Earlier quoted context omitted.

The source[0] seems to be the Douyin (TikTok) user 炼丹师阿翔[1], who also posted a different LK-99 demonstration video[2] a few days ago that shows similar results to previous demonstrations by other researchers. [0] https://www.douyin.com/video/7263715495256378659 [1] https://www.douyin.com/user/MS4wLjABAAAAJaTuSBArw0c6bK0eI9T1... [2] https://www.douyin.com/video/7262676385154583860

Yes but what research institute are they affiliated with? For all I know this is an pseudonymous TikTok user who is good at faking videos. Why should I take this for anything but complete fiction?

Certainly not making any claims of the legitimacy, just providing the original sources. There doesn't seem to be any attribution besides the anonymous account.

The Chinese subtitles in the first demonstration claim "further efforts will be made to reduce impurities", then the subsequent video claims "technical details will be published once they are properly organized and documented".

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.

It didn’t pin, it bounces, if it was flux pinning it would not bounce when you push it down.

Yeah, it's jumping back to a fixed position which isn't how I thought the Meissner effect worked. Since this seems to be posted by someone reputable though it's weird they missed that.

Alternative video link here, but it's in chinese so no idea if it gives any more information about the source: https://news.ycombinator.com/item?id=37010498

The video is watermarked 炼丹师阿翔 (Alchemist Axiang), which is also the username of the Douyin video, so I think that's the closest to the original source we can get. (The tweet claims Bilibili as the source, but it was apparently a live stream and 炼丹师阿翔's Bilibili account currently only has a previous video without full levitation. https://bilibili.com/video/BV1sM4y1H7MX )

Flux pinning doesn’t mean it can withstand all forces it just means it will return to where it was

What about those Flux pinned maglev "trains" you see on YouTube?

That's not true. Here's a video from a few years ago [showing a superconductor flux pinning](https://www.youtube.com/watch?v=OSojjjvRCR0). You can see from the video it's moving around. Also if it didn't move when you applied a force to it that would be quite the immovable object.

Another one that looks quite like the behavior shown here: https://www.youtube.com/watch?v=R2Hy6F_8n58
