Episode notes
Telescope Origins
- The telescope wasn't invented by Galileo, but by Hans Lipperhey in the Netherlands.
- Galileo improved the telescope's magnification by 10x, transforming our view of the universe.
Telescope as Time Machine
- The telescope allows us to look back in time, seeing distant objects as they were millions of years ago.
- This "time machine" aspect of telescopes unlocks unique insights into the universe's past.
Early Universe
- The universe began as a fusion reactor, creating lighter elements like hydrogen in the first few minutes.
- Heavier elements like iron and carbon formed later through supernovae, another type of explosion.
