Breakthroughs are exciting; hoping it's true! But I understand nothing of this field What's the general consensus here, real or not?
A few comments on diamagnetism: The most strongly diamagnetic materials that aren't a superconductor are bismuth and pyrolytic carbon, a graphite-like material. Bismuth has a density of about 10g/cm^3, and a diamagnetic strength (X) of -16.6 x 10^-5. It won't levitate above a magnet because it's just too heavy. Pyrolytic carbon has a density of 2g/cm^3, and a diamagnetic strength of -40 x 10^-5. Thin sheets of this l…
I've seen some people talking about the LK-99 samples only having these properties locally due to internal structure or something like that, could that not explain the angle if one part of the sample had more "pockets" of material with these properties than another part?
HN is such a weird place. Every so often it adopts these communities of people obsessed with something, and lately it's whatever LK-99 is. I wish they'd just go make a subreddit.
The smartest people obsessing over LLMs and LK-99 is exactly what I want, personally. They're potentially truly revolutionary things.

But this is so much fun! Reddit isn’t fun, and the energy here is just lovely

That isn't simple. The sample needs to be shipped. You have to ensure it doesn't get damaged in shipment. If some lab has a an unknown evil intent they can destory the sample and claim it was shipping damage. They say they are willing to let other labs examine their sample. If nothing has happened in two months i'll get worried, but for now I don't expect any lab to have seen it
Obviously they wouldn't just slap it in a box and send it through FedEx. The authors would personally deliver it.
Why is it necessary for other labs to produce the material themselves to verify the claims? The original authors claim they produced some superconductive material, can't they simply offer their samples to other labs to verify?
* Potentially do it better/purer
* Get a few news articles, and a mention in a very high traffic Wikipedia page
* Again if they do it well, get 8 figures in funding pretty easily. While during any other day they might be fighting for $50,000 here and $100,000 there

Whatever it is? I mean it could change our relationship to energy in the next 10 to 20 years. If you don't get excited by this then I don't know.

The lab has a patent though which a lows for disclosure while also profiting from it. Thus I am not totally convinced of your claims.

Yeah, I think unless the authors are deliberatly misleading the public (which is of course a possibility, though not very likely I think) it is hard to imagine a scenario where all of this won't turn out to be highly interesting in one way or another (even if it might turn out to not be a superconductor)
