The internet is boiling after NASA shared an audio clip of a black hole - NRK Nordland

The internet is boiling after NASA shared an audio clip of a black hole – NRK Nordland

Is it a myth that there is no sound in space?

An audio clip shared by NASA recently Twitter may indicate that.

The clip is 34 seconds long and has been watched by 15 million.

On TikTok, people are going crazy with excitement. and wonder.

– Scary!, Read many comments.

black hole sound

So what exactly did NASA share?

The special thing is that the sound source is one Black hole.

Yes, you read that correctly.

The black hole is located in the center of the Perseus group of galaxies.

The reason the sound can come out of it is because the researchers discovered something special:

The black hole emits pressure waves.

These create ripples in the hot gas that can translate to… tone, ring.

The galaxy cluster contains so many gases that we were able to pick up a real sound, writes NASA Twitter.

What does the sound remind you of?

A lot of editing had to be done

The musical note is about 57 octaves below the middle C on the piano, which corresponds to B ♭.

So NASA “remixed” the audio so that it’s audible to us humans.

– It is amplified and mixed with other data, so that you can hear a black hole, they write.

Composer Raymond Inoxen, originally from Mosjøen in Nordland, believes the researchers have made an interesting piece of “musical” work.

– It looks so horrible. Terrible sound! But it is wonderful at the same time.

Composer Raymond Inoxen could imagine using voice in a production.

Enoksen is himself the owner and lead composer of Dreamscores, which is one of the country’s largest music suppliers for television productions.

He used the piano as his main instrument, and could also consider using the soundtrack as a starting point for the production.

– I have to check the rights!

– What kind of?

– That’s exactly what I imagine could fit into horror or excitement. Or as a starting point for an expensive work in artistic music.

Watch the video: He thinks there’s one reason in particular the clip is getting people’s attention:

Scientist: Thrilling

Svein-Erik Hamran of Fauske in Nordland was central during the construction of the Norwegian “Rimfax” georadar on Mars.

He also finds this interesting.

– Yes, this was very interesting, says Hamran, who, in addition to searching for Mars, makes music in his spare time.

They see that there are differences in the density of gas around the galaxy and believe that it originates from a black hole. Then they measure this and convert it into sound.

Does this break the myth that the room has no sound?

– It’s not a sound we would have heard if we were there. But it can be called a sound.

Away

NASA has long worked onClassified» scientific data and its a Our website Where you can hear voices from the universe.

The goal is to communicate scientific findings in simple language on social media, which is arguably successful.

NASA also participated in the “sonication” of the black hole in Perseus Earliers – As part of NASA’s “Black Hole Week”.

But it has now “exploded” online, after a message spread on Twitter on Sunday.

Several foreign media outlets spread on “Ice Talk” this week.

Among other things Washington Postwho noted that sound waves were already recognized nearly two decades ago – but now only “audible”.

At the same time, it is pointed out that one must not believe that this is the sound one would like to hear if one were close to a black hole with a voice recorder.

The audio you hear is edited up to 288 quadrillion times higher than its original frequency, according to NASA.

Critics have also pointed out that a number of assumptions must be made in the process of converting such data into sound (clusters of galaxies, after all, are far from us).
