Episode notes
What A Black Hole-Within-Universe Would Look Like
- If our universe sits inside a black hole, observers inside would see incoming matter funneled toward the singularity.
- Merging parent black holes would appear as horizons coalescing and matter collapsing into one larger black hole.
Universe Selection Via Black Hole Fertility
- A proposed cosmic natural selection suggests universes producing many black holes are more likely to spawn descendant universes.
- We are likeliest to inhabit a universe whose physical laws favor black hole formation.
How Hawking Radiation Causes Evaporation
- Hawking radiation arises from particle-antiparticle pairs created by the gravitational field near a black hole.
- One particle can escape while its partner falls in, causing the black hole to lose mass over time.
