It is just too much for the writer to swallow. The heat of the sun is probably generated by bombardment of its outer atmosphere by cosmic rays consisting of subatomic particles drawn in by the gravitational force of the sun. We have a similar heated layer in the upper atmosphere of our earth where cosmic ray intensity is much greater and the temperature is hundreds of degrees higher than at the surface of the earth. Since the gravitational force at the surface of the sun is thirty times that at the surface of the earth, it is not difficult on this basis to account for the 6000 degree temperature at the surface of the sun, without making any fantastic assumptions of interior temperatures of millions of degrees. A hot outer atmosphere would not necessarily heat up the interior of the sun, as has often been argued.
Heat can travel only by radiation, conduction, or convection.
Radiation is stopped immediately by even the thinnest layers of opaque material, and conduction through thousands of miles of poorly conducting material is a very slow process. Some of the water on the surface of the sun will undoubtedly be evaporated by the intense heat, and may even become dissociated into oxygen and hydrogen, but the reverse of these processes will also occur, until a condition of equilibrium has been established. The ultimate result will be a gigantic turbulence on the surface of the sun, such as can be observed any time, but which will leave the interior of the sun unaffected. The cosmic rays which are drawn in by gravitational force consist mainly of subatomic particles such as protons, electrons and neutrons. If these are clusters of vortex rings which were produced in the interstellar ether by the turbulence of light and heat waves, then we have here a cyclic process which could go on indefinitely.
