Episode notes
Did Black Holes Precede Galaxies?
- Some theories propose galaxies formed around pre-existing primordial black holes.
- Other theories have black holes growing after or alongside galaxies via accretion and mergers.
Why Deep-Sea Giants Evolved
- Deep-sea gigantism likely arises from colder temperatures, slower metabolism, low predation, and sporadic food pulses.
- Larger size helps store energy, improve metabolic efficiency, and cope with pressure and oxygen limits.
Giant Deep-Sea Isopod Example
- Bethynomus gigantus is an isopod that reaches 12–20 inches and can fast for years.
- It scavenges on the seafloor and survives long starvation with a very slow metabolism.
