The sound of a black hole
We may not hear a voice in space, but that does not mean it does not exist. In 2003, astronomers discovered something truly astonishing: talking about acoustic waves propagating in a gas pile near a supermassive black hole that is 250 million light-years away.
However, it is usually impossible to hear them. The waves emanating from the supermassive black hole at the center of the Perseus galaxy cluster contain the lowest sound note ever detected by humans. This is well below the human hearing capacity.
The new sonification (converting data to sound) not only converted it, but also upgraded it to 57 and 58 octaves. So we can listen to it now. This is the first time such sound waves have been heard by us.
The sound is 288 quadrillion times higher than the original frequency. You can listen to it at the link below:
However, all this is not just for listening and satisfying curiosity. The sound waves propagating in a cluster environment are an interesting study because they propagate in the form of energy. Because temperature is involved in regulating star formation, sound waves may play a crucial role in the evolution of galaxy clusters over a long period of time.
Converting similar data into sound could be a new way of understanding cosmic phenomena, and the method has scientific value. Sometimes a transformation of a database can reveal hidden details, allowing for more complex discoveries about the mysterious and vast world around us.
