What’s Hiding Inside Egypt’s Great Pyramid? Tiny Robots May Find Out

By Owen Jarus

Using cosmic particles called muons, and possibly tiny robots, scientists hope to figure out what created two mysterious voids inside the Great Pyramid.

Possibilities range from a new burial chamber to a sealed-off construction passage.

Built by the pharaoh Khufu (whose reign started around 2551 B.C.), the Great Pyramid of Giza stands 455 feet (138 meters) tall and was the tallest human-made structure in the world until the Lincoln Cathedral was completed in England in the 14th century.

Scientists with the Scan Pyramids project reportedthe discovery of two previously unknown voids in the Great Pyramid in an article published in November 2017 in the journal Nature. The larger of the two voids is at least 98 feet (30 m) long and is located above a giant passageway known as the grand gallery that leads to Khufu’s burial chamber. The smaller void is located behind the north face of the pyramid and consists of a corridor whose length is unclear. Muon detectors and thermal imaging were used to make these discoveries.
