I have been very cautious on any analysis on LK99 - especially my own. I have mentioned to many people that any potential application of this stuff comes with an 'if it is real'. That IF is doing a lot of heavy lifting and it has to be emphasized. I want this to be a thing, but it doesn't matter how much you want something to be true, it actually HAS to be true. A beautiful elegant idea can be crushed by a single ugl…

What happened to the original LK-99 samples that (allegedly) displayed SC properties? Were they just thrown in the dustbin, or what? I haven't seen that question answered or even asked anywhere, but I'm just a layman so maybe I'm not looking in the right places.

They were refusing to share them with anyone reputable until today. Today, they said they would share them, so hopefully this will all be over soon (but IMO it's already resolved).

If fake those researchers careers are over. Like, they'll have to go into programming or something. And they've also besmirched the good name of Korea, and their moms are going to beat the shit out of them for fucking up that bad. They've got a LOT to lose if this is fake, which is why I think it's most likely true. But hey, sometimes people just do crazy shit.

Impossible, wall street has some of the smartest scientists on the planet. They absolutely went through the research and determined it was a fake. Look at the AI boom, nasdaq rallied 40%. Superconductor would have had the same effect

Yea all those geniuses missed COVID completely though. And then the market overreacted in every way possible causing a crash then a rally that compared to nothing we have seen. Not sure the stock market tells us much of anything

Yes, but I take it like a rebuttal. They got the same effect that got everyone excited (half levitation) with a similar material that is ferromagnetic. Considering that there is a lot of unknowns and randomness regarding the synthesis of LK-99, and that the half levitation effect can be explained by ferromagnetism, to me, it sounds much more likely that the original LK-99 is a ferromagnet rather than a superconductor…

This is bad logic. Ferromagnetic explains half levitation but it doesn't explain full levitation. Superconductivity is sufficient to explain full levitation and half levitation. > Simply because ferromagnets are common Sure, metal ones are, but Are ceramic ferromagnets (without iron) common? That lone electron in an orbital is pretty important.

> Ferromagnetic explains half levitation but it doesn't explain full levitation

No one reputable has actually demonstrated full levitation, including the original team.

> Sure, metal ones are, but Are ceramic ferromagnets (without iron) common? That lone electron in an orbital is pretty important.

They literally reproduced this behavior with a substance that looks identical to the original LK-99, so while it would be quite unusual, it is clearly possible. Apparently ferromagnetism without any ferromagnetic compounds has been witnessed before, e.g. in ZnO.

squints... can't tell if this is sarcasm. Microstrategy is still trading at like 2x their BTC holdings and so on and so forth, the AI boom is still in-progress and imo the jury is still out on the actual, real-world and $ implications... I think it's sarcasm.

After reading the r/physics thread on LK-99 [1] I've cooled significantly on the matter. Basically: people who work in SC think the initial science seems very sloppy and the replication attempts don't come close to what you need to demonstrate a RT SC [1] https://www.reddit.com/r/Physics/comments/15i3h9d/lk99_megat...

Yet somehow those "SC people" issue this opinion without having seen the final paper nor the lab data on the original sample, which is presently being examined as part of the peer review process in SK?

wasn't trying to go political, but used it as an example of the evidence not fitting your theory. so it's still some what scientific.

Resolved in which way?

You know how there was a dotcom boom? Well the AI boom is just a repeat. Those who do not learn from history are doomed to repeat it. Save this comment and revist it in 5 years.
