well, from what i collect, it's infinent.
then how's it expanding, you say?
well, take a balloon. now, imagine it blown up a bit.
mark two Xes on it.
now imagine you're a very small ant on the balloon. to you, there are only 2 dimensions to the balloon. the balloon is now being slowly blown up.
every day, you walk from one X, where you life, to the other X, where you work.
and every day it gets longer.
but yet, there are no edges.
yes, it does assume a 5th dimension (assuming time isn teh 4th)
i'm pretty sure time IS the 4th. i've never heard theories of a 5th dimension before. but then again, i haven't really researched theoretical science recently..
and you can NEVER hit the edge. at least, not in our lifetime with our technology. even if we do create something that can go at the speed of light, it would take YEARS to go to even the next galaxy. and it would need A LOT of energy. (no, we can't use coal, fuel, electrocity, solar power, ect.).
right now, i think everything's just basically theories. they say that for our universe to be expanding, there has to be another universe outside of it.
it's a scary thought just thinking of how big everything is. if we compare ourselves to the whole universe, we'd be a speck of dust! (no, much, much, much, much smaller than that.) if we were to make a scale model of our galexy, we'd be a fentometer (i think it's 10^ -15 or was it -12?)!
