Mystery Of How Egyptians Built Pyramids May Have Been Solved

Radar satellite imagery was used by researchers to map the river branch.

A group of researchers has finally found a long-buried 64-kilometre-long river branch of the Nile River. It was hidden under desert and farmland for millennia, according to a study by the University of North Carolina Wilmington.

The study added the river branch used to flow alongside the 31 pyramids in Egypt. It also stated that the river was used to transport giant stone blocks. The latest discovery, in a way, has also explained the reason behind the construction of pyramids in a chain between 4,700 and 3,700 years ago.

Radar satellite imagery was used by researchers to map the river branch. Eman Ghoneim, the University of North Carolina Wilmington earth and ocean sciences professor, told the news agency AFP that the radar gave them the "unique ability to penetrate the sand surface and produce images of hidden features including buried rivers and ancient structures.”
