Stephen Crothers is a mathematician, physicist, and scholar of relativity who believes there are fundamental mistakes in the mathematics that have created an impenetrable confusion at the heart of physics for more than a hundred years. We talk to him about how errors in equations get propagated from mind to paper to pen, the ways in which relativity has created impossible features that defy explanation, and the curve-fitting crisis at LIGO and WMAP that undermines the foundational pillars of the Big Bang.
