I have a love/this makes me want to vomit relationship with the vastness of the universe.
Unsure what side this recording leaves me on.
Just eat the fairy cake. That'll restore your perspective.
I thought it would be the sound of Johnson explaining himself. No one can escape his bumbling and bluffing.
It does sound a bit ghostly.

Started out with nothing. Still have most of it left.
Sounds like the Motorway from the bedroom of a Premier Inn!
This is Johnson in any scenario, you’re the one pinning it to politics.
I meant in any sphere, even his pre-politcal career; and was referring to how he seems to be disappearing up his own posterior, and unable to escape from it, much like nothing, including light, can escape from a black hole.
NASA explained that the soundwaves were resynthesised into human hearing range by "scaling them upward by 57 and 58 octaves above their true pitch" but were not replayed using violins or other instruments.
Thanks verv. I was lucky enough to study Astronomy and Physics to degree level at UCL. Cosmology and Quantum Mechanics where my specialist subjects and stuff like this is right up my street. Just keep things in perspective.

Can someone explain how this is even possible to know/record if there are no sound waves in space? This is beyond my elementary knowledge!
My understanding of the theory is that plasma falling into a black hole in a spiral path induces strong magnetic fields that cause two jets of matter to be ejected from the poles of the rotation. These jets can be observed to form two pressure bubbles which cause a ripple in the gas that surrounds the black hole. Although the gas is quite diffuse and the particles have to travel a long way between collisions (hence the very low frequency of the sound wave, and it is a sound wave) when they do collide, the high energies mean that the particles emit X-rays. Observers can track these X-rays to map the ripples and work out its frequency. It’s then just a case of multiplying that frequency by a number suitable to bring it into human hearing range, some 57 octaves apparently, and posting the audio on Twitter. The fact that you can listen to a black hole is not really the interesting part though, at least not to me. The mechanism behind these gas jets is not fully understood and the gas surrounding a black hole is a lot hotter than you might expect. It is thought these sound wave might actually be heating things up which might account for the heat difference from expectations. So what this discovery really does is give astronomers another signal to use to try and figure out what’s actually happening near a black hole. And that is a really neat technique to have found.
Amazing and simple explanation that even I could understand, thank you. We need that more often.
This does sound exciting and I'm always impressed at the stuff some crazy scientists/astronomers etc are always working on
Very ethereal and creepy.
