Giza Pyramid and 4 mysteries humanity cannot yet decode

As one of the seven original wonders of the ancient world, the Giza pyramid has fascinated people for millennia.
The massive Great Pyramid was built for Pharaoh Khufu.

The massive Great Pyramid, built for Pharaoh Khufu and completed around 2560 BC, is the only one of the Seven Wonders of the Ancient World still intact. Located on the outskirts of Cairo, Egypt, this complex has a total of 6 pyramids, 3 towering pyramids (Khufu, Khafre and Menkaure) and 3 smaller pyramids, plus a giant Sphinx statue. Giant is an attractive destination for tourists. Giza pyramid diagram
Several thousand years on Earth still have not revealed all the secrets of the Pyramids. Built from 2.3 million tightly bonded stone blocks with a total weight of 5.9 million tons. In particular, each block of stone weighs from 2-30 tons, some even weigh 50 tons. Until now, scientists still cannot understand what means the ancient Egyptians used to transport and build such a large structure. In addition, the Giza pyramid complex also has geographical challenges that astronomers cannot decipher.

Located in the center of the Earth continent
The Giza Pyramid is located at the intersection of the longest meridian and longest latitude

Many consider the Great Pyramid of Giza to be one of the oldest, greatest, and most perfect "scientific monuments" on Earth, created thousands of years ago. It is not only an architectural and engineering wonder, but also a geographical wonder because the Giza Pyramid is located at the intersection of the world's longest meridian and longest latitude line

.Located directly with the belt of the constellation Orion

The pyramids of Khufu, Khafre and Menkaure form a perfectly straight line on the ground. At the same time, they are also aligned with the three stars that make up the constellation Orion's Belt. This hypothesis was first proposed by Robert Bauval in 1983. According to computer models, the Great Sphinx and three Pyramids at Giza are compatible with Orion's belt in 10,450 BC. American archaeologist and engineer Glen Dash came up with another, simpler idea. His research suggests that the Egyptians around 4,500 years ago may have used the Autumnal Equinox to achieve that perfect alignment.The Autumnal Equinox is considered the time that appears twice in a year (Spring and Autumnal Equinoxes), when the plane of the Earth's equator passes through the center of the Sun's disk, and the length of day and night are relatively short. equal. Equinox measurements were previously considered a dispensable method of alignment, as it was thought that it would not provide sufficient accuracy. But Glen Dash's work has shown that there is a way that using the equinoxes could work - using the gnomon - the sundial column. To discover this, Glen Dash actually performed his own experiment, starting on the first day of the 2016 Fall Equinox - which falls on September 22, 2016 - and used a gnomon to create a shadow.
The archaeologist tracks the point of the shadow at regular intervals, forming a smooth curve connecting the points together. And at the end of the day, with a piece of taut rope wrapped around the pole, Glen Dash blocked two points of the curve and created an almost perfectly straight line running east-west. This is also known as the Indian circle method. See it in action in the image below:Glen Dash points out that the level of error is similar to the small error found in the alignment of the pyramids of Khufu, Khafre and Menkaure at Giza. The trial was conducted in the US state of Connecticut, but Glen Dash said the same thing would work in Egypt. In fact, all the ancient Egyptians needed to align the pyramids on a clear, sunny day, Glen Dash explains. He added that the Egyptians could calculate the autumnal equinox by counting 91 days forward from the summer solstice.
Although research by an American archaeologist devoted to Egyptian pyramid studies suggests that this technique could be used to align the alignment of pyramids, we still don't have any solid evidence that the ancient Egyptians did so. "Unfortunately, the Egyptians left us very few clues. There are no technical documents or architectural manuscripts that give technical explanations that demonstrate how the ancient Egyptians aligned any any of their temples or pyramids," Glen Dash wrote. While we may never know what actually happened, this hypothesis raises an interesting point - that something as simple as mapping shadows during the Fall Equinox could be sophisticated enough to arrange some of humanity's most recognizable ancient structures
