretaceous era to do a bit of dinosaur safari. I'm surprised you haven't heard about it already.

No, No and Yes.

As your velocity relative to earth approaches the speed of light in a vacuum (<i>c</i>), you begin to experience time dialation with respect to earth. In what you perceive as one second, those of us still travelling the same velocity as Earth will experience much more time. You can use this to travel into the future.

The downside is, this method provides no way back.

facepalm

If you would like a lot more answers, put 'time travel' in the search bar above in the green strip. A lot of people have asked this before, so you may be interested to see the answers they got besides the ones you get.
