GIZA, EGYPT — Archaeologists have identified an empty cavity in Egypt's Great Pyramid, marking the first discovery of a new internal structure in over two hundred years. <br /> <br />BBC reports that a nearly 100-foot long void was discovered inside the Great Pyramid in Giza, just above the 153-foot long Grand Gallery. <br /> <br />The void was detected using cosmic ray muons, which are high-energy particles that shower the Earth. Muons pass through empty spaces easily, but can be absorbed or deflected by dense materials like solid rock. <br /> <br />Three different muography technologies used to measure muons in the pyramid all detected the same void in the same position. <br /> <br />But because the technique is low resolution, it's difficult to determine the exact shape or function of the void. <br /> <br />Researchers speculate that the void could be one large empty space, or several small ones, possibility used to relieve pressure on the chambers below. <br /> <br />The void will need to be investigated further if we want to know what it actually is. Scientists are already considering drilling a small hole and sending in a tiny robot to hopefully get some answers.
