This being so, we have now to apply some of the facts taught us by electricity, and especially by the electro-magnetic theory of light, to our solar system, with the hope that we shall find further evidence of a Centrifugal Force which is physical in character, and whose action can be traced throughout the whole realm of space. Let us, in starting to apply some of the truths already learned, recall some of the facts concerning light, its production and its propagation. We recall the fact that light is produced by the action of the sun upon the Aether, giving rise to waves which speed away from the generating source with a velocity of 186,000 miles per second. We further remember that Hertz has definitely proved that these light waves are identical with electro-magnetic waves, as they ought to be if the Aether possesses an electrical basis, as Dr. Larmor and Professor Lodge suggest. In order that there may be no mistake on this point, let me quote from one of Hertz' papers, where, in his conclusion, he says: "The experiments described appear to me, at any rate, eminently adapted to remove any doubt of the identity of light, radiant heat, and electro-magnetic wave motion." Now, what I want to point out regarding this fact is this. If the sun gives rise to the aetherial light waves, and these light waves are identical with electro-magnetic waves as proved by Hertz, then the sun must either be an electrified body or else a magnet. It must be one or the other, because, if it were not, we should then have an anomaly in Nature of a body emitting electro-magnetic waves which is itself neither electrified nor a magnet. Therefore, according to our second Rule of Philosophy, such a body would be incapable of giving rise to these waves, as such a result would be contrary to universal experience and experiment. We know that the earth is a magnet, but up to the present it has never been proved that the sun is a magnet, although, as I shall show later on, Lord Kelvin and others have suggested such a possibility. If we assume that the sun is a magnet, our grounds for assumption would not be so strong at this point, and our reasons so philosophical, as they are if we assume that the sun is an electrified body. We have philosophical reasoning to prove that the sun is an electrified body in the fact that it emits or gives rise to electro-magnetic waves in the Aether, and no other hypothesis can be made other than that the sun is an electrified body, in order to prove the connection between the two. Thus we affirm that the sun is an electrified body, which like any other electrified body is capable of generating electric waves, and speeding them through the Aether with similar velocity to that of light. Not only so, but, like any other electrified body, it must have its electric field and possess the ability to electrify any other body by induction, that may happen to be in its electric field, as we shall see later on.
