10 years ago we first saw gravitational waves — what we’ve seen sinceIn September 2015, LIGO—or Laser Interferometer Gravitational-Wave Observatory—captured the ripples in spacetime produced by the cataclysmic merger of two black holes, from over a billion light years away. This discovery confirmed Einstein’s hypothesis about gravitational waves and gave astronomers a new way to explore the cosmos. In the decade since, LIGO’s scientific team, including physicist Nergis Mavalvala, has been busy, including new results announced this week confirming a 50-year-old prediction by Stephen Hawking about how black holes merge. Mavalvala is the dean of the school of science and the Curtis and Kathleen Marble Professor of Physics at the Massachusetts Institute of Technology. The latest discovery was reported in the journal Physical Review Letters.What wild killer whales sharing food with humans says about their intelligenceAfter an experience of being offered a recently killed seabird by an Orca, cetologist Jared Towers
