New replication video coming from China https://twitter.com/lereguy/status/1686363900651151360
Hang on, wouldn't a sliver of any magnetic material behave like this within a moving magnetic field? This replication is a fail, yes?

#342I'm astounded that the MSM seems to be ignoring this ATM. I did a Google news search on LK-99 and saw nothing from major publications. A search on the NYTimes returned an article from 1974.

It's still not believed. It's just Twitter that I've seen the juicy stuff, like a (very sketchy) claimed replication from a Russian, and now another claim from a Chinese group. I could still see this being something "new" but not a true superconductor. If you read the link, there seems to be some kind of discovery brewing, but the original discovers may not have understood what they found.
While you're correct about the scarce and sketchy evidence currently it is in the process of narrowing down. Or to put it better the evidence is mounting that it might be a breakthrough. It likely hard to manufacture correctly, but simulations done at Berkeley Labs seem to support the claims of the original paper https://arxiv.org/abs/2307.16892 And aside from that to be honest I hope that we have time to prove or di…

Is your argument that China’s increasing technical prowess will not inevitably result in the US hegemony ending?
People said the same about Japan. The '80s and '90s was a bunch of media-fueled "the Japanese will run the world" hysteria. Japan is a technical powerhouse but that doesn't inevitably lead to ending hegemony. It requires a lot of other work too.

Japanese and South Korean increasing technical prowess didn't, why would Chinese be any different? China has serious fundamental problems and if you account for its gigantic population - it's seriously underachieving not only compared to US, but even compared to the rest of the developed world. It's fashionable to talk about China taking over, but it's far from guaranteed. China is pretty much confirmed to be falsify…
This statement would have been viewed as absolutely obvious and ridiculous 2 decades ago. The fact that it even needs to be said now is indicating how fast they are advancing.

One thing that has been constant for at least a decade or more is that every time a lab in China publishes even an incremental advance, a legion of internet commenters descends to declare the end of US hegemony because Americans didn't discover it first.

Not only is it a purported to be a room temperature super conductor, it's a relatively high temperature superconductor, not guarantee the effect goes away if you put it under a torch.
I think the critical temperature was 400 K (127 °C).

I want to believe. After several millennia of killing people for gold, we can finally put all that gold to good use—using it to create superconductors that can power energy weapons we can use to kill each other. ♫ It's the circle of life ♫
People cut cables for copper. Imagine what will happen with cables with gold.
