Less than two weeks after the gravitational wave detectors turned back on, they’ve already seen evidence of two pairs of colliding black holes. Continue reading Gravitational Wave Detectors Spot Two Potential Black Hole Collisions in a Week
The past few years have been incredible for physics discoveries. Scientists spotted the Higgs boson, a particle they’d been hunting for almost 50 years, in 2012, and gravitational waves, which were theorized 100 years ago, in 2016. This year, they’re slated to take a picture of a black hole. So, thought some theorists, why not combine all of the craziest physics ideas into one, a physics turducken? What if we, say, try to spot the dark matter radiating off of black holes through their gravitational waves?
For the second time this year, physicists at the Advanced Laser Interferometer Gravitational Waves Observatory (LIGO) are giddy with excitement. They’ve just confirmed the second detection of gravitational waves, ripples in the fabric of spacetime proposed by Albert Einstein a century ago. It seems we’ve officially entered the age of gravitational wave astronomy.
David Reitze, executive director of the LIGO Laboratory, took the podium at the National Press Building in Washington, DC, this morning, and said the words we’ve all been waiting on tenterhooks to hear: “We have discovered gravitational waves.” And a packed auditorium in Caltech’s Cahill building in Pasadena—where people had gathered to watch the live feed—erupted into wild applause.
Hey, remember when we told you about those rumors that physicists may have finally found gravitational waves? It’s been pretty quiet since then, but yesterday fresh rumors surfaced that yes, the discovery is real. And we could have an official announcement by February 11.
