History's Greatest Unsolved Engineering Mystery

[00:00:00]Did you know the pyramids of Egypt are older than you can possibly imagine? The Great Pyramid of Giza was built over 4,500 years ago. It was the tallest structure on Earth for nearly 4,000 [music] years. Nothing surpassed it until the Eiffel Tower in 1889. And here's what nobody talks about. We still don't fully know how they built it. Over 2 million stone blocks, some weighing [music] 80 tons, moved without wheels, without cranes, without modern machinery of any kind.

[00:00:28]The blocks fit together so precisely you cannot slide [music] a piece of paper between them, even today. And the alignment, the Great Pyramid is oriented to true north with an accuracy of 0.05°.

[00:00:36][music] More precise than the Greenwich Observatory in London, built thousands of years before modern tools existed.

[00:00:43]Here's the part [music] that quietly breaks your brain.

[00:00:45]Cleopatra lived closer in time to the moon landing than she did to the construction of the pyramids. The pyramids are that old. We have satellites, [music] we have AI, we have technology beyond anything history has seen, and we still argue about how they were built. Some mysteries don't get solved, they just get deeper.
