Hidden voids in the Great Pyramid of Giza could be the secret chambers of a pharaoh's tomb, a high-powered scan has revealed more than 4,000 years after it was built.
The ultra-powerful scan has proven there are two hidden voids inside the largest man-made pyramid on Earth, and now archaeologists are planning to get a better look inside with better technology.
The largest of the two voids is 98 feet long and 20 feet wide and archaeologists are hoping new scans will uncover what the mysterious voids were used for.
