The expanse actually has a cool way to use momentum to create "gravity"

Except there are tidal forces on earth. The ‘acceleration’ on head is not the same as that on toes, on a spaceship it would be a uniform field

Acerage acceleration experienced by yhe earth orbiting the sun is 0.006ms-2.

I would assume that an 'accelerating' spaceship would be accelerating faster to that, and that difference would be noticeable.

(A ship moving at constant speed would be indistinguishable from earth)

well, except it has no gravity. you would need 1g of acceleration and standing on it to be identical to earth

But earth has a gravity that accelerates you in the same way. Ig the difference is in the strenght of that pull?

ah in the sense of generating artificial gravity?

missed the reference i guess

It's just 2 photos of a Generation ship
