The southern shaft targeted Orion’s Belt (Al Nitak) at the construction epoch
At ~2500 BCE the southern shaft of the King’s Chamber pointed at Al Nitak as it crossed the meridian. The declination match is tight using Vondřák long-term precession.
Relieving chambers are structural — their gap resonance is coincidental
The five chambers above the King’s Chamber are load-relief engineering. Their three 1.3 m air gaps do resonate near the chamber’s 2nd width-mode harmonic (66 Hz vs 65.5 Hz), but that’s an incidental coincidence, not evidence of acoustic design.
Mathematical Monument Theory
The pyramid was built to encode and preserve advanced mathematical and scientific knowledge including Pi, Phi, the Earth's dimensions, and fundamental constants.
Astronomical Observatory Theory
The pyramid served as a massive astronomical instrument for precisely tracking celestial bodies, seasons, and precession of the equinoxes.
