All kidding aside (for me, anyway), The article about the Great Pyramid being a pump is intriguing. My only experience with pumps has been to replace two sump pumps in my basement, but the author of the article certainly puts a realistic argument out there showing how it could’ve happened.
It still leaves a lot of questions, like what really is in that “void”,anyway?
Sorry, but the pump idea is like the Giza Power Plant idea — it’s imaginative because it’s imaginary.

https://www.quora.com/Ancient-Egypt-Various-sources-claim-that-the-Great-Pyramid-of-Giza-was-a-water-pump-and-theyre-pretty-convincing-yet-the-theory-seems-to-be-ignored-by-mainstream-historians-Why
[snip] What are these convincing sources? Mainstream historians ignore these claims because they are nonsense. Why would the ancient Egyptians living on the securest and most reliable source of fresh-waster in the ancient Near East (ANE) with sufficient water to build one of the largest populations in the ANE and still produce surplus grain for trade need to build a water pump that was miles from a major population centre of the day and that would have required a vast amount of resources to construct? In modern terms this would be tantamount to building a massive pumping station and pipeline in the high arctic to provide freshwater to Toronto sitting on Lake Ontario. [/snip]
[’Civ resumes] A few years back there was a guy who claimed that water was used to raise stones to construct the Great Pyramid, that the stones arrived at a lock at the base, then, thanks to being built into a buoyant structure, floated to the top of a watertight tube, then were slid onto the dry working area, were removed from the buoyant shell, and slid into place. This is also something that “would work” apart from requiring far more work and more laborers than just pulling the stones with brute force, requiring engineering that probably wasn’t available, and, of course, a power source to keep the water standing in a tube, and an explanation for why the Egyptians weren’t still working on the project, since it would require far more time.
The Giza Power Plant idea is that the Great Pyramid generated electricity to run power tools used to build, uh, the Great Pyramid. No trace of any abandoned wiring, worn out high-speed saws and drills, ancient power tools, or ancient testimony, exists.
