Neil deGrasse Tyson - James Webb Telescope Just Detected 900 trillion Stars DISAPPEARING

What noise does a black hole make? People who have listened to an audio sample that NASA uploaded on Twitter have described it as "scary" and "ethereally wonderful."
The Perseus galaxy cluster, which is around 240 million light-years from Earth, contains a black hole at its centre. The American space agency tweeted what it described as a remixed sonification of this object. According to NASA, the sound waves discovered there over two decades ago were "extracted and made audible" this year.
People were astounded that anything, much less what sounds like a creepy, guttural groan, could exit a black hole after watching the 34-second film, which erupted on social media.
The notion that there is no sound in space, however, is false, according to the organisation. A galaxy cluster, on the other hand, "has abundant amounts of gas that encircle the hundreds or even thousands of galaxies inside it, providing a channel for the sound waves to traverse," it added. Whereas most of space is a vacuum with no medium for sound waves to pass through.
The video, which NASA referred to as a "Black Hole Remix," was initially made available in early May to coincide with Black Hole Week. However, a tweet from the NASA exoplanets team on Sunday really got people's attention, since the video had been seen more than 13 million times.
After 53 hours of observation, scientists with NASA's Chandra X-Ray Observatory "found that pressure waves pushed out by the black hole generated ripples in the heated gas of the cluster that could be translated into a note," which led to the discovery of the sound waves in 2003.
The frequency of that note, however, was too low for humans to hear since it was akin to a B-flat, which is around 57 octaves below the middle C note of a piano, according to NASA. So, Chandra astronomers altered the audio and raised the frequency by 57 and 58 octaves. The frequencies are being heard 144 quadrillion and 288 quadrillion times higher than they were originally, according to NASA.
The sonification project's chief investigator, Kimberly Arcand, remarked that she leaped up in delight when she first heard the sound in late 2021, which she compared to "a lovely Hans Zimmer soundtrack with the melancholy level set at extremely high."
According to Chandra's visualisation scientist and emerging technologies lead, "It was such a fantastic picture of what was in my imagination." She said that it also served as a "tipping point" for the sonification initiative as a whole since it "truly aroused people's imaginations."
It also suggests potential future study areas. It is "extremely intriguing" to think that there are supermassive black holes scattered around the cosmos that are "belching forth wonderful tunes," continued Arcand.
A Deep Voice from Deep Space
The sound in NASA's remix, according to experts, isn't precisely what you'd hear if you were miraculously standing next to a black hole. According to Michael Smith, an astronomy professor at the University of Kent in England, "those sound waves" couldn't be heard by humans since their ears aren't "sensitive enough to be able to pick them up." But if we magnified it, we would be able to hear them since they are present and are of the proper frequency, Smith added. He compared it to a radio, saying that when the sound is turned up, the level is higher and you can hear it.
