00:00The Great Pyramids, ancient wonders rising from the sands of Egypt.
00:07But did you know they are aligned almost perfectly to True North with less than 0.05 of error?
00:15No GPS, no compass, yet somehow, thousands of years ago, they knew the direction of True North better than we did for centuries.
00:24Some experts believe the ancient Egyptians used the stars, especially the circumpolar stars, to determine direction.
00:34By tracking the rising and falling of certain stars at night, they could find perfect north.
00:42Others argue they used shadow sticks and the sun's movement during the equinox.
00:46On the equinox, the sun rises exactly in the east and sets in the west creating a perfect line for builders.
00:58Imagine ancient engineers, without modern tools, using light, shadows, and the sky as their guy.
01:05Remarkably, other ancient sites like Stonehenge and Machu Picchu also align with celestial events.
01:11Today, scientists still marvel at the precision.
01:17The Great Pyramid sides are aligned more accurately, and many modern buildings.
01:22Some even believe the alignment connects the pyramids to the cosmos, as if they were built to communicate with the universe.
01:30Whether science or mystery, the pyramids' perfect alignment reminds us, the ancients knew far more than we once thought.
