Can we time travel?
We know that mass slows down the flow of time. So we experience a slower time rate compared to the moon. With that being said, time is not a permanent thing. As we explore our universe and move outwards from Earth, we can no longer use Earth time because that would be incorrect. Let say we have advanced enough to have space stations near Jupiter or Saturn. Each clock would run at a difference rate.
So if we can change the flow of time, does that mean we can travel through time at different rates and thus time travel?
This is much different than the science fiction time travel where one would open a gate and travel back in time (Back to the Future). For that I do not think it is possible because we would have been visited by beings from the future already.

Your time travel question always gets me thinking too I've had long discussions with my popz about it...let me get back to you tomrrow when my brain is more fresh
personally, i think other lifeforms exist, the universe is too big not to, and to be visited, maybe the govt knows and its hiding it from everyone :D
Haven't you see Twelve Monkeys?
hmm.. i don't have a lot to say about time travel.. other than if it's possible.. i would like give it a shot.. =) there are definitely places of the past i would like to see first hand with my own eyes..
It has been postulated that because spacetime is warped and not flat, that you could tear its fabric, so to speak, and open a connection between you and a point in the future or the past - i.e. a wormhole.
It's theoretically possible (and in fact, very doable) to move into the future at an accelerated rate through relativistic effects.
The question of moving into the past is another issue altogether, and it has been hypothesized that a wormhole that allows time travel would not permit time travel to any moment in time prior to its creation.
:confused: <-- I think I'll leave it at that. Heh.
and then there's star trek's take on this whole time travel/worm hole thing... :confused:
I guess we'll truely know when we're able to break the light barrier... whenever that's gonna be... ITS UP TO U NUKECHEM!!!!!
Do i seriously sound like a 5 yr old for ppl to start doing that to me? ><
But anyway... now that u mention it... remind me that there are some places and ppl from the past I'd like to see too!!! (and bitch slap while Im there :tongue:)
Take for example if a probe gets pulled into a black hole's gravity field. Because the mass is so great, time is very very very slow. So if we were to view that probe, we would see it "fall" into the blackhole for infinity. That is assuming we could see it which is impossible because there would be no light emitting from the whole for us to see the probe.
Hilarious comedian who would want to do something with time-travel that I would NOT... haha
(that segment is right at the start and then he talks about other stuff)
that's very interesting, so essentially if you can get close enuff towards a black hole, and have some sort of propulsion system to keep you from falling in, essentially you could eventually enter a state of "freeze in time" since you're time would be indefinitely slower than the rest of the universe, and stick around to see the next millenium :smile:
