A team at Chicago’s Field Museum has published a first-of-its-kind study analyzing 10,000 years’ worth of wealth disparity across six continents. The results, published on April 14 in the journal PNAS, contradict many longstanding assumptions about inequality’s inevitability and how societies organize over time.

Astronomers had never witnessed a black hole “wake up” in real time—until now.

Exactly what caused the collapse of the mighty Roman Empire has been hotly debated practically since the fall itself. Was economic stagnation primarily to blame, or was it societal decay?
