It is fun to read these things, and of course discussion is a good thing, but I do hope that blogs and comment sections do not end up serving any formal role in the scientific literature.

There are several reasons for this: a blog's visibility is low compared to a preprint server (in the scientific community at least), the contents of the blog probably won't be as well-preserved, and there is a tendency to be more casual with the arguments.

Why is that even a concern for you here? This is clearly written for laypeople.

It may be just text, but the points being made are technical, and the blog's author is an expert.

The author of the paper is now in a position where they feel like they have to defend themselves publicly, and I don't think this is the forum for a scientific defense (for the three reasons I listed above).

Negative matter is created spontaneously everywhere, according the article in theconversation.com. Why then can't we collect it, isolate it, and poke and prod it? Because the particles are too small and interact too weakly?

> the particles are too small

That's not a good way to talk about these things. Usually it's the really small stuff that is very strongly interacting - see quarks.

> and interact too weakly

That's better.

Not every piece of discussion in science is formal and rigorous. Einstein didn't communicate his ideas exclusively through peer-reviewed papers. There is a time and place for informal talk, and this is it.

Why not? It all depends on the qualification of the people writing blog posts and comments. Remember that some 300 years ago a lot of scientific results existed in epistolary form only, and that first journals that looked like today's thing (like the Bulletin of the Royal Society) were basically compilations of letters sent by astronomers, naturalists etc and reactions of their peers sent as follow-up letters.

Naturally, this doesn't mean that anybody and their dog should have a voice in discussing matters like cosmology if they actually have no clue about it.
