What I don't understand is that this "theory" seems really easy to disprove. Why do things travel down instead of up or right or left?

Lol, the author wishes to remain anonymous? Can you imagine knowing something so profound, and revolutionary, spending hours dreaming up formulas and discovering the real truth, then hiding your identity? This is a joke, right?
He writes> it is clearly the density of the object and the density of the medium it is in, nothing more
So what about a steel ship? Metal is dense, just like the steel bolt in his beaker image. If it were only about density, why do ships float?
This paper is 100% laughable.
Idiot. Ships float because it displaces their weight in water. What is an 'air pocket' anyway? lol.
The hull is what allows air to displace water.
If you filled that hull with any other substance heavier than water, it still displaces water, but it will sink.
If you fill that hull with anything less dense than water (vegetable oil, liquified gas, air) it will float.
Even with a very heavy lead hull this works. If the hull is too thick, where its total volume (including its contents of air/oil/whatever) is more dense than water, it will sink below the water's surface and the pressure difference between water and air can be corrected, the air escapes like a bubble would, back to equilibrium. But say you cap off the hull before it sinks...now it still might sink but as it is sinking, pressure of the water above it grows and will cause it to burst. However, if the air inside it was pressurized (like a submarine), then it might not burst. The increased air pressure gives the sub more density, as density increases proportionally with pressure.
The reason airplanes are pressurized is to mimic conditions at sea level for humans because its comfortable. You asked what an air pocket is, which is related to a low pressure zone of air in the atmosphere that an airplane passes through, causing it to dip in altitude. But you know the thing!
The Titanic sank.
Malaysian Flight 370 crashed.
A steel boat holds air, that's why it doesn't sink, the air that it holds is less dense than water, so it reaches an equilibrium with the weight of the boat and achieves buoyancy.
No, that is wrong. It has nothing to do with air because the ship is not air-tight. It does not sink because the hull tries to displace its weight in water. So take two hulls; both weigh 1 ton and contain the same amount of air. One is shaped with a flat bottom, very wide with low sides, the other is a very narrow wedge with super tall sides, which one would sink? The wedge would sink because it does not have enough sideways displacement force to counteract gravity.
So Bull Boat vs Canoe or what?
