Always said the Pyramids were a honeycomb inside. That would lend to all kinds of leverage possibilities.

The interesting thing about the microgravimetric study the French team did about 20 years ago is, they didn’t publish the graphic shown above, probably because no one had anticipated a ramp, and they didn’t want to look incompetent. Makes the rest of the study look a bit lame, although they did discover a previously unknown chamber, which was drilled into, but otherwise unexamined.
