Core 7 Drilling Techniques and Mysteries

The video explores the mystery of Core 7, a 4,500-year-old granite cylinder from ancient Egypt. Discovered by Flinders Petrie, it challenges our understanding of ancient technology. The core's precise grooves suggest advanced drilling techniques, possibly involving diamond tools, which contradicts known historical records. Modern comparisons show the core was made with greater force than today's power drills, raising questions about the existence of an unknown advanced civilization.
