How To Capture Black Holes

Oct 26, 2026 · 18m

Summary

This episode explores a hypothesis that massive black hole mergers occur within the accretion disks of supermassive black holes, a process that could explain unexpectedly heavy merger masses. The hosts discuss two 2019 papers predicting that gas in these disks accelerates merger rates and generates detectable ultraviolet flashes following gravitational wave events. The segment concludes with viewer comments addressing Lee Smolin’s cosmological natural selection theory, specifically how inflation allows new universes to form from limited matter.
