I’m going to entertain this literally because it’s fun: so we need to zoom out enough to find those big galaxy surrounding atoms which are actually universes, or conversely to zoom in more to find galaxies and a universe within atoms. But it seems that there’s either missing understanding how to cross that zoom in/out threshold or it’s impossible by the laws of physics to zoom so far to make a full circle, like it’s forbidden for the snake to bite its tail. I imagine people have discussed this stuff a lot, and came up with better analogies and more nuanced models
