many people do not know what "deja vu" means. but if anyone claims "deja vu does not exist" it makes one wonder. are they saying the phenomenon of remembering something that just happened again, isn't something that has ever been experienced by anyone else? or are they just not understanding what the word means. it's more than just semantics. one has to become clear on definitions before they can move past the understanding about it. if we think gravity does not have a force then that is a popular understanding. but to say that volume has a force, then we can test that thesis. we would be able to test that thesis by running the cavendish ( https://ytprivate.com/watch?v=Ym6nlwvQZnE&t=45s ) but with larger items with the same mass versus smaller items with the same mass versus largest items with higher mass. I expect the higher mass to win, irrespective of density. suppose item A is a perfect cube. It is 12" cubed. It's volume is 100 lbs per cubic foot suppose item B is a smaller perfect cube and has the same mass as cube A. It is 6" cubed. That means it's volume is 200 lbs per cubic foot suppose item C is a perfect cube. It is 12" cubed but has more mass. It's volume is 300 lbs per cubic foot. The gravity force theorist would expect the results to be same for A and B (because they have the same mass, in spite of their size difference), but more of a drastic state change to item C. The mass force theorist would expect the results to be item C most drastic, followed by item B, followed by item A, the weakest.
