This black hole collision produced the first gravitational waves ever heard
Einstein was right. Ripples through the fabric of spacetime called gravitational waves do exist.
Physicists just confirmed the first detection in a signal that came from a cataclysmic collision between two black holes that happened 1.3 billion years ago. Those ripples have just finally made their way to Earth.
The team of scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) created a simulation from the data they collected to show what the powerful event might have looked like.First, two black holes spiraled in towards each other, collided, and merged:
The collision and merger between the two incredibly dense objects created a "violent storm in the fabric of spacetime," Reitze said. Ripples of gravitational waves spilled out:
"The Earth is jiggling like jello," Reitze said during the press conference as he explained the simulation. In reality that jiggling is barely perceptible.
