now youve set kracus off with all his "knowledge" which isnt backed up by any thought whatsoever
oh and about the 3+ dimension. apart from saying the 4th dimension is considered 'time' (length, width, depth, duration), much of astronomy revolves about both the number "i" and a whole lot of extra dimensions - the 7th dimension is not uncommon
[edit] oops

Oh really? I hope you've got a good explanation for that.

to everyone who's saying "being at the edge of the universe and being in two places at once is wierd and impossible!" don't think about it like that, because you can only ever be in one place at once (barring obscure photon observation theories):
In most versions of top-down computer games will have you in the centre of the screen while the universe keeps moving. in this game universe, if one edge of the universe looped around, you wouldn't notice -- you'd simply keep walking and cross the 'border'. there is no 'border' to the universe -- it's all just moving around you (since you're the one observing it)

Yes. Because the universe is modelled after video games.

no, because the people i am explaining this to have most likely played video games, and the example i used models the theory extremely well.

Maybe I should have read the article before posting.

As opposed to what? Gravity's effects are not instantaneous, what explanation are you looking for?
Kracus gave you a link that states just that.

Whoa, that's news to me. Everything I'd learned to this point had always shown that it was indeed instantaneous.
Nifty.

Couldn't be instantaneous because of the whole faster-than-light deal and everything.

Right, I understand that. I was under the impression that gravitons were considered massless.
Gravity is something that I've only studied briefly, and certainly haven't been keeping abreast of developments like the one Krasuc posted.

Wrong. Light has a finite speed, gravity is instantaneous action at a distance.
I thought gravity had a speed?
edit: or maybe that was just a theory I was reading about
edit edit: upon further thought, I think I remember hearing that it's so monumentally fast (the propogation of gravity) that it's not worth bothering to try to measure, since it doesn't hurt calculations to assume it's instantaneous
edit edit edit: just saw Kracus' link, I'll be damned...
