The correlation between the Giza Pyramids
 and Orion's belt

This is an aerial picture of the Memphite Necropolis Site at Giza, south-west of Cairo. Look carefully at the way the Pyramids are aligned. At first glance they seem to be imperfectly positioned. Classical Egyptologists maintain that this was either a mistake or a result of the terrain in the Giza Plateau. Compare this to the image of the Belt Stars of Orion and things become a little clearer. Far from being a mistake, the Pyramids are aligned almost exactly as the Belt Stars

Although Virginia Trimble and Alexander Badawy first noticed that the "air" shafts in the King's Pyramid pointed towards the constellation of Orion, Bauval was the first to notice that the alignment of the Pyramids was a very precise mirror image of the Belt Stars of Orion. He called this the Correlation Theory, which forms the backbone of his current research.
