Just published. On January 4th, 2017 scientists at the CalTech L.I.G.O detected the merger of two black holes 3 billion light-years away. At 2:11:58 a.m. on January 4th 2017 the arms of LIGO’s Hanford, WA interferometer shivered. Three milliseconds later, Livingston’s interferometer followed suit. Even though parts of the U.S. were experiencing record cold temperatures, the trembling wasn’t caused by…
