Ten years after the historic discovery of gravitational waves, and having spotted hundreds more of these space-time swells since then, physicists say they are only just getting started. On 14 ...
On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...
Gravitational waves, tiny ripples in spacetime caused by cosmic collisions like merging black holes, are almost impossibly faint. Detecting them requires LIGO (Laser Interferometer Gravitational-Wave ...
