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 ...

What's the gravity maintained in Ceres?

As far as I remember, they never gave out that level of detail on the TV show. We're just told that Ceres has much lower gravity than Earth. In the novels that the show is based on, the gravity is ...

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 ...

Why is the crew of spaceships exposed to quakes and trembles in a battle?

Whatever means of generating artificial gravity you have, it can't react to changing acceleration quickly. If it could react quickly, it could conceivably start oscillating (gravity going up and down ...
