Spacetime and Gravity

General relativity is not a separate force — it is the geometry that emerges when the CMCA tape minimizes its own description length. Einstein's equations are a theorem about information, not a postulate about curvature.

What you'll understand after this path

Gravity from MDL

How minimizing the description length of the CMCA tape automatically selects the unique gravitational action — the Einstein-Hilbert action — without any additional postulate.

Einstein's equations

Why Gμν = 8πGN Tμν is a theorem about information density, not an axiom about curved spacetime.

Newton's constant

How GN is derived from the orbit combinatorics of the Frobenius group F21, matching measurement to 0.04% with zero free parameters.

Lessons

Gravity from Description-Length Minimization

How the metric structure of spacetime arises from MDL applied to the CMCA tape, why particles follow geodesics as a theorem, and how Newton's constant is derived from F21 orbit combinatorics at 0.04% accuracy.
