Two measurements I discovered that support that were of particular interest, for anyone out there who shares my idea of the purpose of the ascending passage and plugs. One was that the angle of the ascending passage happens to be right in the cross hairs of the perfect angle where granite's coefficient of friction equals the downward sliding force. Perhaps that's a known thing.
The other idea that supports this idea was that based on the measurements of the weight of the 3 plugs, (assuming the third was a full piece originally) is approximately 60% of the weight of water that could accumulate in the descending passage between the entrance and the plugs.
I had been noodling around with the idea that there might be a hydrolic system that harnessed the weight of that potential accumulated amount of water to mechanically push up on the granite plug blocks. I have thought of some fairly rudimentary systems that could be made of large beams of wood to act as a sort of jack to transfer the weight of trapped water above the plugs into a sort of cam or lever to push up. My guess is it would work in small increments, followed by a drain out, detach, reset, and refill. Even if the linkages of this system were to be at great advantage to the power of it, with a sacrifice of how far it could push the blocks each time, it still would only take a few days to push those blocks all the way up.
If any of this were possible, it would suggest that when they wanted to replace the plugs, perhaps each time they might line the bottom sections of the chamber with a sort of sealing mud. And once the mud dried it would be a sufficient pressure stop for the system. Maybe with that in mind, it explains why the bottom section of the ascending passage was so worn out, if every time the blocks being pushed up had hardened mud scraping away that lower section.
Everyone here seems far more experienced and knowledgeable about all this stuff so I'm completely fine to hear criticisms. I'm really only a few weeks into taking interest in this stuff. But suffice it to say, I am solidly sold on the concept of the great pyramid being a machine rather than a tomb, and in fact, I'm not really even that surprised by the protection of that idea with the tomb dogma and limited access. There are an enormous amount of religious based cultures in the world that can't be trusted to control the rate of change of their fundamental belief systems without acting in extremely aggressive and destructive ways.
P.S. my main influences on what this system is are a hybrid of these two websites
