Back on May 21st of 2019, two giant black holes banged into each other, 7 billion light-years away from Earth.
Spacetime reacted by stretching, collapsing, jiggling, and producing gravitational waves that rippled across the cosmos.
Scientists here detected the disturbance using LIGO, a pair of identical, two-and-a-half-mile-long interferometers in Italy, and they’re calling it the biggest farthest, and “most energetic” black hole merger ever.
The resulting black hole is about 142-times more massive than the sun.
The signal only lasted a tenth of a second, but scientists were excited nonetheless.
It’s the biggest bang since the Big Bang that humanity has ever observed. It could offer clues as to why the Universe looks the way it does.”
