Why is it that when something pushes/pulls on me, I feel acceleration, but I don’t feel acceleration from the earth’s gravity? I feel a force pushing upward on me, but I don’t feel a downward force.
In: Physics
In general relativity the explanation is simple but weird: earth’s crust is moving upwards at the same speed earth is stretching space downward due to its gravity.
So the only force we receive is the one from the floor, accelerating us upwards against the free fall, which would be the normal flow of space-time.
