Some may object to the Theory of the Lines of Gravitation being the only "carriers" of the Energy of the Sun, as being contrary to the conception of Science that the Sun radiates Energy _in all directions equally_, just as does a piece of hot iron, or a lamp. Answering this objection, the writer would say that there is a decided difference in the two cases. The iron or lamp radiates its heat and light to the particles of the surrounding air and other Substance in close distance, the "lines" being very close together,--so close in fact that they seem to be continuous and having no space between them, at least no Space sufficiently large to be detected by the eye of Man, or his instruments. But with the Sun the case is different, for the distances are greater and the lines spread apart as the distance is increased. Draw a diagram of many fine rays emanating from a central point, and you will have the idea at once. If Space were filled with Substance, just as is the Atmosphere of the Earth--the Air, is meant of course--then indeed would the lines practically be joined together, but as Space between the worlds is almost devoid of Substance, the lines between the Sun and the other worlds, and planets, spread out rapidly as the distance from the Sun increases. To show how this objection is really an additional proof of the Theory the writer begs to call your attention to the fact that according to the calculations of the physicists in Science, the Sun's energy would have been exhausted in 20,000,000 years, granting that it was dispersed equally in all directions during that time. But, _note this_, Science in its other branches, namely in Geology, etc., holds that the Sun already has been throwing out energy for 500,000,000 or more years, and seems able to stand the strain for many millions of years more. Thus Science is arrayed against Science. Does not this Theory harmonize the two, by showing that the Sun does _not_ emanate Energy in _all_ directions, equally, and at all times--but, on the contrary radiates Energy _only along the lines of Gravitation, and in proportion to the relative distances and sizes of the bodies to whom such Energy is radiated_?
