Now you're trying to confuse me with technical stuff, that's "candy from a baby"...too easy to be any fun. However, learning trumps point scoring in the serious threads, in my book, so here goes.

Would I not be right to say that an asymptote is just a mathematical device which bears no more relevance to the real world than did Zeno's paradox. An asymptotic relationship involving deceleration breaks down at Planck's length and Planck's time, if not before. Mathematical infinity, yes; physical infinity, no.

There never was nothing.
