I'm not sure but one thing I'd do is try my best to convince Abe that the play he wants to see sucks ass. There is a brothel in town tho with this lady that does unimaginable things. We should just go take a peek

Most of the comments were actually very enlightening!!!!

It's less a matter of "Is it possible?" and more a matter of "Will we ever have the means to achieve it?".

So what about sending messages from the future to the past.. Stuff like precognition..

Considering the fact that we do not (and may never) really understand the concept of time, no, I do not think we will ever actually be able to time travel. And if sci fi films have taught us anything, it's that it's probably a really horrible idea even if we could.

 Keeping in trend with vgchartz these days simple question is time travel possible? To me if time travel is possible why have we never encountered time travellers, what is stopping them from coming back into the past (our present).   This leaves me to conclude three logical scenarios.

1. Scientist got it wrong and time travel is impossible.

2. Time travel is possible and there are time travellers ,they just keep themselves hidden.

3. The world soon ends so time travel is never invented.

Is there something I am not understaning that someone would like to explain.

Note when I say explain I mean in your own words ,providing links and large quote trees does not show your knowledge on a topic.

Well, presumably you mean travelling backwards in time. Travelling forward it time is possible - we are doing it even right now (it took me a few seconds to write this reply, during which I travelled forward it time by that amount). Modern physics tells us that we can even travel forward in time at different rates (look up the http://en.wikipedia.org/wiki/Twin_paradox).

On the sub-atomic level, things get interesting. According to Feynman's quantum mechanics, anti-matter (which we have observed and can even create and store) is physically identical to normal matter travelling backwards in time. Whether it actually *is* normal matter travelling backwards in time is of course a good question. 

What quantum mechanics tells us is that if time travel backwards in time is possible, it would probably be different from the "Back to the Future" type time travel where you get into some device and exit at some point in the past. It would be more similar to that movie "The curious case of Benjamin Button", where you would meet someone who seems to grow younger and lose knowlegde as time goes by.

Yes but only forwards in time. Meaning it's pretty useless.



Hmm, pie.

Time travel happens all the time. Time is not set in stone. Because of relativity, objects at different relative speeds experience time differently, that's why GPS satellites don't work with ordinary clocks, they need to be adjusted accordingly.

We can travel to the future by approaching the speed of light, that makes our time go at different rates compare to other objects or beings. Light itself doesn't experience time, the moment something makes a photon and the moment that photon becomes something else (heat) are the same very moment from that photon's perspective.

Travelling back in time is another matter though. Perhaps it's theoretically possible when surpassing the speed of light? But that can't be done so I don't think travelling to the past is possible.


Sorry but no. We can live longer by approaching the speed of light relative to people not travelling the speed of light but that doesnt give us the ability to time travel. 
Time is aman made concept, so nothing besides man experiences it. we just relate it to other objects so no light isnt the only thing that doesnt experience time.

We can travel to other people's future, of course it would still be the present for us.

I think if it was possible, i would imagine it like this:
You're in universe A and travel 20 years into the past. As soon as you do you immediately create a new Universe, such as Universe B that would be exactly the same as universe A but would start changing depending on what you did. It would be impossible to return to universe A and every time you time traveled, a new universe would be created. So if you went 5 years into the past of Universe B, you would create Universe C with the changes you made. Completely impossible to return back to the previous universe you traveled from.


I agree. If time travel is possible, it would certainly only be possible in this capacity.

4. Time travel is possible, but our time is not interesting enough, so we don't get any visitors
