A whopping 7.5 billion light-years from Earth, two black holes, each about the size of Long Island, rapidly spun around each other several times per second before smashing together in a cataclysmic explosion that sent shockwaves through the Universe. Normally, violent unions like this are dark events, but astronomers think they saw a flare of light emerge from this celestial dance — potentially the first time light has ever been seen from black holes merging.
It’s a unique discovery since black holes are notorious for not producing any light at all. These super dense objects are so massive that nothing can escape their gravitational pull — not even light. So how exactly did researchers see a flare from two black holes that aren’t...
