Cantor's Theorem reveals that infinities vary in size, with the power set of any given set having a greater cardinality than the set itself. This theorem, established by Georg Cantor, is pivotal in set theory, illustrating the existence of an infinity hierarchy. Cantor's diagonal argument further demonstrates the uniqueness of infinite cardinalities, challenging our comprehension of the infinite and influencing various scientific fields.

Cardinality is a measure of the size of a set, which can be either finite or infinite
Definition of Power Sets
Power sets are sets that contain all possible subsets of a given set, including the empty set and the set itself
Relationship between Power Sets and Cardinality
Cantor's Theorem states that the power set of a set has a greater cardinality than the set itself, even for infinite sets
The diagonal argument, devised by Cantor, is a proof that demonstrates the non-equivalence of infinite cardinalities by constructing a new element that cannot be accounted for in a bijection between a set and its power set

Cantor's Theorem helps to quantify genetic combination possibilities in biology
Analogies such as all possible books and their summaries or finite and infinite binary sequences can aid in visualizing the concept of varying sizes of infinity introduced by Cantor's Theorem
