Episode notes
Up and Down in Space
- In space, there's no universal up or down like on Earth.
- Objects in orbit fall together, maintaining relative position as seen on the International Space Station.
Inverse Square Law of Gravity
- Gravity's strength diminishes with the square of the distance from a massive object.
- This inverse square law explains why gravity weakens as you move further from its source.
Scale of the Universe
- While the universe is vast, the scale of smallness extends even further.
- The smallest structures might be much smaller than the known universe is large, according to Wolfram's physics project.
