Teorema de Cantor

Cantor's Theorem states that, for any set of elements, the collection of all its possible subsets (called its power set) is always larger than the set itself. For example, even a simple set like {a, b} has a power set of four subsets, including the empty set and the set itself. This concept reveals that there is no way to list all subsets without missing some, illustrating that there are different sizes of infinity. In essence, it shows that the "size" of a set’s collection of subsets always exceeds the original set's size.
