here's a simple experiment that casts doubt on gravity.

take 3 rooms, and 3 objects. a room with a vacuum, a room with 1 atmosphere of pressure at 14 PSI, and a room with several thousand atmopsheres of pressure at 200,000 PSI. the 3 objects are a ball, a ballon, and a feather.

in the vacuum, the ball, and the feather fall at the same rate, because there is no air resistance for the feather, and the balloon floats up.

in the 1 atmosphere room, the ball falls at the normal rate neglecting a little air resistance. the feather falls at a much loser rate because it is struggling to push away the air, and the balloon floats to the top of the room.

the 3rd room with 200,000 PSI of atmospheric pressure when you release the 3 objects none of them move. the ball and feather are not dense enough to push the air away so it can fall down. the balloon is not strong enough to push the air out of the way so it can float up

this can be observed in the ocean. when a whale dies 1 of 2 things will happen depending on how deep the whale is in the ocean at time of death. it will either float to the top, because the atmopshereic pressure is not strong enough to push the corpse down. or if it is deep enough, the atmospheric pressure is strong enough to push the corpse down at the bottom of the ocean.

this is why cannon balls can not sink in mercury. this is why wood floats on water. its a matter of density.

if gravity were a thing clouds would not be able to float, for they weight millions upon millions of pounds of water.
