Einstein's theory confirmed again: Scientists detect gravitational waves for second time

They’ve done it again. Scientists using the Laser Interferometer Gravitational-Wave Observatory have detected a second collision between two black holes that sent telltale ripples through the cosmos.

The discovery, described in a paper accepted to Physical Review Letters and presented this week at the American Astronomical Society’s 228th meeting in San Diego, confirms that LIGO’s initial groundbreaking discovery of gravitational waves was no fluke. It also draws the first brushstrokes that begin to fill in our understanding of these invisible denizens of the universe.

“It really feels like we are maturing as astronomers,” said
