Researchers think they've discovered the most massive pair of black holes yet to be caught in this act. ESA In a galaxy 4.4 billion light-years away, scientists may have discovered the most massive pair of black holes ever found. Together, the behemoths have an estimated mass 60 billion times that of our sun, at least double that of next most massive black hole duo. The black hole suspects lurk in a dark region devoid of starlight 3,200 light-years across in the middle of a galaxy called Abell 402-BCG. In 2018, scientists found the galaxy had an unusual void.…
