Archaeologists Revealed the Lost Technology That Cut Egypt’s Granite — And It Changes History

in this video, we talk about mysterious ancient stonework in Egypt, from a spiral groove on a granite core in London to the unfinished obelisk at Aswan and the massive granite boxes hidden beneath Saqqara, and how each one raises questions about the tools, methods, and precision behind their creation. we also discussed the debate over whether these marks were made by abrasive sand and copper tools or by something more advanced, the experiments of Denys Stocks, the disputed claims around Core 7, and the bigger idea that an advanced craft tradition may have existed, then been lost over time.
