Episode notes
Big Bang vs Black Hole
- The Big Bang was an outward push, not a collapse forming a black hole.
- Gravity pulls things inward, but the Big Bang caused space itself to expand outward rapidly.
Space as a Network
- Space is not just a continuum but made of atoms of space in a giant network.
- These atoms have purely relational properties forming the structure of particles and black holes.
Expansion of Universe Explained
- The universe expands because it started with a parameter indicating expansion rate.
- Objects held by forces (e.g., atoms) don't expand; only large-scale distances between galaxies do.
