Is there any explanation as to why small scale vehicles—such as X-Wings and T.I.E. fighters—in “Star Wars” have gravity?

Because if such ships did not have artificial gravity or inertial compensators, the occupant would be reduced to chunky salsa every time the ship sped up, slowed down, or rounded a curve. This ...

Is there any explanation as to why small scale vehicles—such as X-Wings and T.I.E. fighters—in “Star Wars” have gravity?

For manned craft that travel at the speeds involved in Star Wars, artificial gravity is a necessity. Small changes in direction would produce forces that would pulverize a human pilot. So if you want ...

From the source novel, Leviathan Wakes, we learn that people live inside Eros. The spin does indeed threaten to spin them off into space, but the floor (really the exterior walls) prevent this from ...
