This is basically proof of room temperature superconductivity correct? (Of course assuming it isn't a hoax)

No, it is not yet proof of superconductivity. It also requires measurements of the electric resistance as function of the temperature.

For now LK-99 is an material that displays some of the superconducting properties at room temperature.

Nitter: https://nitter.net/Andercot/status/1687740396691185664

OT but why do I need to press "enable this playback" and reload the page to view the clip? What does it do?

HLS is a way to serve a video in chunks over HTTP. It's how livestreams are implemented in most places. Twitter serves videos in HLS chunks, but Nitter doesn't want to proxy it to you because videos take a lot of bandwidth. In order to let you choose whether you want to connect to Twitter servers, it first asks you whether you want to enable playback.

Assuming everything in the video is real, the only remaining question is: what is the actual temperature of that sample? If all of this checks out, then it's a new era.

It looks convincing to my naive eyes, but how would you differentiate between this and diamagnetic levitation of something like pyrolitic graphite?

https://twitter.com/Andercot/status/1687748594563268608 seems to indicate that simply diamagnetic levitation cannot create the level of stability shown in this video.

No, the video contains no information about its conductivity.

It's hard to imagine how this could be faked short of digital manipulation, and it seems implausible that it would be a known high TC superconductor because it would warm up too fast. Absent the former explantation, I'm starting to believe this is real. Also, it's not like all the author's are unknown hacks.

> Hyun Tak Kim has about 10k citations (Google scholar, which sometimes combines people who have the same name though) and authored a paper in scientific reports which got L&K interested in collaborating with him. It appears he was a latecomer to the project, mostly borrowing his reputation to the trio of anonymous, non anglosphere native original authors.

Let's be less cynical. Nothing to do with borrowing reputation.

The original authors have something. They don't have the expertise in condensed matter physics to really know what. They don't know how to report results and what results would be conclusive. Their work is simply not convincing, and if they were experts they would also not be convinced.

That's why they brought in another collaborator who is an expert. But because the paper was released early it's clearly a mess. You can see the big quality improvement though just between the two drafts.

I’d rather evoke “alchemy” if we’re going to reach for the non-scientific magic explanations.

At least in the alchemy camp we have minds like Isaac Newton. On the UFO side it's mostly hucksters and numpties commenting "wake up sheeple, you can see it's CGI" on ISS live stream videos.

In the meantime there is no irrefutable proof

Even a breakaway civilization of ancient Atlaneans living under Antarctica makes more sense than aliens. Do yourself a favor and look up how far away other stars are, consider how many times astronomers have looked into space and not seen aliens, and then ask yourself why aliens would be so good at cloaking themselves in space but would ostensibly let themselves be seen on Earth itself. Spoilers: it's not Atlanteans…

>Do yourself a favor and look up how far away other stars are, consider how many times astronomers have looked into space and not seen aliens Exoplanets weren’t confirmed to exist until 1992. Just sayin’.

And our goggles to see far away aren't that great. We barely know anything about the surface of these planets.

The main argument in favour of the non-existence of aliens are religious books.

Seriously? To me this looks like a chip of graphite glued to an invisible thread. The way the object moves is not what I would expect from magnetism (see second 10 for instance)

How can it look like something that is ostensibly invisible? It's not swinging around like a pendulum, so what exactly are you seeing that makes you think it looks like an invisible string?
