This is the Great Pyramid of Giza, and it has been around since 2560 B.C.. Believe it or not, there are some areas of it that have not been explored.
In fact, there are two unexplored air shafts that can cannot be searched in the traditional archeological manner. The solution is robots.
This is the Djedi project, a robotic tunnel explorer that can drill through stone and burrow through holes less than one inch in diameter. It also has a mini ultrasonic device that is able to listen to the response to help determine the “thickness and condition of the stone, and a coring drill that can penetrate the rock (if necessary) while removing the minimum amount of material necessary”. Lights and “snake cameras” will help the researchers see exactly where it is going.
This is important because an archaeological expedition in 1992 found a limestone door with two copper handles. After drilling through that door ten years later, they found another door, and they still don’t know what is behind that other door.
It is delicate work, and who knows what could be behind that door. Maybe it is some giant machine that will destroy the sun, like in Transformers: Revenge of the Fallen. Oh, that is just one of the bad things of that awful film. Here’s hoping they find some real treasure.
