Some infinities are larger than others. Consider the set of all numbers between 0 and 1 - there are an infinite number of them. (0.1, 0.01, etc.) The set of all numbers between 0 and 2 (or, for that matter, 0 and 1.1) is also infinite, but it's a larger set than the set of numbers between 0 and 1. It is in fact possible for something that is infinite to become larger, while still being infinite. -Dan /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
