Hear what a Black Hole sounds like thanks to NASA’s Sonifications remix

In space, no one can hear you scream, but that doesn’t stop space screaming back at you.

It’s a common misconception that there is no sound in space.

This is because most of space is in a vacuum, meaning sound cannot travel, but it doesn’t stop interstellar objects and cosmic bodies from producing noise.

The results can be eerie, haunting, beautiful and even a little terrifying.

Take Saturn for example, one of our solar systems most mesmerising planets for its epic rings and enormous size.

However, it also produces one of the most bone chilling sounds imaginable, coming straight out of the fevered imaginings of Event Horizon or Alien.

Yet, Black Holes have been one of the most mysterious objects in space for decades, with the first picture of one only betaking in 2019.

Now NASA has released the sound of these scary-cool goliaths of space and its just as unsettling as you’d expect from something that literally devours light itself.

What is a Black Hole?

A Black Hole is essentially a mass of gravitational pull that even has the energy to suck in light itself.

As NASA states: “A Black Hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space.

“This can happen when a star is dying. Because no light can get out, people can't see Black Holes. They are invisible.

“Space telescopes with special tools can help find Black Holes. The special tools can see how stars that are very close to Black Holes act differently than other stars.”

What does a Black Hole sound like?

NASA has understood the sound Black Holes make since 2003 – specially the one at the centre of the Perseus galaxy cluster.

As NASA explained: “Astronomers discovered that pressure waves sent out by the Black Hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C.”

The space agency has used new sonification (the translation of astronomical data into sound) to release their new remix of a Black Hole’s noise so that we can hear it.

NASA states: “The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch.

“Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency. (A quadrillion is 1,000,000,000,000,000).”

What is beyond a Black Hole’s event horizon?

An event horizon is the area beyond a Black Hole’s escape velocity – the speed needed to escape the cosmic vortex.

Therefore, the event horizon is the threshold around the Black Hole where the escape velocity surpasses the sleep of light.

Long story short, you wouldn’t want to be near it.

The truth is, no one knows what is beyond it, but it hasn’t stopped scientists from piecing together the evidence.

As stated in Albert Einstein’s theory of special relativity, nothing can travel faster than the speed of light, so an event horizon is the point from which nothing can return.

Speaking to Space.com, Avi Loeb, chair of astronomy at Harvard University, said: “The event horizon is the ultimate prison wall — one can get in but never get out.

"The event horizon protects us from the unknown physics near a singularity.”
