Definition of infinity? Well, first of all, there are many infinities.

http://math.stackexchange.com/questions/5378/types-of-infinity

My personal semi-definition of infinity: infinity is one of those things
that, if you're trying to do arithmetic with, you're doing it wrong.

for all numbers, x + 1 > x.

inf + 1 = inf

ergo inf is not a number and you're doing it wrong
