He called rivals "spherical bastards," bastards no matter which angle you viewed them from. This episode unpacks Fritz Zwicky, the abrasive Caltech astronomer who rewrote our understanding of the universe while alienating nearly everyone around him.

We trace how a physicist trained in crystal science came to see the cosmos through structural math, predicting dark matter, supernovae, and neutron stars decades ahead of his peers, even as his stubbornness produced spectacular misfires.

• Using the virial theorem to infer unseen mass in the Coma cluster
• Coining "supernovae" and predicting neutron stars with Walter Baade
• His self-devised morphological analysis for lateral thinking
• Wrong turns like "tired light" and "nuclear goblins"
• His postwar humanitarian book drives and rocket work
