Στο διάστημα, κανείς δεν μπορεί να σας ακούσει όταν φωνάζετε – εκτός κι αν είστε κάποια τεράστια μαύρη τρύπα. Η NASA το απέδειξε την Κυριακή, μοιράζοντας ένα βίντεο που περιέχει τον ήχο μιας μαύρης τρύπας.
And if you're wondering how sound travels in the vacuum of space, NASA reports:
“The misconception that there is no sound in space comes because most of space is a vacuum, which provides no way for sound waves to travel. A cluster of galaxies has so much gas that we were able to capture the sound. Here it is amplified and mixed with other data. Let's listen to a black hole," NASA's Twitter account said.
The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole! pic.twitter.com/RobcZs7F9e— NASA Exoplanets (@NASAExoplanets) August 21
The galaxy cluster you're "hearing" is Perseus, data from NASA's Chandra X-ray Observatory and recording released in May for NASA's Black Hole Week.
As NASA explained it at the time, "astronomers discovered that the waves emitted by the black hole caused ripples in the hot gas of the galaxy cluster that could be translated into notes."
To us, it sounds like the beginning of some really awful dubstep.
