Hey guys, I found a new way to date the great pyramid. Let's use POLAR MOTION to date the Great Pyramid! To my knowledge this has not been done before, with our new measurements of polar motion! The true pole actually moves around, about 10-30 cm per year. So, simply plug this into the distance the Great Pyramid has moved from its former position of 30 degrees north of the Equator. It is now 29.9792 degrees north of the equator! Assuming an average movement of 17 cm per year we get 19,588 years. 1 degree is 111 km! It's also clear the Giza builders knew the size of the earth. In khufu's time they probably did not know the size of the earth!
