Episode notes
Gravity Comes From Mass
- Everything with mass has gravity and gravity stretches all the way into space.
- Earth and the Moon pull on each other, causing tides as they tug on oceans and each other.
Newton's Apple Moment
- Isaac Newton wondered whether the force pulling an apple also pulled the Moon after watching an apple fall.
- He realised gravity doesn't stop at the clouds and extends into space.
Orbit Is Continuous Falling
- Astronauts on the ISS still feel about 90% of Earth's gravity while orbiting.
- They float because they fall around Earth, moving sideways fast enough to keep missing the ground.
