What If Black Holes FUEL Dark Energy?
Summary
This episode examines a controversial theory by University of Hawaii astrophysicists Duncan Farrah and Kevin Croker, who propose that black holes are composed of dark energy and grow in mass as the universe expands. The hosts trace this idea back to Erast Glazer’s 1966 work on vacuum energy, explaining how "geodes" might replace singularities and drive cosmic acceleration. While the team claims supermassive black holes have grown too rapidly for standard accretion models, the episode critically analyzes the speculative nature of cosmological coupling and questions the statistical robustness…
