10 Things You Didn't Know About The Expanse
5. Life In Space
One place where we see the advantages of spin gravity are on stations like Ceres and Eros, where the primary form of gravity is supplied by the rotation of the asteroids themselves.
This spin was achieved by Tycho Manufacturing some decades before the events of the show, the same organisation responsible for Tycho Station and the OPAS Behemoth.
The company used immense engines to spin the asteroids to the desired velocity, simulating nearly 1G of force to the upper levels. Due to the Coriolis effect however, as one descends "lower" into the station the force decreases.
This is where the worst of the slums on Eros and Ceres are, and well as where the most notable belter evolutionary mutations can be found, such as elongated limbs, weakened bone and muscle structure, and organ failure in high-G.
