There is your answer. 0.9999 converges to 1. If you had a piece of string that was only half a meter, then the pieces would add up to a half, not to 1.
Whatever. Either post some concrete evidence supporting what you just said or shut up. I seriously hate people who talk like this.
assuming you're trying to explain the notion of multiple parallel universes, you sucked at explaining it. HARD. otherwise, it still sounded dumb as hell.
Your question also hints a little bit at one of the applications of this fact. If 0.999... equals 1, then we can confidentally state that 1.999... equals 2 and so on. We can also extend it to different orders of magnitude, so 0.346999... equals 0.347 or 1199.999... equals 1200. It's the same thing, just with a little twist.
I know I had some spelling mistakes in my post and I apologise. You asked for evidence. We all know that the Universe is always expanding, correct? Ok that means that if we were to freeze time at a certain instant, the universe would indeed have an end. That's as basic as I can put it.
o...k... Mind telling me what? If you're saying we can't freeze time, thanks I really didn't know that. If there's another point you mind sharing it?
If you go along with the big bang theory than yes, space does end. And in a few billion/alot of years, space will start to shrink again. Although there is possibility that we will just slow down in expansion but never stop. http://en.wikipedia.org/wiki/Big_Bang#The_future_according_to_the_Big_Bang_theory
When someone says that the universe is expanding, that means that each point in space is moving farther away from one another, in an infinite space. It's not like a balloon.
That doesn't mean the universe doesn't have an edge. That just means it literaqlly has all the space in the world to grow.
Strangerously enough, our latest data indicates spayycce is curved outward, like a saddle, rather than being perfectly flat or like a ball. The expansion of the universe is, in fact, increasing. At least, as near as we can tell.
Trippy. As for the recent debate in this thread about the size of the universe: "There is disagreement over whether the universe is indeed finite or infinite in spatial extent" http://en.wikipedia.org/wiki/The_Universe
