Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.

Don’t be. Twitter/X/whatever they’re calling it this week is crawling with Pepe investment bros talking about bullish sentiment because superconductors equals singularity musk crypto AI blah blah blah. It’s bad. It’s really, really bad.

That sounds like a good reason not to visit Twitter/X/whatever.

AI has already taken over the internet and is just feeding us news stories based on what it already knows.

Super conductor discovered by a team who's been searching for 20 years. Internal conflict 'proves' there's something to argue over. Low quality, confusing information that's hard to decipher, but kind of makes sense. Asian language information streams and videos.

Musk buys twitter.

A submarine visited the titanic and imploded.

With all the recent “the government has alien spacecraft news” and the bizarre circumstances of this material’s creation, the (I know to be ridiculous) conspiratorial part of my mind is going “I guess climate change is finally forcing them to take stuff out of the extraterrestrial vaults.”

So they planted this with a Korean lab a few years ago?

Why are they all from China? Why are they able to replicate so much faster than US labs?

Everyone with half a brain in the US is working the ad-tech and data-mining industries, that's where the money is.

To be fair, China also has an extensive state surveillance apparatus. They just have their military and security agencies run it out in the open at much lower cost. The obfuscation in the US is much more expensive to maintain, but necessary for the illusory veneer of privacy and “freedom.”

... or Gödel was right and the universe spins and backward time travel is possible and they got permission to pull some future inventions out of the vault retrieved from future us ... in order to make sure we actually make it to future us ... which we should ... because the inventions are real ...

Can someone explain how this video shows superconductivity?

[not an expert but...]It shows strong diamagnetism(being repelled by both of the poles of a magnet), which is a property of superconductors. Not necessarily a superconductor though, that’s still to be established but at least it shows that the inventors are up to something and it’s not complete fabrication.

Why don’t they try heating it and seeing if the effect goes away? You could even try a welding torch or something.

If it's real, how fast could we see concrete applications using this material? 5-year time frame? 10-year time frame? More?

Nobody knows, it depends on a multitude of factors, but most likely this won't be the exact material which will have applications, I'm sure there is a much easier to fabricate related material which will be the first of a whole set of materials which act as superconductors at room temperatures.

I still have a very, very hard time understanding what all of this means. Is there an easy to understand explanation for a room temperature superconductor?

IANAP, but a layman's understanding: the materials that we have available today to conduct electricity at or around room temperatures largely do so in an inefficient manner. As electricity moves through the material, some energy is wasted in the form of ejected heat. To circumvent this, physicists discovered superconductivity: a state in which a material is a perfectly efficient conductor of electricity. Thus far, to…

"Inefficient" is a rather relative term here, since batteries, motors, and transmission wires are >=95% efficient already.
