In 2002, astronomers using NASA's Chandra X ray Observatory discovered something unbelievable in the Perseus galaxy cluster. A supermassive black hole located 240 million light years away was sending out acoustic waves through the hot gas surrounding it.
These sound waves translate to a specific musical note: a B flat. However, humans cannot hear it naturally because the pitch is 57 octaves below middle C. It is a sound wave millions of billion times lower than the limits of human hearing.
To let human ears experience it, NASA scientists resynthesized the data in 2022. They scaled the light and pressure waves up by 57 and 58 octaves so the cosmos could finally be heard. Space is not completely silent when supermassive black holes are involved.
What does it feel like to know the universe is constantly playing a deep musical note?
