I got my PhD studying band structure of high-tc superconductors (experimentalist, ARPES). These Cu d-d interactions right at the fermi energy give me huge hope. Feels very familiar to other superconductors (re: all the cuprates). (Note: I specifically worked in a lab that was measuring a lot of the d-wave character / gap-energies of various superconductors) All in all, I'm now much more bullish on LK-99 being real su…

I think we're being trolled. Or trawled. Not sure which, yet. But the mention of Salvatore Cezar Pais in the patent should be enough to put this to bed for serious folks. https://news.ycombinator.com/item?id=36967333 In case you aren't familiar with the man's work, here are some highlights of his discoveries over the last decade: Conditional possibility of spacecraft propulsion at superluminal speeds High frequency g…

Would be pretty funny if this guy actually published a breakthrough that worked all of a sudden

I wonder why more people aren't talking about this

A lot of wishful thinking around these corners

Unidentified Flying Objects are absolutely real, though the newer cool kid term is UAP. (From the internet: UAP stands for "unidentified anomalous phenomena." ) It's flying saucers carrying aliens from another planet that's controversial and up for debate.

>It's flying saucers carrying aliens from another planet that's controversial and up for debate. Which is what "UFO" means to 99% of people.

But it's not what it means to the united states government when it announced it had seen UFOs, which is the point of discussion

This is probably a very stupid question, but why is simply measuring resistance not enough to conclusively prove that it is a superconductor. I mean, isn't zero resistance the defining property?

Well, I guess, that are islands of superconductivity and normal conductivity in the same sample.

This gives a low resistance and diamagnetism which is used as proxy to real superconductivity.

I may be wrong though.

Ultimately I'm glad that the research has seen the light, since I'm of the personal persuasion that there is no single scrap of science that should ever be done in the dark. All research, in a perfect world, would be entirely public and freely and easily accessible. With that being said, I'm not sure if leaking a paper and selfishly putting your name on it and excluding others so that you win a Nobel Prize doesn't ex…

The means justify the end. For all we know Lee and Kim would have sat on this for another year or more. I think that’s very understandable and I can’t fault them for wanting to be certain, given all the nasty things people have been saying about them, but the leak has clearly served humanity better than keeping it under wraps.

> but the leak has clearly served humanity better than keeping it under wraps.

Yeah, advancing human knowledge serves humanity, but unfortunately not really those who are advancing that knowledge. Those with money will just use your invention and make more money, you will have a pat on the back. I wish it was more balanced, we would have a lot of inventions sooner and implemented faster.

So theorically they agree with LK-99 reaching superconductivity?

I think that at least some parts of this material has superconductivity properties. That's why the videos shown have some very tiny speckles of the material showing the diamagnetism effects and just one anonymous video showing full levitation (type 2 superconductor property as I understood).

This ongoing research saga pretty much the most excited I’ve been about anything since before Covid. It feels like the science equivalent of watching your favorite sports team on an epic rise towards winning a world championship. Even if this turns out to flop, I hope history remembers the original authors favorably. They really did find something that by all accounts could plausibly be a room temp superconductor. An…

This is sad man. You’re getting excited at manufactured hype on twitter

I wouldn't read too much into this. You have to address prior art when it is found in patent examination as a part of application process, no matter how bogus it is.

It looks like the citation of the Pais patent was added by the examiner, rather than by the applicants. Does that make any difference in your view?

Uniformed opinion. It takes a week to bake/whatever a test sample. Which is why this is playing out so "slowly". So, they had an idea and have been baking/testing/refining samples for decades. Science and funding takes a while. What idea they started with and why they kept at it for 20 years is beyond me, that's a long time to chase an idea of you didn't have results or a hint that your idea would work. Maybe they ha…

Speaks to a supreme confidence in the theory, surely? I'm a layman but imagine everyone is going to want to hear every wild idea these guys could think up if this works out. They might have been sitting on this for 20 years? Probably why I'm not, but If I were any vc person I'd be busting down their door trying to give them all my money

How would you find such researchers if they didn't have plausible real-world results yet? I have a theory for new high performance heat engine which I developed over 15 years already, but I don't think anyone would give me ANY money for making a prototype (which may not work in reality), so I have to somehow do it in the limited time after working two jobs (I had to earn enough to have a home with a proper garage). Do you have any tips for someone like me?
