Frozen-In Gravity Model — Asenjo, Comisso & Winkler (PRL 2026)
Extracted equations and their mapping to PIST Extended Encoding.
Paper: "Frozen-In Gravitational Fields"
DOI: 10.1103/6c4q-kx6f
URL: https://phys.org/news/2026-04-frozen-gravity-evolution-spacetime-dynamics.html
Core idea: Gravitational field structures remain "frozen" into spacetime dynamics
under ideal conditions, preserving topological invariants.
PIST analogy: Coordinate structures remain invariant under encoding/decoding,
eliminating the need for search-based context modeling.
