How The Penrose Singularity Theorem Predicts The End of Space Time

Sep 19, 2026 · 21m

Summary

This episode explores Roger Penrose’s Nobel Prize-winning singularity theorem, which proves that black holes inevitably contain singularities where spacetime ends. The host explains how this discovery revealed the limits of general relativity and inspired Stephen Hawking to apply similar logic to the Big Bang, suggesting time itself began there. The discussion concludes with a Q&A on quantum mechanics, addressing the Many Worlds interpretation, relational quantum mechanics, and the relativity of the present moment.
