Because they thought their pharaohs became stars in the northern sky after death, the ancient Egyptians positioned their pyramids and temples to the north. The Great Pyramid, however, is aligned with the north, whereas the smaller pyramids are all slightly off. Stars do not remain in the same location year after year. Thus, the alignment of these structures should be considered a myth.
The idea of an alignment between the pyramids and the stars comes from two sources. The first is a papyrus document called "The Pyramids of Egypt" by John Taylor. The second is a book called A Popular Account of the Ancient World, written in 1819 by Charles Wheatstone. Both authors believed that the pyramids were built by the pharaohs as astronomical observatories where they could monitor and record solar and lunar eclipses. They also thought that the king would be provided with a view of the night sky through large openings in the pyramid roof.
However, modern scientists believe that the pyramids were used for more practical reasons. They were constructed out of rock without any metal available in Egypt at that time. The main ingredient for making weapons or tools would have been hard to find on site, so the pharaohs must have had a reason for building such large monuments. They probably wanted to show themselves to be powerful leaders who could provide for their people after they died.
Also, there are no windows or other openings in the walls of the pyramids.
The celestial north pole was discovered exactly between the two stars in 2467 BC. Until then, people believed that the Earth was flat, with the center of the world at the center of the earth. They also believed that the world was static, without movement or change.
In this case, "north" meant east. If you go to Egypt today, you'll see that the pyramids are still pointing to the north, because people there still believe that the sky is empty and nothing will stop them from putting the pyramid where they want it to be.
The first pyramid was built for King Chephren around 2500 BC. It was made of limestone and covered with smooth plaster. Today, only small parts of the original structure remain. The second king to have a pyramid was Khufu (also called Chephren). His pyramid is larger than the one of his brother Chephren and it's made of rock coated with black granite. It's one of the biggest buildings in history, covering about 513 feet long, 228 feet wide and 220 feet high. It remains one of the largest buildings without any kind of support, except for the air.
The four cardinal points of the compass are exactly aligned with the four faces of an Egyptian pyramid. Given that the Egyptians never identified a north pole on Earth, they could only have done so by rotating the sky around the North Celestial Pole. Therefore, all the pyramids were built using the knowledge that they would one day be able to point toward the north celestial pole.
Also, if you look at a map of Egypt, you'll see that the country is shaped like a pyramid with its apex in the middle. This is because the Pharaohs were also worshipers of Ra, the sun god. They believed that he wanted to take up residence in a human body and, therefore, needed a physical home where he could be worshipped daily. Hence, the shape of ancient Egypt.
Finally, it should be noted that some scholars believe that the Great Pyramid was not intended to be a tomb for King Khufu but rather as a monument to himself. If this is true, then it proves that the Pharaohs were not afraid to put themselves on display for all to see.
Each side of the Great Pyramid rises at a 51.5-degree inclination to the summit. Furthermore, each of the sides is virtually precisely aligned with the real north, south, east, and west. The pyramid's sides are also aligned with the four points of the compass.
The two smaller pyramids at Giza exhibit similar characteristics; they are aligned with the true north-south axis and the horizon. These results indicate that the Egyptians may have had accurate astronomical instruments at their disposal, or perhaps they simply knew how to use them properly. Either way, it shows that they were aware of the importance of using astronomy to find directions in life and could have used this knowledge to help guide the construction of their great monuments.
Angles are one of the three main topics in plane geometry. An angle is formed when two lines or planes meet. There are seven types of angles: zero degrees, 90 degrees, 180 degrees, 270 degrees, 360 degrees, 450 degrees, and 540 degrees.
The three pyramids represent the three stars in Orion's belt; the Sphinx represents the constellation Leo; and the Nile represents the Milky Way. Other ancient societies shared the idea of establishing a holy setting on Earth that mirrors the night sky. In Israel, this site was called Eqbal (or Calah) because its location mirrored the constellation Coronae Australis.
Modern scientists also use monuments and other structures to help understand our galaxy and the places in it where new stars are born from material left over from previous generations of stars. For example, astronomers know that stars are born in clusters called open clusters or in the space between galaxies called galactic voids. They can tell what type of star cluster or void a galaxy is using light from its red giant branch stars which are evolving into white dwarf stars. This is done by comparing the color of these stars with those of similar stars in different parts of the galaxy or cluster. Similarly, they can estimate how far away a galaxy is by measuring the distance of its brightest stars. These methods depend on knowing the position of the stars within the galaxy or cluster. That's where markers such as pyramids are useful because they fixed in time and space. Open clusters tend to be found near their birth sites so archaeologists can learn about past civilizations by studying these objects.
