Fossil Causal Geometry as the Common Origin of Gravitation and Quantum Mechanics - Effect without Cause

Fossil gravity theory derives General Relativity (GR) and quantum mechanics from a singleaxiom: causal order is information density order. Zone 0 - a metric-free causal structure - isthe common framework of both theories. GR and quantum mechanics appear as limitingcases of different node densities. The fossil field equation extends the Einstein fieldequations by two terms from Zone 0. All parameters of the Standard Model follow withoutfree parameters. The theory is falsifiable via LIGO O4, DESI DR3, and Euclid.
