Quote:- “The solar atmosphere is actually a vacuum by most standards”

So in terms of current theory, as the atmosphere is composed of vacuous atoms in eternal kinetic motion in an extra-atomic vacuum.
But in this case there is absolutely no possibility of the transmission of a force, e.g. between the material structures of the Earth and the Moon, or with that of the Sun.
However it is rather obvious that there are forces acting to maintain the orbital motions of both bodies.
So there are two options, either continue believing in this impossibility, or accept that there is a fundamental fault with this theoretical base.
Facts:-
It is stated that one cubic centimetre of atmosphere at the Earth’s surface is composed of (a practically inconceivable number) 25 x 1018atoms.
It is observed that a ray of light entering the Earth’s atmosphere is refracted and coincidentally that its velocity is fractionally reduced.
This can only be due to interactions with the progressively increasing densities of the gases of the atmosphere, in other words with the component matter of the atmosphere, the atoms.
But all physicists apparently believe that the force that you call “gravity” can act through an absolute vacuum, or through hypothetical “vacuum filling” aethers .
In the first diagram below the atoms depicted between the Earth and the Moon are each representative of innumerable numbers of atoms in reality.
And in accordance with the observed collective densities of atoms with altitude from the Earth’s surface these atoms increase in volume and decrease in mass density, as is indicated by the rapid evaporation of liquid mercury observed in these experiments. And it is stated that the rate of its evaporation doubles with an 18oC rise in temperature.
And, it can only be concluded, that mercury atoms individually expand in volume and that their individual mass densities are lower than that of the combined atmospheric gases.
The mass densities of the atmosphere patently decreases with increase in altitude.
The second images depict atoms that increase in mass density exponentially to the core.
So there are just two options for the transmission of forces universally:-
1) Vacuous atoms in vacuum.
2) Vacuum is a universally impossible state. Instead there is a universal continuity of wholly material atoms which are continuous and expand (and contract) with input (emission) of energy and fractionally decrease (increase) in mass density and accordingly increase (decrease) in fluidity.
