Is time travel possible?

Answer 1

Time Is One-Directional. Though time is universal, no man living is able to say what it is. It is as unfathomable as space. No one can explain where the stream of time began or where it is flowing. These things belong to the limitless knowledge of Jehovah, who is described as being God “from time indefinite to time indefinite.”—Ps. 90:2.

Answer 2

Time travel is sort of possible is a sense that we are getting closer and closer to the future as each second passes.

You could travel backwards and forewards in a sense by travel from one time zone to the other so you could repeat the same time again, but techinally it doesn't really count.

If you go on a concord (quite a fast plane, which is now deconmissioned due to sound polltion) , which is darn quick you could theoritily repeat the day for real, but it was never tested or at least the results were never released to the public.

As you may have realised I not very good at explaining about time travel in written form, but I can refer you to a very good book if you are interested but just a beginner: Introducing Time, Craig Callender & Ralph Edney, (Icon Book Uk & Totem Books USA, 2002).

Answer 3

yes. no.

the answer is definitely yes IF there exists an exotic form of matter with something called "negative gravitational mass".
so. you know how all masses attract each other? if there was a kind of matter whose mass had a negative sign (whatever that means), we'd certainly be able to do it!

several ways have been postulated.

If a person could travel faster than the speed of light, they'd be able to follow a convoluted set of accelerations and decelerations which (although his watch would advance a day or two in the process) would carry her to a time "before" she set out. Although relativity says that nothing can travel faster than the speed of light, if we had and could harness this "negative mass", we'd be able to make something equivalent to a "moving sidewalk" in spacetime which would carry us away from where we started at a speed "faster" than the speed of light.

alternatively, if we had a wormhole, we could move the mouths of it around in such a way that it gave people in the "future" a literal door to their "past". to hold such a wormhole open, however, requires more of this "negative mass" stuff.

the moral of the story: if we could get our hands on some of this negative mass, we could do it.

too bad no one has ever touched, seen, or verified the existence of the stuff. it probably doesn't exist.

so... the answer is yes. but probably no.

Answer 4

Time is the expansion of matter through space...
We can only travel into the future, one moment at a time...
Traveling into the past, is like trying to put toothpaste back into the tube...

That's not the way time flows!

Answer 5

It is possible, but almost impossible to do. you see:

To travel through time, you would have to be moving at the speed of light or faster but the only place you can go is backwards, you cannot go into the future because the future is not determinable.

Answer 6

You are travelling through time right now.

And the faster you travel the slower you move through time relative to others.

But you cannot visit the past. Visiting the future is theoretically possible though. But you cant return to your own time.

Answer 7

No, because there is nowhere to go. Time is not a dimension, because it has no extension. There is no future out there waiting for us; time comes into existence each minute and then ceases to exist when it becomes the past. If length were like the pseudo-dimension time, you would have no destination because wherever you were going would not be there until you got there.

Answer 8

Sometimes. According to Albert Einstien's theory,

E = m*c*c

Answer 9

I wish i knew. if i did i'd probably get the Nobel prize or somethin.

Answer 10

Theoretically, yes.
