Knot-density lensing

General relativity explains gravitational lensing, the bending of light around massive objects, as the warping of space. RSI calls it field refraction caused by changes in knot-density.

In RSI, light is a high-frequency ripple in the Eternal Consonance. When it passes through a region dense with matter-knots, such as a galaxy cluster, it travels through a field clogged with inversions. These knots act like impurities in the medium. They raise its opacity and slow the ripple, producing a refractive index much like that of glass in a lens.

The theory makes a specific prediction. In regions of high turbulent flow, where matter is being inhaled or exhaled at extreme speeds, lensing should exceed what mass alone predicts. RSI proposes that measuring the gap between mass-predicted lensing and observed refraction would map the actual density shadows and fluid currents of the medium.
