Personally I think it's quite an interesting explanation for the paucity of elements 3,4, and 5, that they can only be formed by cosmic ray spallation. And, I'm not disinclined to examine various patch up theories of the early Big Bang and debate them. But, it took you so long to post a serious reply; instead you posted a slew of the ad hominem attacks.
I find somewhat interesting the contrast of what the HN community consider being worth to mention. Like between manned moon base plans and a cosmology related discovery we have the rumor of hiding Instagram likes.
Why HeH+? What about good ol' H2?
Apparently the universe was too hot for electrons to combine with atomic nuclei at first, so everything was a plasma.
As it cooled, He grabbed up electrons first, forming the first neutral atoms while H+ was still a plasma.
So there was a lot of He and H+ bouncing around at high temperature, allowing the first molecules to form as [He-H]+.
Yep. He has a higher ionization energy than H.
My question as well. I wonder if they're not counting H2 because it's only one element.

Hacker News is ostensibly focused on programmers building cool stuff.
A famous tech company doing something fairly minor will therefore compete with big news from a branch of natural science.
Many people are able to be interested in more than one thing.
