Did you guys know that the Pyramids at Giza are not only like the biggest burial tombs for Pharaohs but also observatories? Roughly 5000 years ago, the Egyptians (or some people say it must have been aliens) built the world’s largest clock. From it, one can tell the time in hours, days, seasons as well as centuries.
It’s the Pyramid of Cheops (26th century BC) which is the largest pyramid and probably the oldest astronomical observatory that exists. Only in 1853, a French astronomer, Jean Baptiste Biot, realised that the pyramid is a giant sundial. On the ground next to the northern and southern facades there were wide level pavements. In winter the pyramid would cast its shadow on the pavement to the north and in summer the highly polished southern façade would reflect a triangle of sunlight on the southern pavement. The pavement blocks had been cut in widths similar to the gradations necessary to indicate the passing day.
Also in the 19th century a British astronomer put forward the theory that the descending passage which leads down to the heart of the pyramid is at an angle that aligns with the pole star. The Egyptian’s pole star was not the same as the present one because of the axis of the earth shifting gradually over the centuries. However if this theory is correct, the heart of the pyramid would make a good viewing platform for astronomical discoveries.
Deep stuff eh??
