10 Things You Didn't Know About The Expanse
6. The Thrust
One of the most iconic and instantly recognisable elements of The Expanse are its ships.
With few exceptions, the vessels we see in the show are all designed to use thrust gravity, using the force produced by their engines to pull the crew "down" and simulate gravity whilst in flight.
This is why each vessel, particularly those made with combat in mind, are built like office blocks; vertical, with ladders or lifts running between decks, and the floor always pointed towards the primary engines. This is also why brake-burns occur, ships flipping around to face away from their destinations when close, as the force imparted by the deceleration of the engines allows gravity to be maintained.
Each vessel, from the Rocinante to the giant MCRN Donnager, are build around this principle which, unlike the spin gravity we see on the OPAS Behemoth, allows for high-G burns and combat maneuvres without danger of stress to the ship's structure.
