Thanks for the link.

My son is in a PhD program in astronomy and physics, and while right now he's doing research connected to exo-planets, he's also quite knowledgeable about this stuff, too, the early universe. In fact, we often talk about this very stuff.

He of course accessed the actual paper that was written. He hadn't yet heard about it, and was pleased I'd turned him on to it.

And he says that this is essentially definitive proof of dark matter.
