Can you confirm that Theory? No. Can you confirm mass, density, and buoyancy? Yes. The gravity Theory has many holes. Based off gravity Theory, objects with larger masses attract small mass objects. If this were true, then all kinds of random objects would just attract to each other no? Can a penny magically attract to say a large cargo ship, based off of gravity? No.

Gravity requires mass. It's clear you don't understand how gravity works.
