Now, they may be closing in on an answer to a puzzle that has stumped them since then: How do black holes pair in the first place? The Laser Interferometer Gravitational- Wave Observatory (LIGO), a duo of huge optical instruments in Louisi- ana and Washington state, and its European partner, the Virgo detector in Italy, have spotted more than 300 such mergers. …
