Nice... I have been educated :)
Looks like allot of teachers I had were whut tar's (A one winged bird that died out)

So let me get this strait?

People Age Faster in outer space, not not at all.
Thats Interesting... Im interested to know your (Everyones) theroy on time.
My mum belives that Time is an Elusion. If you got to the Crimson Circle Websight you might understand some of her theory. I however, am now unsure of my Theroy of time...

Edit1: Oh yea, I am being Serious

I don't think there is any question that special relativity is the best model of time. It makes predictions that have never been contradicted, and is essential to modern astronomy and related fields like GPS triangulation.

I don't see how a one-dimensional infinitely long train track with time being the train could be affected by gravity, since as far as I know, time doesn't have a physical form that gravity could manipulate.

Oddly enough, if gravity does manipulate time, black holes could possibly be wormholes between universes due to time being distorted to the point of… Something or other. The point is that time would move at an exponentially increasing rate, possibly reaching infinity times infinity or something crazy like that. (Now aren't we glad that the universe isn't a computer? It'd have crashed so many times trying to compute infinity if it was.)

In other news, BRAIN… HURT! *ker-thump*

On the other hand, who gives a shit?

Lot of pseudo-intellectuality going on here.

People who aren't you, obviously. Well, some people who aren't you anyway.

Gravity is not a force according to the general theory of relativity; it is a curvature in spacetime. I don't remember my astrophysics class well enough to explain clearly why it works, but I think the time dilation is caused by acceleration, of which gravity is a special case. There have been tests with atomic clocks at different altitudes, and with different acceleration, and the differences match those predicted by the theories of relativity.
Oddly enough, if gravity does manipulate time, black holes could possibly be wormholes between universes due to time being distorted to the point of… Something or other. The point is that time would move at an exponentially increasing rate, possibly reaching infinity times infinity or something crazy like that. (Now aren't we glad that the universe isn't a computer? It'd have crashed so many times trying to compute infinity if it was.)
Since time slows as gravity increases, this theory would predict that time stops at the singularity of a black hole, rather than speeds up.

Right. I was back-to-front then, I guess.

Well, that'd explain why the universe hasn't BSOD'd yet.

Having time stop would be a lot more boring than time going at speeds of infinity plus eighteen to the power of elvis, though.

If you insist on taking gravitational time dilation into account, people in space will actually age slightly faster because time is less distorted around them by gravity then it is for people on Earth. However, this difference would be on the scale of nanoseconds.
Alright, this is what I was thinking of. This is why I'm not going to be a physics major.

Black holes aren't "holes in time" or "holes in reality". As far as I know they aren't holes at all, black holes are just objects with such an intense mass that their gravitee can hold in light. Which is why they are black.

We never said they were… I was just saying (While thinking back-to-front) that if time sped up as gravity increased (Which is back-to-front) then at the point of singularity inside a black hole, time would be going F*cking Fast™, which could cause Strange Things™ to happen around that point, possibly including a wormhole effect. However, as that is back to front, in a black hole time would probably just stop or go Hella-Slow™.

OK, I did some reading, and apparently I wasn't too far off. According to special relativity, the faster you go, the slower you age. However, you have to be going VERY fast for this to be noticeable...you have to be somewhat close to the speed of light, which is 300000000 meters per second, which is obviously impossible by any means we have today. Something like that, anyway.

Means we have today?

What about THROWING SOMEONE INTO A BLACK HOLE!

They wouldn't survive but they'd live forever.

I think that your body would be long enough that gravity at the closer end would be much higher than gravity at the farther end, and this difference would tear you apart.

Seems I missed out on most of the conversation...

Oh well, not sure if this has anything to do with it, but my friend was telling me about a book he read where there were people living on the moon, and the lived slightly longer then people on earth (don't know why) and they didn't show signs of aging (wrinkles and such) as quickly because of the lower gravity. Was a fiction novel, so whatever. Not sure what I'm talking about anymore.

Interesting to see how my movie creating an argument in astrophysics though.
