This Building Shouldn't Be Physically Possible
In 537 AD, Emperor Justinian hired two mathematicians not architects to build the largest structure in the world. They had never built anything at this scale. The dome they created has no visible support. It has floated in mid-air for 1,500 years. And the acoustics inside do something to the human voice that scientists only discovered in 2013. This is the story of how it was built, why it appears to defy physics, and what happens when you stand beneath it. #architecture #architecturehistory #hagiasophia
