Unexplained Interior, Great Pyramid (above Grand Gallery)

The Big Void: 30-Meter Hidden Chamber Above the Grand Gallery

Catalogued: February 08, 2026

Full Description

CONFIRMED BY THREE INDEPENDENT MUON TOMOGRAPHY METHODS (2017)

The ScanPyramids project discovered a previously unknown void inside the Great Pyramid at least 30 meters long, located directly above the Grand Gallery. Three independent detector systems (nuclear emulsions, scintillator hodoscopes, gas detectors) confirmed the finding, published in Nature (November 2017).

THE MYSTERY:
- No known passage leads to this void
- Its exact dimensions and contents are unknown
- It is similar in length to the Grand Gallery (~47m)
- Its position directly above the Grand Gallery suggests a functional relationship
- Egyptian authorities have not permitted invasive exploration

IN THE TRANSMITTER MODEL:
A void parallel to and above the Grand Gallery would function as a coupled resonance chamber. Two parallel acoustic spaces (Grand Gallery + Big Void) create a coupled room acoustic system with broader frequency response and higher Q-factor (sharper resonance peaks) than either space alone. This is standard acoustic engineering.

The Big Void may be the most important undiscovered room in archaeology.
