Episode notes
Olbers Paradox And The Night Sky
- If the universe were infinite and eternal, every line of sight would end on a star and the night sky would be as bright as the Sun's surface.
- Olbers used this logic to show the universe must have a boundary in time or space.
The Theater Vertigo That Feels Like Infinity
- Jonathan describes a childhood concert panic where looking up at a domed ceiling triggered a falling-through-space terror.
- He links that vertigo to moments of confronting ideas too big for his everyday understanding.
Two Competing Cosmologies
- By mid-20th century cosmology offered both steady-state and expanding-universe models, the latter implying a beginning in time.
- The expanding-universe idea led to the notion of a hot, dense origin later called the Big Bang.
