According to Einstein something massive, even of small mass, creates a sort of "distortion" in spacetime that pulls objects towards it. As an example let's just assume globe Earth is real for now and think of how that would work. You would get pulled around to the center of mass of the object due to the mass on all sides on globe Earth having the most pull toward that direction. Still thinking about globe Earth, if you went in a spaceship; as you get farther away in space from globe Earth, the gravitational pull would weaken on a curve until it is barely noticable. Now think about that on flat Earth. The center of gravity would be in the center of the whole plane known as Earth, meaning as you walk further away from the center it would be like walking on a slope. But we don't get that effect. Can anyone explain why? Is Einstein's theory of general relativity not credible? Because as far as I know it has been proven on things on this Earth! Meaning at least some of it applies. I can't grasp this...
