Mathematicians, on the other hand, tried to demonstrate that their
alternate worlds couldn't exist - and found the math in their failures
interesting. Hence we get non-euclidean geometries and other
interesting things - that physicists find useful. (To be fair, some
of the alternate mathematical world were first explored by physicists).
