Most egregious Flat Earth claim - Gravity is simply buoyancy & density - Debunked
First of all, buoyancy depends on gravity. If there is no gravity, there can be no such phenomenon as buoyancy. Look up the definition of buoyancy on Wikipedia or search buoyancy NASA on google, if you don’t believe it. If gravity is simply buoyancy and density then why does hot air rise and not go down instead, or sideways? I’ll tell you why. Because we live in an environment where there is a downward force acting on things based on their mass. This can be experimentally verified and it does not depend on assuming the earth is a sphere. If I put 5 apples in a grocery scale I will get a certain weight (force). If I put an additional 5 apples of about the same size in the scale, the scale will register about twice the weight. So the force known as buoyancy depends on this downward force proportional to mass. This is why the deeper you go in a body of water the more pressure there is. This is why the higher you go in the ...
