Hidden "void" found in Egypt's Great Pyramid
Scientists have probed Egypt's mysterious Great Pyramid of Giza with tools of modern particle physics and say they have discovered a hidden "void" within its ancient walls. The large space is roughly 100 feet long and situated above the pyramid's Grand Gallery, according to a report published in the scientific journal Nature Thursday.
Why it matters: The study suggests that modern advances in technology could lead to new discoveries and help create a better understanding of the ancient world — even in well-studied places, like the Great Pyramid, built around 2500 B.C. and considered to be one of the Seven Wonders of the World.
