What is the sound of a black hole? NASA reveals this in this recording – Western France Evening Edition

space, silent? Not at all, says the US space agency NASA, which has rebroadcast the sound of a black hole coming from the Perseus galaxy on social networks, 250 million light-years away from our solar system.

We get a complete idea of ​​the space. We imagine it cold and terrifying but above all silent. Well, that last point, at least, is wrong! We know this thanks to the audio recording Published by the US space agency NASA. A recording was already broadcast in May 2022 but the Foundation just introduced it, on social networks. This annoying sound, due to its gravity and mineral power, comes from a black hole located in the center of the Perseus Galaxy, about 250 million light-years away from our solar system. What we hear is precisely the mass of gas gravitating around the black hole, rippling under its pressure. embarrassed.

Space is not silent

As NASA explains, the idea that all space is silent stems from the fact that most of it is empty space. Without matter, there is no possibility of sound propagation. He went, “A group of galaxies containing large amounts of gas enveloping hundreds or even thousands of galaxies of which it is composed, and thus providing support for the propagation of sound waves”, explain NASA in a statementtransmitted by the media vice.

The voice is heard thanks to the work of NASA specialists

This sound comes from data recorded by the Chandra Space Telescope. NASA tricked us into hearing it. Because this data was inaudible to the human ear … so the space agency’s specialists brought it back to its “us” level, by increasing its original frequency.

Then they combined these sound waves with other information collected by the spacecraft, in particular light… “It wasn’t intentionally annoying,” Reassures NASA in a message posted on the social network Twitter. The agency also explains it “One of the motivations for creating such sonication of data is the desire to share the science with more people.”
