It may not be ill-timed to assert at this point the belief that all planetary bodies are hollow and cool, not one in a molten condition or giving out heat, but only generating heat in their own atmospheres, thus giving out light, which we, in our ignorance, attribute to a mass of intense heat or a globe in combustion. Such a condition seems unreasonable to exist in a body traveling unlimited space, which is cold beyond any degree of ascertaining. The sun is subject to the same conditions as the Earth, as far as obtaining heat, and this work will claim that we receive no more direct heat from the Sun than from Mars or Venus. Taking the first proposition, that in the absence of friction there can be no heat or light, the assumption is that the Sun generates its heat and light by its wonderful revolution in its own atmosphere. With a diameter of 860,000 miles, and revolving in 25.38 days, the Sun is moving through its atmosphere a mile in eight-tenths of a second, and seventy-five miles a minute, and 4,500 per hour. With an atmosphere of relative density of the Earth’s, it is easy to see what a pyrotechnical and electrical display this would reveal to the lens of a telescope, giving the impression of fire on an inconceivable magnitude. It seems unreasonable that in the realm of Nature anything, or that anywhere fuel can be found for an eternal fire except in an old orthodox Hell. To an observer on Mars or Venus, the earth would, no doubt, present the same starlike appearance that those planets do to our earthly eyes. The electrical sparks on a trolley wire or dynamo give the same expression to our eyes, though in miniature, with no consciousness of heat to our feelings. It is doubtful if, with all the observations of the Sun by telescopes, we have gained any knowledge of its structure, but only of its revolutions, size and movements, the same as the Earth. It would be a very difficult subject to diagnose clearly as to its productions of animal and vegetable life. The electrical influences through an atmosphere proportionally deep with ours, with its clouds that must exist in the same, could very thoroughly obscure the surface of the Sun. Unless at special intervals, when certain exposures would be called Sun-spots, either on a great space of continent or ocean. The great flames of gases in the atmosphere would give the impression, by telescopic view, of a burning mass, when under these atmospheric flames all is cool and calm.
