The French man devoted his life to figuring out how the Great Pyramid was built...quit his job and everything. He was almost out of money, but had a revolutionary idea when a French software (if you want to call it that) funded him.
His idea was that the pyramid was built using an internal ramp.
The base of the pyramid was build using the common single ramp idea. Once the base was complete, the rest of the pyramid would be completed using a large tunnel that spiral within the pyramid itself. Stones used to build the initial outside ramp were then used for the rest of the pyramid. Using a 7 degree slope, he graphically put his idea to test. He wanted to see if the ramp inside would intersect with any known chambers or tunnels and found that it didn't.
Also, the King's Chamber has a flat ceiling, made with multiple layers of granite. The large vaulted grand gallery was actually used as a counter-weight slope. Using this counter weight system, a large weight (on many rolling logs) would help with the pulling of stones up the outside single ramp. He found a lot of evidence to support this. There is scarring in the way of lines from massive stones inside the grand gallery, as well as an old stone (now repaired to look square) that had a v-shaped groove in it where the rope would have been. The ceiling itself in the Grand Gallery was also very high for room for other ropes and things of that nature that helped in moving these granite ceiling stones.
Now, there are some questions that came up with this idea.
1) How did the pullers manage to make 90 degree turns in the spiral tunnel ramp? His idea was that they didn't initially complete the corners of the pyramid, and that they actually were open. These open corners also provided air and light to the inside. Also, cranes were used to turn the stones for the new direction.
2) How come no "sonar" evidence showed the existing tunnels? Well, in the 1970s (?), a group did testing to try and find more hidden chambers and passageways, with success, but never found this so called tunnel. However, all these years later, a man from that group came to this French guy and wanted to show him something. It turns out that they did find something that perfectly overlapped where the tunnels should be, but because of their location and spiral shape, the group thought it was an anomoly.
When the sun is shining right, you can actually see diagonal lines at perfect 7* slopes on the outside of one side of the pyramid, exactly where the tunnels should be.
I have a bit more on this, but my computer is going to die. I also can't remember all the details off the top of my head, but the show is interesting, and if you have On-Demand for your TV, see if you have it under the NatGeo section.
Anyone hear this theory before? Is this flawed? Any other comments or questions?
