When I was young, I had boats floating in my bathtub. Yes, it is the same but only seamen swim ... If you are adept of Reinforcement Learning, as you seem to be, try this

The boat displaces the water. The displaced water pushing back and exerting pressure toward the boat keeps the boat afloat. The Earth displaces the supersolid dark matter. The supersolid dark matter displaced by the Earth pushing back and exerting pressure toward the Earth is gravity. The state of displacement of the supersolid dark matter is gravity.

For a serious, graduate level contribution to PO, your links should point to scholarly articles, not to material intended for laymen.
