In 2003, NASA’s Chandra X-ray Observatory detected a sound wave from the Perseus cluster, which is more than 200 million light-years away from Earth. The frequency is too small to be heard by humans. NASA has recently “auditified” it. The full version of the voice is expected to be exhibited at this year’s NASA Black Hole Week (May 2-6).
NASA hears “black hole” sound waves and confirms that there is a medium in the universe that can transmit sound waves
The acoustic data obtained by NASA this time from the Perseus galaxy cluster are actually ripples in the gas, and the reason why such a signal can be received this time is due to the large amount of gas in the countless galaxies in these galaxy clusters, which provides gas. A medium for sound waves to pass through.
From the perspective of someone who has studied music, this sound wave is located about 57 8 degrees lower than the central C, which is about B flat major, so it is inaudible to humans. In the process of converting sound waves into sounds audible to humans, astronomers use sound effects to synthesize the sound waves emitted from the black holes in the galaxy clusters, which are a bit like the rumbling sound of thunder and the groans that appear in horror movies.
At present, the black hole sound of the Perseus galaxy cluster has been listed on YouTube’s “Data Sonification: Black Hole at the Center of the Perseus Galaxy Cluster (X-ray)”. NASA said that there is another well-known black hole Messier 87 or M87 sound wave recently. An auditory translation is underway, and scientists are rumored to have been tracking the black hole for over a decade, and Messier 87 first debuted as a project with the Event Horizon Telescope (EHT), which has even gained a high reputation.
