To create such a dramatic increase in critical temperature, I would expect you need a dramatic change in chemistry (as in: formula, materials,...) as well.

I mean it's not even the same basic elements. How much more of a dramatic change were you thinking?

Well, last time I had some hope for room temperature superconductors that was with doped fullerenes (C60 and friends). That was a truly novel approach.

So, has anyone seen any of the replication studies start coming in yet? From what I've read we seem to be waiting on those. (and I think they're likely coming today or tomorrow?)

I'm following this fellow: https://twitter.com/andrewmccalip Seems to have the right energy [edit thanks folks] https://nitter.net/i/status/1684433849781202944 Here’s a more colorful play by play as well: https://nitter.net/8teapi/status/1684586672917565443

This is amazing thank you for the link. Absolutely wild time to be alive

> My issue here is: This new material is essentially standard "high temperature" YBCO superconductor material just slightly modified, or? The authors are not doing anything dramatically new, like a new chemistry. There is no Pb in YBCO, what are you on about?

That is what I would call a slightly modified approach. They just "bake something together" and hope to get lucky. No way. Anyway, I am not an expert. I hope they have a win here, but hard to believe at this point.

AIUI The only thing in common is they both contain copper.

Not an expert either, and extremely skeptical myself. The poor videos claiming to demonstrate levitation just seemed to show diamagnetism and eddy current reactions.

LOL they really renamed it X? I see they even bought x.com which surely they paid some ridiculous amount for, and yet they wasn’t able to spend any cent on original logo, at least X.org logo as an orange O.

Elon has personally owned x.com for a number of years now. Timeline as I remember it is Elon bought it in the late 90's, it changed hands when paypal merged with Elon's payment company, then he bought it back in 2017ish

Still make me laugh. I doubt the 2017 transfer costed $10. Let’s just recall all the more that domains are never really own, and that seems all the more crazy to my mind. Though I guess that when you let single individuals able to claim indefinitely large amount of ownership, that’s unavoidable waste of resources.

Just for fun: Am I the only one who thinks there's connection between this and the UAP news that's coming out? RTSC would probably enable a lot of incredible energy & maneuverability capabilities... Sorry, indulging in a little off-topic conspiracy theorizing.

We haven't had "the beginning of AGI" and there is no reason cheaper electricity would "destabilize society".

A source (German) attributed to the Max Planck Institute for Solid State Research thinks the paper is bogus [0] [0] https://blog.fefe.de/?ts=9a3f8740

Appreciate whatever this dude is trying to say in their blog, but judging by his writing style and overall presence and demeanor, he doesn't really want to be listened to, does he?

Conduct electricity with zero resistance. This has been possible at cryogenic temperatures (powers supermagnets, MRI etc) but running at room temperature _and pressure_ means in theory that you don’t need expensive support machinery. Has been the holy grail for the field. If true, this specific case is only low current, but demonstrates such a thing is possible - almost certainly winning an instant Nobel Prize.

Does this mean there would be no heat waste? And devices like phones and computers wouldn't get hot?

Computers would still get hot, because the main cause of heat is not resistance in wires, it's that when a transistor switches with charge in the gate, you need to dump that charge, and when you do this it turns to heat.

They would get less hot, because there are plenty of transmission losses too.

What if the team itself did create LK-99 that is a superconductor, but they aren't able to reproduce it and only have the sample left that works. Hence, they aren't able to make more of it to prove their success, but rather decided to release the paper and method so that others can try to reproduce it. Given the amount of interest, they could put hundreds of labs to work trying to recreate what they themselves can't, hoping someone will find what they found and have an actual process for doing so?

Is that even possible?

I am going to attempt to address the common nitpicks in one fell swoop: 1. Rushed publication, plot quality, grammar, etc. Get over yourselves. This is a pre-print for an instant-Nobel, next-tier-of-civilization level discovery. The proper publication will come in due time. Waiting for a more complete verification is a sheltered view. Being first matters. Things changed after the J/Psi discovery in 1974. For those th…

What do you think the chances are of it being a measurement/instruments error? Edited to add: I am not a physicist. I don't know the subtleties of measuring experiments, and it was not my intention to state that there was a measurement error. I just wanted to ask someone for their assessment of the chances it was an error. It's a little depressing that people are so quick to assume the worst of others, but I get why.…

IANAS, but science Twitter seems to think 1) authors aren't clowns but 2) there's a non-zero chance they've misinterpreted non-SC effects because 3) there's missing or inconsistent data that would conclusively prove SC

We aren't even close to the beginnings of AGI. An LLM is no closer to AGI than a model T is to a space elevator.
