A new study showed a complex and vast underground structure under the pyramids in Giza. Scientists from the University of Pisa (Italy) and the University of Stratchaid (Scotland) have checked the area under the Hefren pyramid using the radar -layer with synthetic aperture (SAR). The underground system lasts under all three monumental buildings about two kilometers.

Hyfren Pyramid is the second largest building on the Giza plateau after the Cheops pyramid. Scan shows five identical structures similar to its basis. They include some levels and are connected by geometric paths.
Scientists revealed vertical cylindrical wells down 648 meters and merged into two large block structures. The edges of these structures reach 80 meters long.
The purpose of these structures is not known. Many researchers believe that the pyramids not only serve Pharaoh's tombs. According to one version, they accumulate the Earth's energy.
The project group noted the importance of archaeological excavations under the pyramids. However, the Egyptian government should allow them. The country has a limitation for soil works that can damage ancient buildings and ARXIV reports.
Before The Egyptian pyramids revealed a mysterious energy. Scientists in the framework of the experiment were subject to the great pyramid in Giza's influence of electromagnetic waves. It turns out the centralized structure and enhancing energy around the facility and in certain rooms. According to scientists, the pyramid can be a huge power plant. But during construction, people do not know about this type of energy.
