Are you a hollow Earth guy?
No. But I do have science degrees in other fields. I've been asked a couple of times by geology professors (I like to sit in on geology classes.) to write a paper about this when I've discussed it with them, but I really don't know much about writing such papers and haven't done so,

If you had a hollow earth, would gravity pull you towards the center of the sphere? Yes. I believe gravity would be highest at the center, so anything other than a singularity would feel tremendous gravitational pressure at the center.
So the question is would that pressure be any different in a non hollow earth? I don’t think so. Or maybe I am wrong? Would the center be an “anti” gravity peak effectively repulsive? Are objects attracted to the center of mass even if the center of mass is not in the mass?
