        DOES A BLACK HOLE HAVE SOUND?

RECENTLY IN AUGUST 2022, NASA DISCOVERED THE SOUND OF A BLACK
HOLE. YES, YOU HEARD IT RIGHT.

BUT WE ALL KNOW THAT SPACE IS A VACUUM, THEN HOW COULD SOUND
TRAVEL THROUGH IT? WHERE THERE IS NO MEDIUM, THERE’S NO SOUND!

BUT THE GALAXIES WHICH HAS LOTS OF STUFF HAPPENING INSIDE THEM
LIKE FORMING OF STARS, THE DYING OF STARS, AND THE CLASHING OF TWO STARS. THESE HUGE EVENTS
DO PRODUCE PRESSURE WAVES IN THE SPACE.

THE BLACK HOLE AT THE CENTRE OF THE ‘PERSEUS GALAXY ‘CLUSTER
HAS GIVEN US THE FIRST SOUND OF ANY BLACK HOLE UNTIL NOW.

THE OFFICIAL LINK TO THE SOUND IS ATTACHED BELOW AT THE END
OF THE BLOG.

WITH THIS PRESSURE WHEN CONVERTED INTO AUDIBLE SOUND WAVES, WE CAN
HEAR THE SOUND IN THE SPACE. WELL, THIS WORK IS DONE BY NASA. THIS PROCESS IS
CALLED ‘SONIFICATION’. IT IS JUST LIKE TRANSLATING THE SOUND.

THE DATA FROMCHANDRA X-ray   OBSERVATORY
IS MERGED AND WITH LOTS OF COMPUTER WORK INVOLVED INTO IT, WE GET A SOUND OF
BLACK HOLE.

WITHOUT GOING INTO VERY DEEP INTO PHYSICS, I WOULD LIKE TO
TELL YOU THAT, THE ORIGINAL SOUND WE GET IS SO SMALL THAT HUMAN EARS ARE NOT
CAPABLE ENOUGH TO HEAR THAT SOUND, HENCE SCIENTIST HAS TO INCREASE THEIR OCTAVE TO 58 OCTAVE
ABOVE THEIR ACTUAL PITCH. THIS IS WHY WE CAN HEAR THIS SOUND COMING FROM THOUSAND
OF LIGHT YEARS AWAY FROM US.

IN CONCLUSION, IT IS SCARY HOW WE KEEP DISCOVERING SHOCKING THINGS EVERY DAY, BUT THE NASA ITSELF SAYS THAT THIS ISNT THE ACTUAL
SOUND BUT THE NASA’S SONIFICATION PROJECT, TRANSLATES  ASTRONOMICAL DATA INTO SOUND. WHICH HELPS
SCIENTISTS TO STUDY ABOUT OUR FUTURE MISSIONS.

WELL NOW  LET YOUR EARS
HEAR THE SOUND FROM A BLACK HOLE THAT YOU CAN NOT EVEN SEE WITH YOUR NAKED EYES.
