Scientists Noticed Something Strange About The Great Pyramid of Giza

The Great Pyramid of Giza, one of the seven wonders of the world, is a bit lopsided, scientists said.

Researchers from the U.S.-based Glen Dash Research Foundation and the Ancient Egypt Research Associates (AERA) scanning and mapping the Giza pyramids found the structural error in The Great Pyramid of Giza, known to be one of the world's most majestic and well-built ancient structures.

According to scientists, the west side of the pyramid is slightly longer than the east side, creating a base that is not perfectly square. This discovery sheds light to some of the methods used by the ancient Egyptians in constructing these pyramids.

Pyramids used to be encased in white limestone back when they were first constructed 4,500 years ago. Over the years, the limestone outer layers were stripped off and the result is the pyramid form we are seeing today.

"Most of those casing stones were removed centuries ago for building material, leaving the pyramid as we see it today, without most of its original shell," Glen Dash, head of the Glen Dash Research Foundation, said in a report published on Science Alert.

Without the outer layer, the researchers used a new measuring technique that involved finding any surviving remnants in the casing to see where the original edges had been. The researchers then plotted these points on a grid and calculated the lengths of each side.

The scientists found that the west side was 5.55 inches longer than the east side, making the structure look slightly tilted to one side.

"We can only speculate as to how the Egyptians could have laid out these lines with such precision using only the tools they had," Dash said.

According to Dash, the Egyptian builders would have likely laid out the pyramid's design on a grid and applied it to the ground during construction. However, they said that more research needs to be done to figure out how this could have worked.

More discoveries were being made about ancient Egyptians. Just recently, researchers from Italy discovered that Egyptian pharaoh Tutankhamun's dagger was made of iron taken from a meteorite.
