Around 1.3 billion years ago, in a far-flung corner of the universe, two black holes — the densest, most destructive forces known to nature — collided with each other.
A hundred years ago, Albert Einstein predicted that such a massive collision would distort the very fabric of space and time itself. Like a stone cast into a pond, the cataclysmic disturbance would ripple outward at the speed of light, filling the ocean of the universe with gravitational waves. Einstein, however, never thought it would be possible to detect such waves.
In a massive achievement of human ingenuity and patience, scientists announced in 2016 that they had detected these waves as they slid through the Earth. (Since then, they’ve detected them three more times.) And Tuesday, their effort to record gravitational waves for the first time — a decades-long collaboration involving thousands of scientists around the globe — has been awarded the Nobel Prize in physics.
A Nobel can only go to a maximum of three laureates, however, and so this one went to physicists Rainer Weiss, Kip Thorne, and Barry Barish. They pioneered LIGO, or the Laser Interferometer Gravitational-Wave Observatory, the scientific project that made gravitational wave detection possible.
