The Atlantic Astronomers have discovered a black-hole treasure trove that is changing our view of the cosmos. MARK GARLICK / SCIENCE PHOTO LIBRARY / GETTY When the first black-hole collision was detected in 2015, it was a watershed moment in the history of astronomy. Using gravitational waves, astronomers were observing the universe in an entirely new way. But this first event didn’t revolutionize our understanding of black holes—nor could it. This collision would be the first of many, astronomers knew, and only with that bounty would answers come. “The first discovery was the thrill of...
