Scientists using an imaging method based on cosmic rays have detected a large and enigmatic internal structure in the last of the Seven Wonders of the Ancient World still standing, the massive Great Pyramid of Giza on the outskirts of Cairo. The researchers said it constitutes the first major inner structure found in the Great Pyramid since the 19th century. The Great Pyramid, or Khufu’s Pyramid, was built during the reign of Pharaoh Khufu (Cheops), who reigned from 2509 to 2483 BC. The Great Pyramid, looming alongside other large pyramids, is a towering achievement, remarkable for its simple beauty and colossal grandeur. Placing detectors inside a pyramid can discern cavities within a solid structure.
