When two black holes collide in space
Will we hear sound?
Einstein said yes, and today we know he was right
What does gravity sound like after two billion years – whooOOP
What do scientists say when they discover gravitational waves – whoOOPeee
Black holes crashing together in the night sky do not happened every day. That said, in the universe there is no night, no day and no years to count the time that passes. But we now know that the sound is whooOOP, kind of like a G string followed by an A string on an electric guitar.
Listen to John Mayer sing Gravity.
