This is a transliteration of the latest image of a supermassive black hole called Sagittarius A (SGR a ) in the center of the Milky Way galaxy from the event horizon telescope (EHT) - that is, translated into sound It is reported that the scanning sound wave starts at 12 o'clock and then sweeps clockwise. The change in volume represents the brightness difference observed by eht around the event horizon of Sgr A *.
Matter that is closer to the black hole and therefore moves faster corresponds to a higher sound frequency. This sound wave is specially processed so that the audience can hear the data of three-dimensional stereo. In this case, the sound seems to start directly in front and then move clockwise to one ear and then the other ear as the scanning progresses.
