By Michael Tabb in Livingston When LIGO announced in 2016 that it had discovered gravitational waves, something Albert Einstein predicted in his general theory of relativity, it was a breakthrough moment for astrophysics. The discovery made front-page news, the scientists behind it won the Nobel Prize, and the waveform of two black holes colliding made it onto a t-shirt featured on The Big
livescience.com By Paul Sutter, Astrophysicist | March 1, 2019 07:52am ET The governing theory of particle physics explains everything about the subatomic world … except for the parts that it doesn’t. And unfortunately, there aren’t a lot of flattering adjectives that can be applied to the so-called Standard Model. Built up bit by bit over the course of
