Not all infinities are equal, from https://en.wikipedia.org/wiki/Cardinal_number https://en.wikipedia.org/wiki/Cardinal_number: "A fundamental theorem due to Georg Cantor shows that it is possible for infinite sets to have different cardinalities, and in particular the cardinality of the set of real numbers is greater than the cardinality of the set of natural numbers."
