Zooming to the Bernal sphere, a scene with cocktail drinkers and a flying cyclist.

Guidice on the cyclist: “You could technically free yourself from gravity there, if you just stopped rotating—if you got off the ground. The rotation creates the gravity, but if you were to match the speed of the rotation, it would become zero. So you could float off and float around in there quite easily.”
