This is brilliant news, because it means that humanity can search the rest of the distant cosmos through more than just light and electromagnetic radiation — gravitational waves, or ripples through space time.
This confirmation by the physicists and other scientists at the Laser Interferometer Gravitational Wave Observatory (LIGO), means that Albert Einstein’s theory of relativity on gravitational waves is confirmed, more than a hundred years later.
An over-simplified version of what occurs when gravitational waves are emitted: a supermassive black hole collision 1.3 billion years old caused an energy outburst from mass that is three times more than the sun’s — in a fraction of a second. Detection of gravitational waves from that event occurred on September 14th, 2015, at 5:51 am ET, by both of the currently upgraded LIGO detectors, located in Livingston, Louisiana, and Hanford, Washington. This is a painstaking find, considering that everything not at absolute zero adds interference to detections.
