That is infinity for you. This means we cannot get more than infinity by raising infinity to any non-infinite power. Here is where it starts getting deep, folks. A little over a century ago, a mathematician named George Cantor discovered that there is more than one kind of infinity. He proved that there are infinitely more real numbers than there are integers.
All rational numbers are reals, of course.
As demonstrated above, we can count the number of rational numbers. Cantor proved that this is not true of reals. What we have done is create a new real number that cannot be on the list, because it has to be at least one number off from every number on the list. Thus, there are infinitely more real numbers than there are rational numbers, or integers. This leads to the conclusion that some infinities are more infinite than others.
