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.
Researchers believe the best case scenario would be the uncovering of the hidden burial chamber of pharaoh Khufu, who reigned over Egypt from 2251 BC to 2525 BC, and was the man the pyramid was built for.
A team of researchers behind the incredible find want to use equipment 100x more powerful than the stuff they used for this discovery.
They said: "We plan to field a telescope system that has upwards of 100 times the sensitivity of the equipment that has recently been used at the Great Pyramid.
"Since the detectors that are proposed are very large, they cannot be placed inside the pyramid, therefore our approach is to put them outside and move them along the base.
"In this way, we can collect muons from all angles in order to build up the required data set."
Muons are particles similar to electrons and can be picked up by sensitive telescopes.
The new project to discover what the voids were used for will involve the super sensitive particles which react differently with air and stone and will help map out the inside of the pyramid and reveal any pockets of air.
The Egyptian Ministry of Tourism and Antiquities has given permission for the scans but the team still need funding.
The voids were originally revealed, in less detail, back in 2017 after a two year "Scan Pyramids" project.
Described at the time as a 'deep void', the passage was thought to be least 100ft long and up to 230ft above ground.
The Great Pyramid was one of the original seven wonders of the ancient world, and was once the world's tallest structure at 456ft high and 755ft wide.
Also known as Khufu's Pyramid after the pharaoh who commissioned it as his tomb, Giza is the only original ancient wonder to remain intact - and many details about its purpose and history remain a secret.
It was completed in around 2560 BC and was the tallest man-made structure in the world for more than 3,800 years.
