Sound waves from the black hole are '288 quadrillion times higher than their original frequency.'
Any Xenomorph-fearing 'Alien' fan will tell you that sound doesn't exist in space. The thing is, that's not completely true.of a black hole showing that space does make a lot of noise, depending on where you look, and how you process it.
The clip presents the sounds of a massive black hole located more than 200 million light-years away from Earth in the Perseus galaxy cluster.The Perseus galaxy cluster is an 11 million-light-year-wide grouping of galaxies enveloped in hot gas. Those clouds of hot gas are the key to the sound waves you can hear in the clip shared by NASA . Decades ago, scientists discovered that pressure waves emanate from Perseus' interior.
Sounds on Earth occur when sound waves vibrate atoms and molecules in the air. In space, things are somewhat different. Space is a vacuum, meaning vibrations don't have any air to vibrate and make noise in. Crucially though, that doesn't mean the vibrations aren't there. That's the principle the NASA scientists put into effect for their sound clip.
The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole!
