Rob Sheldon on Physics Nobel for gravitational waves: Another PC moment in science?
From Megan Gannon at LiveScience: BERLIN—As expected by many, the 2017 Nobel Prize for physics went to three scientists who helped detect gravitational waves, ripples in space-time predicted by Einstein. “This year’s prize is about a discovery that shook the world,” said physicist Thors Hans Hansson, announcing the winners from Stockholm. … On Sept. 14, 2015, LIGO’s two extremely sensitive instruments in Washington state and Louisiana simultaneously observed a faint gravitational-wave signal. The ripples in space-time came from a pair of two massive black holes that spiraled into each other 1.3 billion years ago. More. Our physics color commentator Rob Sheldon is, however, left with more questions than answers: The Nobel was awarded because the waves were finally seen–after 10 Read More ›
