The mystery of the Pyramid of Cheops
There are a lot of mysteries connected with one of the greatest pyramids that is the Pyramid of Cheops. It was built from the stones of almost the same weight. Almost all of them have 2.5 tones. They are put perfectly in horizontal way without any mistake and made the perfect monolith.
It was simply impossible to make such stones using the copper instruments of that period. They couldn't even make the stone that would be similar to these ones. Moreover it is unknown how Ancient Egyptians managed to elevate and to put these stones on such height. Some scientists say about 20 thousand of slaves others say about the same number of free people. But it wouldn't be real to elevate these blocks even using 100 thousand people.
The official version explains it by the fact that Egyptians had the sand embankment to the top of pyramids with the help of which bricks were brought to the top. But in such case the embankment would be ruined by its own weight.
Besides it is also interesting how they made these stones from the material situated at the distance of several tenths of kilometers from Giza. Such transportation must leave at least some traces but nothing was found there. And among the stone quarries undone bricks were found. They are 50-meters giant columns the saw cuts of which remind the saw cut of the laser that is the modern way of work on the stone.
