Some curious comments about the Great Pyramid

Abstract

The Great Pyramid of Egypt was one of the seven Wonders of the ancient world, still standing imposingly in the eyes of the astonished travelers who are heading to the cradle of Egyptian civilization. It is one of the oldest structures built on earth and is considered to be the best built.
The joints of its components are 1/50 of an inch, which is an incredible human work, especially if you consider that it is composed of more than two million stones, some of which weigh less than a ton, however, there are others that weigh two and a quarter tons and many of them up to 20 tons.
The Pyramid covers approximately 13 acres of land, and its construction is solid, unlike pyramidal hollow or filled buildings such as those in Central America.
The Great Pyramid is located very specially on the face of the earth; Joseph Seiss and others have shown that the pyramid is located at the center of gravity of the continents. It also lies at the exact center of the world's land area, dividing the land masses into four equal loaves.
The North-South axis, 31 degrees east of Greenwich, is the longest meridian; The East-West axis, 30 degrees to the north, is the longest parallel in the world. Obviously there is only one point where they cross and it is precisely the place where the Great Pyramid is built.
