Infinity's Size: Mathematicians Get Closer to Answering How Many Real Numbers Exist
2025-01-09
For decades, mathematicians believed determining the total number of real numbers was an unsolvable problem. A new proof suggests otherwise. The article details how mathematicians Asperó and Schindler proved that two axioms previously considered competing foundations for infinite mathematics actually imply each other. This finding strengthens the case against the continuum hypothesis and indicates an extra size of infinity exists between the two that, 143 years ago, were hypothesized to be the first and second infinitely large numbers. While this result has generated excitement and debate within the mathematical community, the arguments surrounding the sizes of infinite sets are far from settled.
