Gravity as a variable speed of light
RSI explains gravity as a variable speed of light set by the tension of the medium, matching General Relativity's mathematics with a physical cause.
RSI holds that curved spacetime dimensions are not required to explain gravity. Gravity can instead be described as a Variable Speed of Light (VSL) phenomenon, in which the speed of light depends on the tension of the medium it crosses.
In General Relativity, measuring rods shrink and clocks slow in a gravitational field. RSI gives the cause: near a mass the medium's tension slackens. Both accounts produce the same mathematics. RSI proposes that it also explains why the mathematics works. The gravity shadow of a massive object forms a large lens of slackened Consonance that physically refracts the light wave.
The theory holds that this view resolves a conflict between two major theories. Quantum mechanics requires a background, while General Relativity removes one. In RSI, gravity is the hydrodynamics of the Eternal Consonance. It bends light by slackening a physical medium, not by warping a geometric stage.
