Time Travel - Is it possible...?

[Borincano]

Do you think time travel is possible? I've read that nothing in Einstein's theory of relativity says it isn't. I also read that the universe just might be a copy of itself, with many worlds just like Earth with the same people and events. Therefore, time travel would just be going into those other worlds and any event alterations would just occur in that world and would not effect ours. However, that would effect the order of things and the universe would no longer be an exact copy of itself. What do you think? I think time is just an illusion.

It's fun to think about it.

I think if it was possible to do so as a physical being then life wouldn't exist. There'd be someone who would go back and stop the earth from developing or something like that. The logistical nightmare for us to have gotten this far would need 100 earths to complete.

I imagine time travel of a different sort. Perhaps capturing the light rays from thousands of years ago and tracing them back to view the world as it once was.

More interesting to me personally is the notion that time flows backwards and we are the subconcious of our subconcious. Growing out from the earth then flowing into our parents until finally...zip game over.

MJM,

Interesting input. Watching the latest movie of the "The Time Machine" a few nights ago and reading a website about time travel, made me want to post a thread here on the subject. Here's the website: Time Travel (http://www.biols.susx.ac.uk/home/John_Gribbin/timetrav.htm)

of course it isn't possible. And we know this because nobody has come back in time yet. Just like Steven Hawkings said.

According to nuclear physicists the answer is a resounding maybe.

it may be possible to go to the future though but we havent figured a way to go faster than the spend of light.

when you look in the sky you're seeing the past.

30, 40, 100+ years ago... who knows how many of those objects are still in existance. For all we know, the stars that created the belt of Orion could have been destroyed a few years back.

It's kinda interesting when you think about it like that.

But anyways, yeah I think it's possible that travel might be possible. Of course this is just a hypothosis, cause realistically we don't know exactly WHAT time is.

Everything is in the NOW... is it not? =/ puzzling, astronomy and physics is...

its interesting to think about. you can then expand from thinking of time travel, to the concept of fate.
is everything fore ordained? do we have control over every little aspect of our lives, in fact is there any part of our lives that we actually can control.

time travel....well i dont think we will ever know, it will plague everyone minds.

of course you have then try and realize the concept of TIME itself. what is time? is it simply the creation of the past....?

i think my head will explode if i think about it too much.

Time is just movement of matter(think about it, without matter in a space how can it changeover time?), if we can somehow find a record of how every single atom in the universe is at a particular time then maybe we could do some shit...

[lostone]

well, every time you look at the night sky you are "travelling" millions of years straight to the past, but if we exit from this kind of view i think that it's not gonna happen soon...
and travel to the future, well, we're all going straight there aren't we ?
it's interesting to see how simple philosophical question becomes complicated physycal one... something nice to think about...

[Nateddi]

this is a very interesting theory i would love to read up on sometime.

ive always been an admirer of einstein, but i never bothered to read any of his writings. does anyone know where i can get a studyguide to the theory of relativity?

[bluerev002]

i dunno, i mean i thinkg that time travel is not possible.

i think that time IS a continueum, saying that it continues in one direction and cant be repeated. so we cant go backwards, fowards, i doubt that one too. but hey anything IS possible, and it is a mamals own instincs to try and think of new things.


i like what Iepelei said how we are looking into the past.
like when we see a super nova, i didnt happen that instant, it happend millions maybe even billions of years ago. if the sun exploded, we might not know it till 8 minutes after it exploded. no wait, we would cuz the blast would totally blow us away.

AH IT MAKES ME HEAD HURT!!!

[IHP]

Ian Rocks,

thats a good answer, but is it as simple as that? is it just movement of matter? why and how is it regulated. why do humans change, and are we advancing. does time exist, or did we create the concept of time to mark to movement of matter? are we staying still but constantly changing?

I am not sure. Too many paradoxes. For example; say you build a time machine to go back and kill Hitler. It wouldn't work. If hitler was dead; then you would have never been inspired to build a time machine to go back and kill him.

[man in the red suit]

good point Drake. That is my other new proof for not being able to travel back in time. I have 2 arguments now; yours and mine. :)

[Lardlad95]

We are already traveling through time, we are traveling forwward

the trick is moving backword

however I feel it is possible i mean time is a dimesnion and you can move through different dimesnions
