Is there a way to search it for repeating patterns to catch any shortcuts the Simulation may have taken?
I understand Nebulae like the Eagle Nebula are fairly dynamic regions of space, so I find it interesting that we have photographs of the same region over a 27 years time span and at a glance, the structure of the Pillars of Creation appears virtually identical. I understand that 27 years is minuscule on the cosmic timescale, but what order of timescale would be necessary for the evolution of Pillars of Creation to be…
When I go outside I can barely see any stars, unlike my ancestors who saw a sky utterly filled with stars. Then I go on my computer and I can see more stars, with more details, than my ancestors even imagined. I can't decide if it's a worthwhile tradeoff.

Is it possible to visualize how a human eye would see Pillars of Creation in real time? This always confused me with Hubble’s colorized photos.
Scientists are unconcerned with that question. Your eye is nothing like the Hubble. Your eye isn't that useful for doing science. Hubble images are.
They're known for their strangely excited sounding monotones, although the only example I can think of is the not so scientific "burger king foot lettuce" video.

Handy Dandy Slider action between the two! https://esawebb.org/images/comparisons/weic2216/
Technically the comparison is not totally fair, that Hubble image was taken in visible light, while Webb's in infrared. Dust blocks visible light stronger, so background stars are effectively hidden from Hubble, but not from Webb. Here [1] you can see same field in visible and close infrared taken by Hubble. Webb of course shines in all the fine details and faint stars number. [1] https://cdn.spacetelescope.org/archi…

Webb observes "much further" into the IR [1]. 1. https://www.nasa.gov/sites/default/files/thumbnails/image/hu... (this image is from [2]) 2. https://www.nasa.gov/content/goddard/hubble-vs-webb-on-the-s...
Does this mean what Hubble sees is actually closer to what I'd see with my own eyes than Hubble, or Hubble's version is closer?
There is no way you could see this with your own eyes, there's no vantage point you can "stand on" to see the pillars - you'd either be too far away to see anything, or if you moved close enough so your eyes could actually focus on something, you'd be "inside" it, meaning you would see one star at most.
Imagine the civilizations that live between these pillars.
I compressed the full PNG via Guetzli (Google's high-quality jpg compressor) which took a couple of hours (now 15MB at 84% quality), so here it is: https://github.com/dvasdekis/images/raw/master/pillars.jpg and https://mega.nz/file/BTdWSb6b#NHK9lAtGMIr1UxabLiC174ZvJWo7KS... and https://www.mediafire.com/file/n0qjxogsp203z0w/pillars.jpg/f... The original crashed Windows when set as desktop background, but this one wor…
