For the first time ever, humans have observed light and gravitational waves from the same event, a neutron star collision 130 million light years away. Thanks to advance warning from the Laser Interferometer Gravitational-Wave Observatory (LIGO), roughly 70 observatories from every continent on Earth, including Antarctica, managed to tune in to watch the merger. Based on this first-ever “multi-messenger” event, thousands of scientists are now making breakthroughs about the behavior of neutron stars and the origin of elements like gold and uranium.…
