Have you ever wondered what a black hole would sound like if it were perceptible to a human ear? A NASA team has looked into the matter, as relayed by our colleagues from the New York Times.
It should be noted that the X-rays are regarding ten octaves too low to be audible, and that the X-rays are therefore transformed. Scientists at the Chandra X-ray Observatory have shared the songs of two black holes, the first in the Perseus galaxy, and the second in the Messier 87 galaxy.
And for this galaxy, it is not only necessary to sound the X-rays, but also the optical light captured by the Hubble Space Telescope and the radio waves detected by Atacama, in Chile. The result, very harmonious, is of a beauty difficult to believe.
