The Supernova At The End of Time
Summary
This episode explores a new astrophysical prediction that the universe will end with "black dwarf supernovae" rather than just black hole evaporation. It traces the history of stellar evolution, from Subrahmanyan Chandrasekhar’s 1930 discovery of the mass limit for white dwarfs to the formation of iron stars in the far future. The host explains how new calculations by Matt Kaplan reveal that electron depletion during nuclear fusion lowers the Chandrasekhar limit, causing massive iron stars to collapse into supernovae. The episode concludes by addressing viewer questions on the arrow of time…
