There's something kinda poetic (and maybe even logical) about the idea that what we perceive as scattered galaxies and physics is actually just the internal processes of something far bigger than we can comprehend.
Poetic, or maybe Lovecraftian. A lot of "cosmic horror" has the trope of vastnesses too big to comprehend, where even trying to think about it (or in some cases merely learning of the possibility) causes you to go mad.
It's like the deeper we peer into reality, the more it starts to look like fiction we were never meant to read.
