You may have always wondered what it sounds like in the center of the universe especially in the darkness of a Black Hole. Well, this week, NASA released real audio from a Black Hole in the Perseus galaxy cluster. NASA said, "Astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C." NASA described how a galaxy cluster actually has a ton of galaxies within it providing the means for those sound waves to travel. Take a listen......(it sounds like a big scary whale to me!)
