I know that rotation can cause there to be artificial gravity. But I was thinking of making a floor plan that is all horizontal with the generation ship having a rocket shape and with it being longer than it is wide and wider than it is tall. So I was thinking of giant centrifuges on every floor. The centrifuge underneath the floor would cause there to be a downward gravity and no worries about the Coriolis effect. At least I think it would. And I think that there is a way you can configure all the centrifuges so that the gravity everywhere is 1g. So how fast would each centrifuge have to rotate in order to have 1g gravity downward throughout the ship? The problem I see with rotation of the entire ship is not the Coriolis effect per se but rather dizziness and nausea, especially if a person already has dizziness or nausea. Basically, rotation of entire ship = gravity + motion sickness + dizziness(fluid in ears rotates in response to the ship rotating and thus the brain gets confused). Plus, potential collisions would be way worse due to the rotation. With the centrifuges I do believe that the floor in the middle would need to have its centrifuge rotating the fastest and the ones on the top and bottom have their centrifuges rotating the slowest for 1g gravity. Whatever the answer is, I know that there have to be different rotation rates for gravity to be even. Note: I am using newtonian gravity here, in other words a true force. General relativity would just make things way more complicated than it has to be.
