comment What would happen to a rocket car in a torus-shaped spaceship that encompasses the earth?
Well, think about how a rocket works. It chucks some mass out the back to propel itself forward. Momentum is conserved, so the total momentum carried away by all the exhaust is exactly equal in magnitude but opposite in direction to the momentum of the rocket. If the exhaust stays in the station, this momentum will be dissipated into the station (exhaust particles colliding with the walls), and will exactly compensate any momentum imparted to the station by the rocket -> nothing will happen.

Top 10 based on what criteria? This is totally subjective, and thus off-topic.

comment What would happen to a rocket car in a torus-shaped spaceship that encompasses the earth?
Well, the total angular momentum is going to be central here. I'd say a vital question is "what are you doing with the exhaust of the rocket?"...
