There are different levels of infinity. That is for sure.

A simple way to get to infinity is the set of all numbers N+1. For any number I can name a number bigger by adding 1. This is a very small infinity. But its much bigger than all the stars in the universe.

An intermediate set is the set of all numbers derived by a set of functions where 1/N^K where k is all the numbers from 1..N.

Then there are the numbers from the set of ALL functions that are continous, which is also infinite.

In each above case, you can show that each set is infinitely larger than the other.

And it gets even more interesting than that.

It gives me vertigo when I think about it.
