The Physics of a Spinning Spacecraft in *The Expanse*
The Expanse should just change their post credits for each episode to include a list of homework questions. Seriously--there are so many great things to explore in this hard science fiction show. In a recent episode, one of the large spaceships (the Navoo) rotates in order to create artificial gravity (that's not really a spoiler). Let me get right to it. You are probably somewhere near the surface of the Earth and there is a gravitational force between you and the Earth pulling you down.
