Black holes are not terrifying only by their appearance and functions, although it’s close to impossible to see one directly since these cosmic monsters don’t even emit any light. NASA has now made it possible actually to hear how black holes sound. While it’s not something entirely new, we now have a chance to listen to the spooky echoes of a black hole from V404 Cygni, according to DigitalTrends.
V404 Cygni is a microquasar and a binary system located in the constellation of Cygnus. The Cygnus Loop is located 1470 light-years away from Earth. Data provided by NASA’s Chandra X-ray Observatory and the Neil Gehrels Swift Observatory was used to make the sonification possible. The Pan-STARRS telescope from Hawaii has also provided data from the optical wavelength.
Transforming X-ray light echoes into sound
The new sonification in question transforms x-ray light echoes into sound to present us with how a black hole can sound. The sound is actually coming from background stars. Feel free to listen:
Not only that black holes don’t emit any light; they absorb light from stars or galaxies that get too close, which is strong proof of the unfathomable and incredibly powerful gravity of these cosmic monsters.
As for the black hole from V404 Cygni, it absorbs material from a star located nearby and leads to the creation of intense bursts of energy. X-ray radiation is ejected from the black hole and interacts with gas and dust.
Just a few days ago, we shared the news about scientists from Bulgaria proposing an incredible theory: some black holes might actually be wormholes. The theory might not be far from the truth, although nobody hasn’t proven the existence of wormholes just yet. By definition, wormholes are shortcuts in spacetime, which means that they could allow us to travel to extremely remote regions of space in an instant.
