The Giza-Orion correlation theory is a fringe hypothesis claiming the correlation between the design of the Giza pyramid complex and the position of Orion’s belt during the time the pyramids were built.
Some flat-Earthers use the Orion correlation theory to prove that stars never change. They are wrong. The theory already accounted for the shift in the position of the stars due to Earth’s axial precession. The theory was formulated using the position of Orion’s belt when Egyptians built the pyramids, not the current position of the stars.
