How Pyramids Were Formed!

There are 138 pyramids discovered in the country Egypt. Most of them were built as the tombs for the country’s Pharaohs and their families.
The oldest Pyramid found is the Pyramid of Djoser which is believed to be constructed between 2630 BC – 2611 BC and was built during the third dynasty. Other Pyramids of Egypt were also built centuries ago. Egyptians buried the dead bodies of their Pharaohs with everyday goods and lots of expensive jewelry. They believed that Pharaohs will use them in their afterlife.

From all of these, Pyramids of Giza and Sphinx are the most famous. These are shown in many international movies. Several pyramids of Giza are among the World’s largest structures ever built. The Pyramid of Khufu at Giza is the largest Egyptian Pyramid. It is one of the Seven Wonders of the Ancient World. These are considered as one of the oldest monumental structures ever built. These massive pyramids are built with extraordinary perfection. It is estimated that thousands of workers gave contribution in their construction.
For more than 3,800 years, Great Pyramids of Giza were the tallest man made structure in the world with the height of 146.5 meters (481 feet). Huge blocks of stone were used in the construction of these. But the big question is that how they were formed? This question has puzzled people for centuries. It was not until modern scientists found strong evidence that we are able to have an idea about their construction.

Here’s the proposed theory:

For the construction of these massive Pyramids, ancient Egyptians had to transport massive blocks of stone and statues across the desert. As nearly 4,000 years ago, there was no technology which could help them to make their work easier. As in the desert, it becomes very difficult to moved heavy objects. How did they move such heavy stones over long distances?

Now the mystery of the construction of Pyramids is solved. The Physicists of the University of Amsterdam investigated about how they moved massive stone blocks across desert. Ancient Egyptians moved the massive stone blocks across desert by just wetting the sand in front of the sled on which stones are present.  The force required to pull heavy sled on desert decreases significantly because of the reduction in friction and makes it easier to operate.
The researchers got clues from the wall paintings which were discovered in the ancient tomb of Djehutihotep, which dates back to about 1900 B.C., shows 172 men pulling the statue using ropes attached to a sledge. In the drawing, a person can be seen standing in the front of the sledge and pouring water over the sand.

When researchers did this experiment then they surprised that friction decreases to half which helps the ancient Egyptians to move those heavy blocks of stones.
