Again, no. It is the unbalanced real contact force with the ground that causes the proper acceleration.Buckethead said:The point I was trying to make was that without spacetime curvature at the Earth, you would not feel a proper acceleration while standing on the Earth because you would not be forced to deviate from an inertial path through spacetime.
Any scenario in which there is an unbalanced real force will lead to the sensation of proper acceleration (with or without curvature). Any scenario in which there is no unbalanced real force will lead to the absence of proper acceleration (with or without curvature). The presence or absence of curvature is irrelevant.
Remember that spacetime curvature is tidal gravity, the sensation of proper acceleration is not. So what does spacetime curvature do in this scenario? It allows you to have proper acceleration in the opposite direction of a person on the other side of the world without the distance between you increasing.
This is getting annoying. No matter how many times you repeat it the answer will still be no.Buckethead said:That being said, doesn't it follow that if there is no curved spacetime at the surface of the Earth, one would not feel proper acceleration while standing on the surface of the Earth?
