My actual question is if gravity repels as well as pulls. I know, according to Newton's third law, that every action has an equal and opposite reaction. So can the force we label gravity actually be the result of the supposed empty space around it exerting pressure onto objects of mass? [This question has been plaguing me as of late due to my swimmers ear. I often lose balance when my inner ear goes off.] This question probably sounds dumb to some, but I am new here so I was wondering if anyone had a quick answer.
