Buoyancy and density

Chemists understand density. They understand why a tree floats on water. They use density in their equations. Specific gravity is the relationship between objects of differing densities. Then again it should be called specific density. They can even evaluate differing densities at changing temperatures or pressures.

Physicists do not understand this. It seems to me that physicists missed chemistry class in school. It is obvious from their equations. Every equation I have evaluated shows the physicist ignorance on this topic. F=ma, E=mc^2... Mass does not exist in the natural world. Mass is a zero dimensional measurement. To a physicist, an object falls because of this magical field called gravity. Gravity has never been proven and has never been observed. Gravity is the only concept/contruct that the Standard Model cannot produce.

The physicists' equations do not integrate temperature, pressure, electric or magnetic fields in their solutions. Yet those variables are all necessary to evaluate changes in position. Each variable is associated with a boson; Photon - Temperature, Gluon - Density, W+/- Boson - Magnetism, Z Boson - Electricity.

Why should a physicist care about density? First the planets are ordered by density. The planets closer to the sun are solids, next are the gas giants, then the ice planets.
• Mercury - 5.427 g/cm³
• Venus - 5.204 g/cm³
• Earth - 5.515 g/cm³
• Mars - 3.934 g/cm³
• Jupiter - 1.326 g/cm³
• Saturn - 0.687 g/cm³
• Uranus - 1.27 g/cm³
• Neptune - 1.638 g/cm³
• Pluto - 2.03 ± 0.06 g/cm³

Motion can only be determined by evaluating the Bosons involved. This series of pictures shows what happens to a floating piece of wood when photons excite the water below.
