A resonance

Say, the mass of the Sun placed in a vacuum void  in the center of other mass forming into spherical mass by the adhesion of the dictates of, the greater mass of the Sun. The Sun sending it's harmonic, dictates to the matter within it's proximity of gravitational mass pull,  where what frequencies hold mass, at a particular junction in ratios to closeness to mass in it's proximity.

Dark matter is really "Dark Brown Honey" because it darkens like seeing through a gel the area behind it and never "Blanks, blacks out or darkens" the view behind it out, it only bends and distorts it, with a dark golden frequency and vibration.
