Could the Great Pyramid of giza be hiding a great secret? Scientists recently discovered what appears to be a huge empty space within the ancient structure—and it may hold clues about how the pyramid was built.
The Great Pyramid—one of the Seven Wonders of the Ancient World—was built in Egypt about 4,500 years ago by the pharaoh Khufu. Ancient Egypt’s kings often built pyramids as tombs and monuments to themselves. (The Great Pyramid contains both a king’s burial chamber and a queen’s, though no mummies have ever been found there.)
