They say that the pyramids are both a calendar and a clock, that is, two in one. Also, in the spring the pyramids have no shadow. Until now, experts could not understand how the Egyptians achieved such an effect.
Still, scientists have figured out why the pyramids are called diamonds in the middle of the desert.
The fact is that the pyramids were originally made of stone and polished with limestone. As a result, these structures were white, and the sun’s rays reflected from the smooth surface of the pyramids gave them shine. Moreover, this brilliance could be seen from far away.
