What is Aleph-null? Is it the set of all integers? or is it something a 
little different. I know it's basically a different sort of infinity...

[A Quick wiki detour later] Oh, Aleph-Null is basically any infinite 
set, Aleph-One would be a set of all ordinals (positive integers and 0) 
.. Interesting
