You Need To Hear What Colossal Black Holes Actually Sound Like

Have you ever wondered what a black hole sounds like? Technically, in the vacuum of space, there is no sound, but Janna Levin and the folks at LIGO have found a way for you to experience the strange phenomena of two black holes colliding.

Black Holes Colliding

In the video, Levin, a professor of physics and astronomy at Columbia University and the author of Black Hole Blues, gives some facts about space, black holes, and the “sound” that is created by the two massive black holes colliding in space. The singularities in question are 30 times the mass of the sun and are 1.3 billion light years away. The video goes on to explain that these holes cannot be witnessed by the eyes, but the change in space around them signifies their existence. Levin explains that since there is no sound in space, the sounds we are actually hearing are gravitational waves, which is the ringing of the shape of space itself. The collision that LIGO was able to capture created what she describes as a loud chirp. “You could say black holes are playing drums out there. Space-time is the drum, and black holes are the mallets,” she says. The sound is created by recording the actual shape of the ringing drum and creating a sound to match the wavelengths.
