The Great Pyramid Has Survived 4,600 Years — Scientists Now Know Why

The Great Pyramid has always looked impossible: a 4,600-year-old monument still standing after centuries of weathering, looting, human damage, and earthquakes. For a long time, its survival was explained mainly through awe — huge stones, ancient genius, and the stubborn mystery of Egypt’s most famous structure.

Now researchers have a more technical answer. A new study measured how the pyramid vibrates and found that its shape, mass, internal chambers, and limestone foundation may help it resist earthquake damage. The secret is not one magical feature, but a whole system that keeps the monument stable when the ground moves.
