In the summer of 1930, a 19-year-old student sailing from India to England passed the weeks at sea doing math and arrived having shown that massive dying stars can collapse entirely. This episode explores the life of Subrahmanyan Chandrasekhar, born in Lahore in 1910 to a mother who translated Ibsen into Tamil and a family that included Nobel laureate C.V. Raman, who won the physics prize the same year Chandra boarded that ship.

The hosts break down the physics of degenerate electron gas pressure and how factoring in special relativity revealed a hard limit of about 1.44 solar masses, beyond which nothing stops gravitational collapse. They recount the 1935 Royal Astronomical Society meeting where Arthur Eddington publicly shredded the theory, how Chandra sought counsel from Niels Bohr and Leon Rosenfeld rather than fight in the press, his move to the University of Chicago’s Yerkes Observatory in 1936 over a dean’s racially motivated objection, and his decade-long cycles of systematization across stellar dynamics, radiative transfer, hydrodynamic stability, and black hole theory.

• Why electrons pushing back against gravity hit a cap set by the speed of light while gravity has no cap
• How Chandra drove 300 miles round trip in Chicago winters to teach two students, Tsung-Dao Lee and Chen-Ning Yang, who both won Nobel Prizes
• Why, as editor of the Astrophysical Journal, he published Eugene Parker’s rejected 1957 solar wind paper after checking the math himself
• How his wife Lalitha Doraiswamy, a physicist in her own right, built the stable foundation for his monastic focus
• Why the 1983 Nobel Prize, shared with William A. Fowler, frustrated him by honoring only his earliest work
