Episode notes
Mutual Attraction Of All Masses
- Gravity causes any two masses to attract each other, so even people and pens exert mutual pull.
- The pen and the Earth move toward each other, but the pen moves far more due to different accelerations.
Baseballs And Pens Still Pull Each Other
- Hannah Fry recounts calculating two baseballs a metre apart would collide in three days from mutual gravity.
- She also describes how a dropped pen pulls the Earth an almost immeasurable distance upward.
Limits Of Newtonian Gravity
- Newton described gravity as a force causing objects to accelerate toward each other via F=ma.
- But his model implied instantaneous action, which conflicted with later observations and relativity.
