You wanna hear my evidence-free cosmic structure theory? Of course you do.

If you shine a laser through a mass of soap bubbles it will unsurprisingly split into lots of smaller beams due to a mix of refraction and reflection. I have long held the suspicion that there's an isomorphism between gravitational and surface tension structures, that the multiplicity and distance of galaxies may be somewhat illusory, and that many of them are translated/rotated reflections of nearer ones. Laugh now, perhaps gasp in wonder later.

Sounds like domain walls.

This concept is a bit too advanced for me (or the page is too minimal to easily understand), but it sounds fascinating. I'll read up more on it, thanks.

Fair critique! I tried to find a more accessible Wikipedia article but they all look like this...

Simply put, it's a topological defect or discontinuity, but that makes it sounds worse than it really is. I find it easiest to visualize with magnets. They want to align with their neighbors, so in general you get big blocks (domains) where all particles are aligned. What happens at the border when blocks with different alignments meet? We call that a domain wall. That's literally all it is!

You can find domains walls in magnets, metallic crystal grain structures, liquid crystals, pretty much anything that wants to self-align. One issue: gravity doesn't particularly want to self-align. Or does it?

I've only got a surface understanding of this stuff myself. Best of luck in your research!
