Well as Steven Hawking says, no one from the future traveling back in time to contact us pretty much proves that time travel is never invented, however it could be that they never visited our time. Some believe it's possible and some believe only the present exists. I don't know much about the subject so I'll post my real opinion after I do some reading .
Time travel is possible. It's just that to do it and have a serious effect revolves around sitting next to or inside a black hole. So even if you were able to travel back in time you'd be dead so fast you wouldn't be able to use the knowledge. That and your trapped in a black hole so you'll see the universe flash past you from the perspective of the black hole. All you'd see was the void of space.
About the Stephen Hawking thing and visiting the past. It is possible that they have but we don't know because they changed an event which caused all of human history to change. That however is flawed by the fact that if they changed something, their time line would cease to exist and if they never existed they could never have made the change in the first place.
Basically it is possible but it's so damn confusing and intangible that it will probably never happen and if it did we wouldn't know that it did.
I do not think Time travel will ever happen. If you do have to move at the speed of light to time travel. We are VERY far from being able to because you would have to create some material that could withstand the speed of light.
Plus, your body would most likely be ripped to tiny particles first like in a black hole so..........
It will never Happen.
Btw, I did not read up on this, this is just theories and my opinion, so if I am wrong about the black hole thing, oh well.
It's only possible if you believe in destiny. Perhaps everything is already predetermined.
Besides, you can easily travel forward in time simply by moving very very fast for a long time.
That made me think of something......Is time even real? The human race created it as a way to tells the beginning & end of a day. So........is Time really just a tool for the human race?
Time travel is easily possible, traveling BACK in time is not.
What has already happened has already happened and it's impossible to change something that no longer exists (the past).
Very true It would be possible to go into the future but getting back would be impossible.. maybe. One thing I do know is that going back in time to change something is either impossible or would be really stupid. Due to the fact that you would go back (say to stop an assassination) you would go back and stop the person from dying.
Then they didn't die, which mens that you never would have gone back to stop them from dying. Which means you WOULD go back to save the person then repeat repeat repeat on and on for all "time". Or that may create a time paradox so that time unravels then we're ALL really screwed.
So (important lesson) if you get the opportunity to go back in time, DON'T CHANGE ANYTHING!!! or else you may either get stuck in an infinite time loop or you'll destroy the universe. No pressure.
Then here's one. When is the present ? Are we in the present or are we really in the past, and if we are in the present what happens if someone goes in the past then are they actually in the present or are they in the past? What defines the "present"?
I remember reading once that any time machine would be able to only go back in time and only to go back as far as when it was created. For example if I made a time machine in 2008, in 2010 I could go back to 2008, but no further back. Explains why theres no visitors from the future.

That's a very good theory. It makes a lot of sense, since time machines travelling back in time don't actualy move in terms of space. But still, how can there be a set time for when the machine was created? Like the moment the parts were put together, or when the machine itself started to function? Or maybe when the idea was actually conceived? It's impossible to say exactly when the machine was created. And technically, if that were true, then the moment the machine was conceived, another one would spontaneously appear from the future, in the EXACT SAME PLACE AS THE FIRST MACHINE and space would collapse, since there are two masses of matter existing at the same place on the same plane at the same time. And that would really suck. Unless, the universe, seeking to save itself, created a second plane and placed the machine there. So it's like on a plane we can't see, but it still exists.
Hmm well I suppose the machine being able to physically exist in the same place at the same time depends on if you buy into the many-worlds theory. As in every possibility that could have and could happen did and does. If that were the case the machine could exist in one or more of our possible futures? Then it could exist as potential?

Wait how would that work? Do you mean like a teleporter that has to have a receiver to go to and in this case it would be the receiver?
No I mean to use the time machine it has to exist in all time you want to travel to, you can't send it back. Only keep it in existence and use it in the times in which it exists. this is assuming the past isn't just potential and really exists.
if a time machine was made ..having the power to rip the fabric of time as we know it anyone who first thought of being able time travel would instantly have the machine as they thought of building it . also wouldnt time travel be just infinite knowledge rather that a machine , if you knew all that would happen in the future i think you could be 'in' every time. saying though that are bodies are just looking glasses on the universe while our 'being' is omnipresent and we are just bound to the body in a certain time . but if we could sever the tie between our current body and take another from the future or past. maybe using the other unused percentage of our brains we could do that

Or, according to Stephen Kings, we could gain psionic powers.
But yeah, I didn't get most of that stuff, but I think that would only work if you were like, a spiritual kind of person. I'm not. =/

WOW.....
That last part's a new one.
This is why I like to talk to people about this stuff. I like to hear new opinions on it.
Time travel... Is it possible?
