00:00The Great Pyramids of Egypt, ancient, massive, and shrouded in mystery.
00:08Standing for over 4,500 years, the Great Pyramid of Khufu weighs over 6 million tons and consists
00:15of more than 2 million stone blocks. Each block weighs up to 2.5 tons yet they were placed with
00:21astonishing precision, without modern cranes or machinery. How did a civilization without iron
00:28tools or wheels manage this colossal feat? Some believe wooden sleds and manpower moved
00:36the stones, aided by clever engineering and ramps. Straight ramps, spiral ramps, or internal
00:45ramps, the debate continues among experts. Even more puzzling the internal chambers and
00:52shafts, or align with incredible accuracy. The pyramids are perfectly aligned to true
01:00north, and may even mirror the stars of Orion's belt.
01:05Were they just tombs, or part of something bigger? Some suggest they were part of a global
01:11ancient knowledge system. Modern engineers admit they'd struggle to replicate the Great Pyramid
01:16today with the same precision and scale. No blueprints had ever been found. The secrets
01:22of construction were likely passed down early or lost forever. So how did they do it? Until
01:29new evidence emerges, the Great Pyramid remains one of humanity's greatest mysteries.
