New Petrie's Core Analysis DESTROYS Everything We Know About Ancient Egypt | Adam Young, Karoly Poka (Danny Jones)

Petrie’s Core analysis gets a fresh, no-hype look—what do the grooves and taper actually show?
Adam Young and Karoly Poka walk through measurements, photos, and simple tests to re-examine this famous granite core.

In this episode, we revisit Sir Flinders Petrie’s puzzling “Core 7” and the viral claims around it. Adam and Karoly explain what we can see (helical lines, changing groove depth, taper) and what those details might mean for how the core was drilled. You’ll see clear visuals, step-by-step reasoning, and plain-language takeaways—no jargon required.

We compare possibilities side-by-side: copper tube with sand abrasive vs. harder modern bits, steady feed vs. wobble, and how wear can change the pattern. You’ll learn why consistent measurement matters (diameter, pitch, and roundness), how lighting can make marks look dramatic, and where error bars belong so we don’t overclaim.

Most important, we separate questions from conclusions. What does the evidence strongly support? What still needs lab tests? And what would a fair replication look like? By the end, you’ll have a grounded view of Petrie’s core and a better framework for judging “ancient tech” videos anywhere on the internet.
