You experience more Gs because you body is trying to go in hte direction the roller coaster was going before it turned or did the loop or whatnot. Its a pseudo force.
Why does paper fold under my pressure of moving it upward when i don't from this planet thing? Atmosphere isn't constant i thought if gravity didn't exist, unless I am wrong. Wouldn't the planet just move through the gas anyways without gravity? It still could make sense for gravity to exist but have dark energy prevent it from collapsing on itself.
I saw the thread about atmosphere just now, but it has more holes in it than 10 blowup fun dolls. A universal accelerator would work in one direction only, it can't have a counter force to specifically keep a atmosphere on our special plain thing, it would cause our FE to stop moving.
