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.Advertisement
First, two black holes spiraled in towards each other, collided, and merged:
"Now that we have the ability to detect these systems, now that we know that binary black holes are there, we'll begin listening to the universe," Reitze said.
