A ‘Lowest Note Ever’ Has Been Found By NASA, Indicating Vibrations In The Sound Near A Black Hole Located 250 Million Light Years Away

The United States space agency, NASA, recently made a captivating discovery as they recorded an eerie audio clip capturing mysterious sound waves emanating from a supermassive black hole positioned an astonishing 250 million light years away. 

This incredible phenomenon unraveled in the vicinity of the black hole housed within the central hub of the Perseus cluster of galaxies. 

To render these enigmatic acoustic waves perceptible to the human ear, scientists ingeniously transposed the frequencies upward by a remarkable 57 and 58 octaves.

The audio was released in 2022

The sound waves were extracted and rendered audible for the first time when the audio was released in 2022. Waves, or vibrations in sound, actually exist in space even though they may not be audible to humans. 

Astronomers made the startling discovery in 2003 that there were acoustic waves resonating through the immense plasma around the supermassive black hole in the Perseus galaxy cluster. This object is now well-known for its unsettling humming sound.

At their current pitch, they include the lowest note ever discovered by humans in the universe, which is well below the range of human hearing, making it challenging to hear them. 

To simulate the sound of these waves resonating over interstellar space, NASA recently sonified the waves, greatly increasing their amplitude.

The lowest note is a B-flat

According to the article, the lowest note was discovered in 2003 and is a B-flat, which is more than 57 octaves below middle C. Its frequency at that level is 10 million years. The lowest note that is audible to humans has a frequency of one-twentieth of a second, it should be emphasized. 

Following their radical extraction from the supermassive black hole, these acoustic waves were emitted from the core in an anticlockwise manner. 

This was done in order to increase their pitches to 144 quadrillion and 288 quadrillion times higher than their initial frequency, making them audible from all directions around the supermassive black hole.

The outcome of this wave was unsettling, as were a few other waves captured from space. The ‘intracluster medium’, a tenuous mixture of gas and plasma that floats between galaxies within clusters, is significantly hotter and denser than the intergalactic medium outside of it. 

Since temperature influences star formation, sound waves may be essential to the long-term evolution of galaxy clusters.
