"Gravity is not subject to time or space. It pervades the Universe without reference to time or space, instantaneously and without intermission. It is, however, a sympathetic flow, proceeding from the molecular or mass neutral centers to the earth's neutral center with a power corresponding to the character of each individual molecular mass." He [Keely] believed gravity dependent on the medium of the polar stream, for he says "If the sympathetic negative polar stream were cut off from the earth the molecular neutral centers would float away into space like a swarm of bees."

"Under my system the gravital flow comes under the order of the "sympathetic concordant of the ninths" and is that third of the triune combination called the "polar propulsive." Gravity is polar propulsion while magnetism is polar attraction. Both magnetism and gravity can be accelerated by proper vibrations."

He believed gravity to be the result of a law which provides for a reversion of attraction in repulsion, and which acts by transmission of force under immense etheric vibration through the "interetheric subdivision." He also showed that gravitation acts "as a lever." MacVicar states "Every individualized object assimilates itself to itself in successive moments of its existence and all objects tend to assimilate one another." Keely says "Gravity is an ever existing eternal force, coexistent with the compound etheric or high luminous (seventh subdivision) since it entered into, and is an inherent property of, all forms of aggregated matter from their birth. It is the source from which all matter originated and each substance-unit or neutral center is a concordant link, attractive and dispersive, to all other neutral centers. Each neutral center is the nucleus of what we recognize as substance and is potentially the nucleus of a planet."

"The sympathetic concordants (planetary vibrations) established by the Infinite One from the birth of the planetary neutral centers, are simply the operation of the laws of gravity. The inaudible atomic, etheric and interetheric vibrations, which control and direct the movements of the Universe, must of necessity from the magnitude of their result, be the most powerful of all sounds." These vibrations collectively constitute the "Music of the Spheres" discovered by Pythagoras of old and so long considered merely a poetic fancy. This is now proved experimentally in Keely's workshop to be an actual fact.

He calls all planetary masses "terrestrial" and says the "celestial concordant sympathetic vibrations between the spheres govern their motions in their orbits, that at their maximum distance the attractive forces assume supremacy, bringing them toward each other, and at the minimum distance, the repulsive forces assume control causing them to again recede from each other.

Molecular terrestrial masses, composed of the "ultimate ether" bound latent in substance, are sympathetically drawn to the earth's neutral center according to the density of their molecular aggregation, from which must be deducted their celestial sympathetic outreach. In other words, molecular weight consists in the difference between these forces. Either one can be intensified by polar or antipolar vibrations, giving either one predominance. If the celestial (repulsive) predominates, the mass will rise, its velocity proportionate to the concentration of the dominant or the "negative thirds of its mass chords" inducing high neutral radiation together with "celestial attraction." The "terrestrial propulsive" and "celestial attractive" cause ascension and the "celestial propulsive" and "terrestrial attractive" cause descension or increased weight.
