And BTW, the Earth is NOT ACCELERATING upwards. That is horsecrap.
Everyone knows Gravity is caused by Airpressure and Density in a closed-world system with a Firmament.
"Everyone knows" that the Air Pressure (actually, pressure in any gas or mixture) in any spot produces equal forces in every direction.
Well, obviously ALMOST "everyone".
And also everyone knows that as deeper you go, the "pumping" of pressure force is stronger.
Downward component is pressing from top of an object, upward component is pressing from bottom of an object.
Bottom force (upward pressing one) is deeper and it presses harder.
In the air both forces are small, but in water you can feel the difference.
(Or Water Pressure won't do the same thing, even water is heavier and presses harder?)
Ever been at beach?
And went into water?
And found rock in water?
And tried to lift it?
Next time bring manometer and measure pressure in water.
Also in deeper spots in water, if you can dive, or ask someone who can.
Compare it to pressure in Air.
Water is much heavier and difference between forces is bigger,
so, rock in water is lighter, much easier to lift, than when you bring it to the air.
There are pressure forces smaller, so is their difference, and "floating effect" of the rock
takes much smaller part in cancelation of the rocks weight.
But, in "your" theory, upward component of the pressure force in air is canceled
because you disliked it, Mr. Norris?
