Episode notes
Time's Relativity
- Time is more personal than previously thought, thanks to Einstein.
- It's relative to factors like speed and gravity, not a universal constant.
Satellite Clocks
- Clocks on satellites in geosynchronous orbit tick differently from Earth clocks.
- This is due to differences in gravity and relative speed.
Pan Am Experiment
- An experiment with atomic clocks on a Pan Am jet confirmed time dilation due to gravity.
- Time passed slower on the ground than for the clock on the plane, despite its speed.
