I am following this story closely as well. I'd love for some technological breakthrough to leap us into the future. Unfortunately with this one it seems to be mixed. Someone here on HN posted this thread yesterday by a guy who's actually in Seoul: https://nitter.net/sanxiyn/status/1685094029116297216 And from this account it doesn't exactly look like a professional outfit that made this. But I'm still holding my breath until other labs attempt to replicate.

Yeah, that guy was linked in the Twitter list above.

The papers on arXiv are "crap" because they weren't ready for publication... the actual team's paper has been submitted for peer review to a respected journal and is being looked at/corrected/tested.

What got published was leaked, hence the poor quality work.

Check the twitter list for more info.

Ah, I see, sorry for not checking ahead. Unfortunately it seems the link is blocked behind the auth wall and I would rather not make a new social media account, but that's good to hear that it's more legitimate than that thread would suggest, thanks for the info.

Not sure how to take that "weren't ready for publication" thing. That kind of wording is not rare in fabrication cases.

Which "respected journal" is it?

There is definitely a mix of evidence from the people side of the equation. Rank amateurism mixed with well credentialed researchers. Check out this vid from EEVBlog highlighting one of the worst “amateur hour” parts: https://m.youtube.com/watch?v=QHPFphlzwdQ (tldr is that the main website shows a vid waving a magnet in front of a copper disk coated in their new material. The copper plate moves around because of Lenz’s law! Nothing to do with superconducting)

Meanwhile, the very well credentialed HyunTak clearly believes it’s real, but he was parachuted in late in the development.

Personally, I think we will just have to wait the week to see if this is real.

I kinda wonder if that particular vid was posted by YH Kwon... it would have been posted while he was still involved in the group.

It's very obviously not a U-235 disc by the color, unless the LK-99 film changes that somehow? Plus, if it's supposed to be pure U-235, why use that? Weapons grade enriched fissile uranium used in demonstration of properties of a thermally deposited film?

That video makes no sense at all.
