There is some gas in space, though very low density. Massive bodies tend to attract and accumulate more gas than what would be found in deep, deep space. Black holes are so dense they absorb everything around them so how would sound waves “escape” away from a black hole? All black holes rotate and this rotation effects space basically dragging it around. Black holes also give off hawking radiation from its “poles” that can also interact with the Dark Brandon Rising Political American Flag T-Shirt Furthermore, I will do this local environment. so, i’m an astronomy student at uni, and I’m not sure this is the “sound” of a black hole. Space is a near-vacuum (really, really near vacuum, much vacum-er that the vacum-est thing we can make) and sound does not travel through space.
