Mathematical Universes Hypothesis

The Mathematical Universes Hypothesis proposes that every mathematically possible structure physically exists as a parallel universe. Proposed by physicist Max Tegmark, this radical theory suggests reality is fundamentally mathematical in nature, with our universe being just one of countless mathematical structures that manifest physically. It eliminates the distinction between mathematical description and physical reality, implying all possible variations of physical laws and constants exist somewhere in the "multiverse." This hypothesis bridges abstract mathematics and concrete existence, offering a provocative solution to cosmology's fine-tuning problem while challenging our very understanding of reality's fabric.
