Structural grain and refractive density

A natural objection arises. If gravity changes the medium near massive bodies, should its grain, the Planck length, not change as well? RSI answers that this question applies particle thinking to a continuous field.

Since the Eternal Consonance has no particles and no porosity, the Planck length is not a tiny volume or pixel of space. It is a geometric yield limit: the sharpest curve the medium's 0.73 N tension can hold before it violently unzips back to rest.

When matter gathers, it forms a pressure sink. The medium is incompressible, so this does not pack it more densely. Instead it lowers the medium's effective tension nearby. Since the speed of waves is c = √(Ξ / μ), lower tension means slower light, and the resulting refractive gradient is what we observe as gravitation. A slackening of tension does not change the medium's yield limit, however. The Planck length remains the same across the entire toroidal circuit, the same everywhere at any one time. Over the cycle, RSI proposes, this limit grows finer and coarser everywhere at once, like the fold of a vortex that tightens without any change in volume. Because every ruler tightens with it, every local measurement of the Planck length gives the same value in every era (Chapter VI).
