Centrifugal Gravity

Examples

• 1970 Ringworld

  The Ringworld spins very quickly to create gravity for its inhabitants, even though its shape cancels out any real gravity its mass produces (as all its inhabitants are on the inside surface of the ring).

• 2011 The Martian

  Hermes has a habitat ring that generates artificial gravity by spinning.

• 2021 Project Hail Mary

  The Hail Mary splits into two sections connected by cables, then spins end-over-end to create artificial gravity in a very small ship.
