If you follow the link from this article to the preprint, you'll find some explanations, references to other papers, as well as enough terminology to do some Googling.

Have fun! It's quite interesting.

Yeah, read the site guidelines, yo.

I actually read the article, as you can see by the other comments I've made, and found none of that, but please feel free to correct me and cite here the portions of the paper where that is mentioned.

And sure, I could specialize in cosmology and find out the reasons on my own, but also, the burden of proof on that argument is not on me.

Introduction, paragraph 2:

>The multiple discoveries of LSSs made throughout the past few decades are well known to challenge our understanding of the Standard Cosmological Model (ΛCDM) [2, 8–12], in particular due to a possible violation of a fundamental assumption, the Cosmological Principle (CP), which states that our Universe is both homogeneous and isotropic on large scales

That gives you a couple papers and a few terms that you can get started with. Unless your goal is to argue, instead of learn, which it seems like it might be.

Context, as it seems to have been missed:

>For reasons*, there's a soft limit on the scale that you'd expect structures** to scale to.

The content you cited acknowledges the premise of the Cosmological Principle, but it does not say anything about what these "reasons" could be.

So, nope, that's not an adequate argument.

Again, I could waste my time on a PhD in Cosmology to come back and actually make a good argument for why homogeneity in structure is favored at large cosmological scales ... but why should I? I didn't bring that particular argument into the conversation [1].

>So, nope, that's not an adequate argument.

I'm not trying to argue, lol. You're asking for more information but in such a weirdly aggressive way.

The reason there is a soft limit (in our current theories) is because of the cosmological principle

Big lol at the wiki linking of burden of proof. Not every conversation is an argument, holy.

As much as I love HN, this type of aggressiveness and desire to converse as if defending a dissertation can get bloody exhausting.

My "Have fun!" was genuine, I had a lot of fun learning about this stuff despite not pursuing a PhD in cosmology. Anton Petrov covers this specific topic in a few videos, as well as other large structures, and it's truly fascinating.

The rest was probably a bit uncalled for, you're right. I was immediately put on edge by "Yeah, read the site guidelines, yo." (which, uhh, not sure how that is focused on moving the conversation forward but lets leave it at we were both touchy!)
