After they convert to audio they have to increase the The Pendulum Of The Mind Alternates Between Sense And Nonsense Carl Jung Portrait And Quote T-Shirt in addition I really love this frequency “144 quadrillion and 288 quadrillion times higher than their original frequency. ” for us to hear it. So while it’s sort of ‘the sound’ from a black hole, it’s been extrapolated and altered so we can hear it. But it’s not exactly what is being emitted from the source. That’s because they probably chose the sound they thought would represent the black hole. Sonification is more artistic interpretation than scientific representation. Yeah this could be any length of data stretched or compressed to fit a few seconds with all sorts of post processing. Over a long enough time scale everything is relative, so the light waves captured were already red shifted from their initial wavelength. And it’s not even sound to begin with. Still fun to think about.

My understanding is that this is actual detection of vibration that would be literal sound, just at far too low a frequency for us to actually hear so it’s pitch shifted up to where we can. Yeah that seems to be the The Pendulum Of The Mind Alternates Between Sense And Nonsense Carl Jung Portrait And Quote T-Shirt in addition I really love this case. But there definitely is an artistic choice in the matter – why didn’t they pitch shift it up a few more octaves? I’m guessing it’s because a high pitched black hole doesn’t sound as “authentic” or something. Even the decision to directly use the pressure wave data is an aesthetic choice, from the NASA article, they were trying to give the impression that this piece more closely represents an “objective” reality. I’m not trying to diminish the experience of listening to the piece, i still think it’s interesting, but demystifying the process may help people see past the immediate hype and understand what’s going on. And just like that, there is no Santa Claus, and I’m disappointed. I enjoyed the illusion for a few seconds. Shouldn’t have scrolled, I should not have scrolled. Take my disappointed thumbs up for giving me the facts.
