Nasa Publishes Terrifying Sound Of A Black Hole

NASA has shared a 34-second clip of the Perseus galaxy cluster, which is about 240 million light-years from Earth. Scientists say the black hole emits pressure waves that cause ripples in the hot gas, which can be translated into a note. To be clear though, the real note is something that people can’t hear. It is about 57 octaves below middle C. NASA says they changed the note so we can hear it by amplifying it and mixing it with other data they have on black holes. Scary sound will be perfect addition to your Halloween playlist. Copyright 2022 CNN Newsource. All rights reserved.
