I severly doubt that it is an actual room temperature superconductor, but would love to hear the opinions of more well informed people on that topic.

Wasn't there some recent excitement about some hydrogen sulfide superconductor thing? But the pressure required was wild/not-useful-for-use or something like that?

If this were true, I would’ve expected to see it on the front page of the New York Times, not hiding in a scientific journal. Color me skeptical, with a hint of optimism.

AFAICT this has not yet been published in a scientific journal, and has not passed peer review of any sort. Having said that, there's been at least one story on HN this past week where researchers were chastised for going to the press before properly vetting their results.

Almost all research are published in scientific journal. News outlets then pick some to report deepening on many factors from breakthrough development to just pure chance. So this is not something strange.

Actually the opposite is the strange. I would be skeptical of any group the report something in media before publishing the results in a journal (or arxiv like this case).

This is not to say anything about this particular paper. I still have to read it eventually.

I share your doubt, but on the other hand I wonder why? Could you tell how a breaking message of this magnitude should be decorated to make all doubts go away?

It might be broken in an unreviewed preprint like this.

But there will likely be very many bogus preprints for each true extraordinary finding.

Therefore most things showing up like this are untrue.

big if true. far from a chemistry expert here, but synthesis looks basically trivial (if you consider 10e-5 torr vacuum to be trivial), and the materials are readily available. hell, from the instructions alone i could probably make it at home. i mean the search space is unfathomably large, so i suppose it’s possible that something like this exists, but the paper quality itself doesn’t.. spark joy? :) i’ll maintain a…

If it's true, it'll also SPARC joy. And ITER etc

You have a lot of faith in the New York Times to know what’s important.

Earlier quoted context omitted.

127°C, so it is room temperature if you first set your room alight.

From my understanding it is superconductive up to that temp. So, superconductive at room temp and even further.

That makes me even more sceptical. In recent years confirmed discovery of superconducting materials have gone from working at best up to ~100K below room temperature to at best a few 10s of K below. To jump to a material that claims to exhibit superconductivity as far as >100K above room temperature, at ambient pressure too, is an extraordinary claim and so needs to be presented with extraordinary evidence.

Will they invite a wide range of experts to publicly test their material?

The instructions they provide in the paper seem fairly straightforward and reproducible, I'd expect that if this is in fact legit, there will be many attempts to replicate the result quite quickly.
