Scientists Have Detected Gravitational Waves Again
Computer simulation of two black holes merging into one
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. The discovery was announced this afternoon at a meeting of the American Astronomical Society in San Diego, CA, and has been accepted for publication in Physical Review Letters.
