I saw a YouTube video by some astronomy nerd seemingly specializing in simulation or special effects. Sorry I cannot recall the channel name.
He pointed out to the viewers that the amount of void in between stars that is visible is a bit misleading in all these super high res photos we see of our universe.
The video ended with some special effects/simulations of the night sky as seen from the South Pole. If the light pollution was literally zero, and you had eyes (or a camera) that could somehow see _all_ stars regardless of how far away they are, the night sky would basically look like a still picture of the color noise on an old analog TV. Hardly any black void anywhere, it’s just all stars. It was mind-boggling (and I hope true, not a scam video).
- consp 2y agoThe CMB is uniform, so if you go back far enough that is true (and apply a blueshift). Amospheric disturbances would smear out a lot of it though, so no points like in analogue thermal noise.
