Re: Timetravel
 

I think time is very much possible, in fact we are able to travel into the future right now, the faster you travel the more forward in time you jump, an example is there are two twin brothers and one of them is an astronaut, now the one that has gone in space because of traveling so fast is now about a second younger than his brother back on Earth, of course to travel any considerable distance forward in time, you would have be traveling much much faster than anything we are capable of now, something like close the speed of light. (Oh and these two brothers are real, Its not a story I made up as an example, one does work at NASA as an astronaut)

Now traveling back in time is a whole other thing, and would be much harder, as of our current knowleged is not quite possible yet. Thought there are many theories, and actually someone attempting it, thought only actually trying to send a particle of light back in time. And there are theories that say that if you did actually manage to travel back in time, you wouldn't actually travel back through time but instead you would enter a parallel dimention where events that occured in your dimention haven't occured yet, so in a sense you are in the past, though in relation to the dimention you came from in terms of events, and you would never be able to return to your own dimention, since if you tried you would only be going forward in time with all the changes that you made in the new dimention you entered, so you would be stuck there, never to return to your orriginal dimention.

Edit: Oh someone just posted about the astronaut right before me, thats what I get for typing for so long ;)

Re: Timetravel
 

I don't think time travel is possible. In fact, I pretty much agree with what FileTrekker posted last. The past has happened, then its been done, and that's the end of it.

The future hasn't happened yet, and isn't happening anywhere else, so it can't be visited.

I do believe thats its possible to recreate time, certainly the past could be recreated, and with enough technology/money/space you could in theory recreate characters and settings from the past, who think the same as their originals, then live in that past and play it out again.

Not ageing by one seccond is not time travel. What you are suggesting would mean there is two of him at once, so there would have been two spaceships at once and so it would have been observeable. Your simply saying the guy did not age.

Sounds fancyful but really it has no basis whatsoever in logic or fact. :uhm:

Re: Timetravel
 

I think you could do the illusion of time travel because if you travelled faster than the speed of light, but if you slow down then you must combust or something. Or would you combust travelling at the speed of light anyway?

Re: Timetravel
 

well.. i dont know if timetravelling will ever be possible, cuz its so strange.. i mean, everything u would do in The Past, would make a whole difference to The Present. And the people living in The Present, would suddenly change? or sth? e.g., if you rescue some1 from being murded in The Past, would he, if you 'flashed' back to The Present, suddenly pop up cuz he is suddenly alive ? its just 2... strange..

i do think however, you can actually slow down time. I once heard something like; if u were in space, travelling w/ the speed of light (or faster), then, time slows down...
So, like (in the future), if we send an Astronaut up in space travelling at the speed of light for a few years, and he would return, like on earth 10 years would have passed; while he was only in space for a few years.. something like that ... it hasnt much use though.. lol..

timetravelling would be really cool though.. u could do everything...
it would also be really scary... for the same reason..

Re: Timetravel
 

It's impossible to really comprehend the implications of going back to the past. It isn't physically possible, even in theoretic physics it isn't unless we somehow muster half the power of the universe to "skip" time, but that ain't happening. I see travelling forwards as possible, but going back isn't.

Re: Timetravel
 

I don't see how going forward in time is really any more possible than going backwards in time. It may be possible (like that astronaut) to travel quicker through time than everyone else, but to travel forwards in time in the sense that you are actually physically moving to a different stage in life as its known, would be impossible.
Moving quicker through time would have no real advantages though, as all you'd be doing would be writing your own "present", not actually going forwards in time at all.

Re: Timetravel
 

:gpost: What I cannot comprehend is - if you've not done it yet, how can you look at it before it happens? What if you change your mind when you go back to the present? I believe it's just as impossible to travel forwards in time as it is backwards.

Re: Timetravel
 

Is'nt this somethign to do with parallel universes (like the string theory etc.) and that everything that could possible happen (infinite things) has already happened in one of the infinite parralel universes.

Now surely there has to be some way of connecting that to time travel into the fuure?

Also:

Is it true that mass cannot travel at the speed of sound? I heard it somewhere but don;t know if its true or not. If so then thats that theory out the window :\

Re: Timetravel
 

Well theoretically speaking, you could probably make a calculation to determine how many seconds/minutes ahead of your own time you want to be once you've finished "time travelling". It is much more possible than going back in time, because to going forwards has already been done, going back is impossible, because there really is no way to turn back time.
The time travelling that has been done, is really only skipping times. Like a minute only lasting 30 seconds. To pinpoint an exact time would be possible, but you'd have to be going very fast.

Parallel universes [if they do exist] would be in time with our own, that's why they're parallel. However things could be completely different.
