Everything is vibrational, and can be categorized as having specific types. All vibrations have a frequency. Light, or electromagnetic radiation, is vibratory, and each type of electromagnetic radiation has a specific frequency that moves along the electromagnetic spectrum. Yet light is only one small vibrational type of a larger, multidimensional vibratory spectrum. Gravity, compounds, and even consciousness have their own vibrational types, adhering to their own spectrum. The periodic table of elements, for example, is the atomic spectrum. Any vibrations in harmonic proportion are attractive, and any vibrations in discordant proportion are repulsive.
The transverse wave model currently used to describe electromagnetic radiation is not quite accurate. All vibration - from sound, to gravity, to atoms - is better described as ether perturbations propagating in a longitudinal wave fashion. Rather than compression and rarefaction, a vibration better resembles cavitation and radiation. Cavitation, or implosion, is the charging “compression” aspect of a vibration. The increase of counter-space creates a voidance: electric. Radiation, or dispersion, is the discharging “rarefaction” aspect. The field ether pressure of space: magnetic.
The frequency of vibrations is currently measured against time, though vibrations are actually speed-based, with the ether being the relative reference frame. Time is a manmade construct - it is relative. Gravity, time, space, and the speed of light are in no way constants. The ether from which all vibratory particles originate is the only constant giving relativity to everything else and must be considered in all interactions.
