Is it possible to travel through time?

Question

rather its black holes or building a time machine will ever time travel to past and future can it be done explain this to me cause i think it's impossible

Answer 1

nono u can't do it ! Just think thats ******* crazy! And if anyone tells u that u can ask them to prove it ... They can't ;)

Answer 2

Right now Scientist are trying to figure out a way to travel though time, future, and back to the past. I would say right now they don't have a way to travel though time. There's really only one way, it would have to be maybe a diffent Dimention, Thats my best guess. If I find out something else that can answer your question in the next three days I'll answer again, if I can. Or, What you said that could also be a way. (Black hole?)    

Answer 3

It is easy to travel to the future.  We do it every day we live.  In fact, I don't know how to NOT do it aside from dieing.

Answer 4

As some said you travel to the future everyday, every second. But into the past is not possible. Now if you have a very fast rocketship in theory you could travel millions or billions of years into the future. But you could never come back to "now".

Answer 5

This site addresses it pretty well:

http://en.wikipedia.org/wiki/Time_travel

I think the short of it is that forward, one way, time travel (if you call it time travel) is possible, but that backward time travel is improbable. As it stands, it is often really backward time travel that catches our imagination. The effect of forward one way time travel, after all, is also expierenced by people who awake from comas.

Einsteins Theory of General relativity leaves the door open for backward time travel in theory, but no meganism for how it might work.Also, that will present the "Grandfather paradox". That is, if you go back and kill your grandfather before your father was conceived, then you would not have been born to be able to travel back in time to kill him. So what "prevents" this from happening? Even for a non violent time traveller, it is difficult for any time traveller, by just being there, to not change the course of history. In weather physics it has been postulated that a butterfly flapping his wings (or not) can lead to a chain of events that determine whether a hurricane develops or not. Therefore any time traveller who breathes and walks where (in the original "set") there had been no-one, will change the future, even drastically. The answer given by some is that any time travel creates a new "parallel" reality, but that opens a pandora's box of other problems. There is no branch of science that is equipped to deal with these questions.

The short is that backwards time travel is probably not possible, but that it makes nice stories.

Answer 6

Yes. We are all doing that right now. We are travelling from past to future.

But besides this standard rate in time travel, we can change this rate by changing our speed as per the equation

T = t / sqrt{1 - v^2/c^2}. where v is the velocity.

Answer 7

besides the obvious answer "yes we're doing it now" I believe that both future and past time travel can be achieved. In relation to Einstein's theory of general relativity, someone traveling at a speed near the speed of light would be traveling through time at a slower rate than those traveling at a normal rate of time. When this light speed traveler slows down to a normal rate of speed while an 1 hour may have passed for him, a day or even a year could have passed for the rest of us, ergo future~ I like to believe if that is possible the opposite could be possible. If moving through space a faster rate can slow time's effects on you than space moving around you at faster than normal rate should speed time's effect on you. Since everything in the universe is moving, your best bet to find the very center of the universe   which may or may not be empty space which everything in the universe revolves around. Keep in mind that the closer you get to the center of the universe the stronger the gravitational force would be and you would be infinitely crushed, but still what if...
