With the conception of an atomic and gravitating Aether, the Nebular Hypothesis, therefore, for the first time is placed upon a sound and philosophical basis, because the condensation of Aether, which is matter and possesses mass, admits of the origin of other matter from it which also possesses mass, together with other properties, as elasticity, density, compressibility and inertia. When there is added to the atomic Aether the conception of a rotatory aetherial atom, as was indicated in Art. 44, we have at once a source from whence the rotation of the whole mass may be derived. Thus, as the condensation continued, and the nucleus or central part of the body was gradually formed, the rotation would be accelerated, because of the inherent energy which would exist in the condensed part. Further, as the condensation continued, the body so formed would be more or less spherical in form, as the conception of our aetherial atom was spherical, and when we conceive of the primary point of condensation, we have to think of a large number of spherical atoms coming together; and, as all the motions of the Aether which give rise to light, heat, electricity and magnetism, and which now include gravitation, are spherical in their operations, so their effect upon any condensing Aether would take a spherical form. Thus such bodies as nebulae, comets, asteroids, satellites, planets and suns should possess bodies more or less of a spherical form, subject to certain qualifying conditions, as rotation and orbital velocity, and this is in harmony with observation and experience. For we shall find that even in the case of nebulae, we have globular, ring or annular nebulae, and elliptic nebulae, while in the case of comets, the nuclei and coma are more or less spherical. Further, it is a familiar fact that the shape of all asteroids, satellites, planets, and even the sun is spherical or that of an oblate spheroid, which latter is simply due to its rotational velocity on its axis. Thus the principle involved in the nebular hypothesis receives its confirmation in the atomic and gravitating Aether, and with certain modifications of the different hypotheses advanced, is capable of uniting all those hypotheses that have ever been put forth in this direction into one perfect and harmonious whole.
