Music of the spheres

A black hole situated in the center of a galaxy amid a group of thousands of galaxies collectively called the Perseus Cluster (shown above) emits waves in a frequency equivalent to a B♭ 57 octaves below middle C, or one million, billion times lower than the lowest sound audible to the human ear. The Perseus black hole’s sound waves have a frequency of 10 million years.

This information, from an article published online by NASA, resonates with the philosophical concept often associated with Pythagoras and Johannes Kepler of Musica universalis or music of the spheres.

    “… one million, billion times lower than the lowest sound audible to the human ear”. Jag som precis kommit över att man inte alltid kommer kunna höra syrsor sjunga!
