How NASA Captured Sound Of Black Hole (Black Hole Remix)

Recently, NASA discovered the sound of black hole. A sound about the which we cannot ever imagined. Because we cannot see the black hole with our naked eye. But why? A black hole is a place in space through which even light cannot pass. It has a strong gravitational pull that can absorb anything in it. Our scientists made the discovery of black hole and since then they were fascinated by its doings but they never heard how it sounds or did not even know if it has a sound of its own. Recently, NASA got something said to be the sound of black hole.

On 22 aug,2022 NASA tweet about sound of black hole. But original sound we cannot hear so NASA increased 144 quadrillion times the original sound so we humas can hear. So now you think how is original sound and how they detect this? NASA increased 57 octaves of original sound. We can hear its amplified of original version. NASA's CHANDRA X RAY OBSERVATORY scan universe from all sides. It observed that PERSEUS GALAXY is generating pressure waves. Pressure waves is generally a sound. Scientists observed that this galaxy's sound waves are generally created by black hole. 

Black hole's pressure waves are so high that it creates repulse on hot gases formed by clusters. But this cluster is 240 billion light years away, so how NASA detect this sound. Can they have this type of technology, well no. The process is called sonification, means extraction of sound from images. But how? It is not first time by NASA, earlier NASA use this technique for infrared, x ray or optical images to create sounds. The objects in the images and this Object's brightness can be converted into pitch and then like it is beautifully scanned whole image like music sheet. 

But in black hole the case is slightly twisted they cannot pitch brightness but pitch density waves and scan clockwise instead of left to right.  But if you have question that how sound is present in space because there is no medium in space. That is pressure waves because of gas and dust and this galaxy cluster is wide by many light years so this pressure waves only created by this. But what if we have to detect original sound we have to make sensitive detectors and send to this clusters and detected sound should be amplified many times. But it has left many questions that if we made this technology then how is really sound of black hole and how many more different sounds are present in this universe.

I RECOMMEND YOU HEAR THE SOUND OF BLACK HOLE
