Episode notes
Black Holes Demand Unified Physics
- Black holes uniquely require us to unify quantum theory and general relativity.
- They are natural sites that demand a deeper theory of space and time.
Time at Black Hole Horizon
- Time behaves differently at a black hole's event horizon depending on your viewpoint.
- An outside observer sees time stop, while an infalling astronaut experiences normal time flow.
Singularity as End of Time
- The singularity inside a black hole is not a place in space but a moment in time.
- It represents the end of time where physics as we know it fails.
