The Precession Filter: Why Giza Cannot Be a Stellar Transceiver

CRITICAL ANALYSIS INSIGHT

Earth's axial precession (25,772-year cycle) causes stellar positions to drift ~1° every 72 years relative to the horizon. The four star shafts in Khufu's pyramid were precisely aligned to Sirius, Kochab, Al Nitak, and Thuban ONLY around 2500 BCE.

LOGICAL CHAIN:

1. If the shafts were primary operational inputs, the device has a maximum functional lifespan of ~1,000 years.
2. Every other component (bedrock, chambers, aquifer, Schumann) operates on timescales of millions of years.
3. No rational engineer builds a device where 95% of components last forever and 5% fail after 1,000 years — unless those 5% are NOT operationally critical.
4. THEREFORE: the star shafts are non-operational features — most likely construction date markers encoded in geometry.

This eliminates ALL "stellar transceiver" models (including the original Lithic IC v1 antenna interpretation) and forces the conclusion that the system's primary energy source must be omnidirectional and precession-proof: Schumann resonance, seismic microseisms, geomagnetic field, and tidal flexure.

The Queen's Chamber shafts being SEALED — never reaching the exterior — provides physical confirmation. You don't seal an antenna. You DO seal a geometric reference that only needs to encode an angle, not transport energy.
