So what is going on here? Are these sounds from around the Stranger Pugs Shirt also I will do this black hole as they are pulled in or are affected by gravity but manage to escape? I mean they could be recording a dogs fart at lower frequency and slowed down and none of us would know the difference. Still cool though Is it truly a the sound if light cant escape how can a sound wave. If it’s the waves generated from the edge or event part then it’s no really what it sounds like. Technically its silent right? fyi, sound cannot travel through a vacuum. By definition it is a pressure wave through matter. What you are hearing is an x-ray signal (high frequency electromagnetic wave aka non-visible light) transcoded into an audible sound.
