Aleph Two

Aleph Two (ℵ₂) is a concept from set theory, a branch of mathematics studying collections of objects. It represents the size (cardinality) of the second "uncountable" infinite set, meaning it's larger than the set of all real numbers (ℵ₁). While ℵ₀ (aleph-null) describes countable infinity like natural numbers, ℵ₁ is the smallest uncountable infinity, and ℵ₂ is a larger uncountable infinity. In essence, Aleph Two is a way mathematicians categorize different sizes of infinite collections, showing that infinity comes in many sizes beyond the usual notion of endless counting.
