The Great Pyramid of Egypt is one of the world's oldest and most perplexing enigmas. Writers Robert Bauval and Adrian Gilbert claim that, far from being simply a royal tomb, it was an instrument of worship in the stellar cult of the fourth Egyptian dynasty, and that the precision with which it was constructed was an attempt to re-create heaven on earth. UPUAUT, a tiny precision-made, remote-controlled robot was sent into the shafts to explore and it discovered a door hidden from view for more than 4,500 years.
