Thinking aloud about a hollow thought

Albert Einstein predicted the existence of gravitational waves 100 years ago.

In September 2015, scientists at the Laser Interferometer Gravitational-Wave Observatory in the northwestern US state of Washington detected the gravitational waves generated by the merger of two collapsed stars about 1.3 billion years ago. The journal Science reported the breakthrough, one of the greatest in physics and one that proves Einstein's theory of gravity and theory of relativity, on Feb 11. Black holes do exist.

Less than two weeks later, the Geneva-based European Organization for Nuclear Research, or CERN, took us from the theory of relativity to a "theory of reality", as scientists talked about "opening a door into an unknown and unexplored world".
