Aether and Gravitation

by William George Hooper

I can give no other answer, and can see no other possible physical explanation than the one already given, which is, that they are bound to the sun by the two co-equal forces, the centrifugal and centripetal forces, and while so bound are carried round the sun by the electro-magnetic aetherial currents which extend out into space. It has to be remembered that the aetherial electro-magnetic currents circulating round the earth are situated within the aetherial currents which circulate round the sun, therefore the plane of the moon's orbit will coincide more or less with the plane of the earth's orbit. We have now only to go one step further to get our complete conception of the plane of the ecliptic.

In [Arts. 107] and [108] we learned that the sun was subject to Kepler's 1st and 2nd laws, and as a natural result we came to the conclusion that it, too, was circled round some central body. We have only to apply a similar course of reasoning to the sun and its central body as we have to the moon and the earth, and the earth and the sun, and then we arrive at our physical conception of the plane of the ecliptic, which is due to the aetherial currents that circle round the sun, while that body is carried round some other central body.

Thus by the circulating Aether currents, originated and outflowing from their respective sources, each source being immutably fixed and bound to each other by the two equal and complementary forces, can be accounted for, the uniformity of position and plane of the various orbits of the various satellites, planets, and the sun, as they move in one great plane, termed the Plane of the Ecliptic.

It could not be otherwise than it is, and thus another celestial phenomenon can be accounted for on a real tangible basis by accepting the existence of those aetherial currents which form the physical basis of all the celestial mechanism.

If further evidence were required of the existence of these rotating Aether currents round the sun, such evidence is found in that phenomenon of the solar system known as the Zodiacal Light, of which up to the present no physical explanation has been forthcoming. In the conception of the atomic and gravitating Aether which rotates round the sun, I venture to premise will be found the physical solution of this phenomenon also.

I will refer the reader to an extract taken out of Outlines of Astronomy, by Herschel (Art. 894), so that we may see what his conception of the zodiacal light was, and we will see how far his explanation is in conformity with our hypothesis of an atomic, gravitating and rotatory Aether medium.

He writes: “We shall conclude this chapter by the mention of two phenomena, which to me indicate the existence of some slight degree of nebulosity about the sun itself, and even to place it in the list of nebulous stars. The first is that called the Zodiacal Light, which may be seen any very clear evening soon after sunset, about the months of March, April and May, as a cone or lenticularly-shaped light extending from the horizon obliquely upwards, and following generally the course of the ecliptic, or rather that of the sun's equator. The apparent angular distance of its vertex from the sun varies, according to circumstances, from 40° to 90°, and the breadth of its base perpendicular to its axis from 8° to 30°. It is extremely faint and ill-defined, at least in this climate, though better seen in tropical regions, but cannot be mistaken for any atmospheric meteor or aurora borealis. It is manifestly in the nature of a lenticularly-formed envelope surrounding the sun, and extending beyond the orbits of Mercury and Venus, and nearly, perhaps quite, attaining that of the earth, since its vertex has been seen fully 90° from the sun's place in a great circle. It may be conjectured to be no other than the denser part of that medium which we have some reason to believe resists the motions of comets; loaded perhaps with the actual materials of the tails of millions of those bodies of which they have been stripped in their successive perihelion passage. If its particles have inertia, they must necessarily stand with respect to the sun in the relation of separate and independent minute planets, each having its own orbit, plane of motion, and periodic time.”

Let me call the reader's special attention to one or two statements of Herschel's given in this extract, in order to see how these statements harmonize with the view of the Aether submitted in this work. In the first place he states its shape is that of a lenticularly-formed envelope surrounding the sun, and extending beyond the orbits of Mercury and Venus, and probably to our earth. This harmonizes with the shape of the aetherial envelope as given in [Art. 70]. Then Herschel states it may be the denser part of that medium which we have reason to believe resists the motions of comets. That is exactly what it is, though Herschel failed to show why it should be the denser part of the Aether, as we have seen is the case, on account of its being gravitative. I will also prove later on, that Herschel was right with regard to the resistance of the motion of comets through it. Then he refers to its particles probably possessing inertia, as though he had anticipated the atomicity of the Aether, and assuming that atomicity, he was compelled to postulate inertia also as we have done in [Art. 48].

Lastly, he points out that each separate particle must have its own plane of motion, its own orbit, and its periodic time. Now this view fully coincides with that laid down in this article, where we have learned that the rotating Aether has its own plane of motion, that plane being the Plane of the Ecliptic, and as every particle or atom has its allotted place in the rotating Aether, then, as Herschel points out, the particle must have its own orbit, and plane of motion, and also its own periodic time. If, therefore, we had desired fuller confirmation of this atomic gravitating Aether, we could not have wished for more conclusive proof than that given by one of the greatest philosophical astronomers of the last century. We shall see later that Herschel also had a clearer view of cometary phenomena, and of the forces which played a part in those phenomena, than any of his contemporaries, when we deal with the origin and motions of all comets. Thus from Herschel we learn that the zodiacal light is caused by the atomic, gravitating, and rotatory Aether as that aetherial medium revolves round the sun, while at the same time every atom of the medium is itself in a state of rotation on its axis, as it performs its journey in its own orbit and in its own plane of motion.

Art. 110. Centripetal Force.--We have now to consider what is the physical cause of that part of the compound Law of Gravitation known as the Centripetal Force. As we have already learned ([Art. 10]), this force is really none other than the Attractive Force of Gravitation, in that its mode of operation always acts towards the centre of the attracting body, and hence was called by Newton the Centripetal Force.
