This is basically proof of room temperature superconductivity correct? (Of course assuming it isn't a hoax)
If all of this checks out, then it's a new era.
Funny enough this is a quote taken directly from the wikipedia article that Andercot linked, in the "loopholes" section:
>Earnshaw's theorem has no exceptions for non-moving permanent ferromagnets. However, Earnshaw's theorem does not necessarily apply to moving ferromagnets,[4] certain electromagnetic systems, pseudo-levitation and diamagnetic materials. These can thus seem to be exceptions, though in fact they exploit the constraints of the theorem.
...
>Diamagnetic materials are excepted because they exhibit only repulsion against the magnetic field, whereas the theorem requires materials that have both repulsion and attraction. An example of this is the famous levitating frog (see Diamagnetism).
The only examples I can find of stable non-superconductor diamagnets involved 4+ magnet arrays, though, or multipole magnets, e.g. https://phys.org/news/2014-08-diamagnetic-levitation-pyrolit... and not dipole configurations like this video seems to show.
But you CAN do it with concentric rings of magnets. Such magnets seem common for this exact demonstration actually. It doesn't look like one of those in the video though.
For now LK-99 is an material that displays some of the superconducting properties at room temperature.
Although generally the accepted method is that other labs reproduce it and that the paper passes peer review. Some videos aren't enough.

It's hard to understand how anyone would believe this, specially after so many other fakes
IMO there’s an awful lot of amateur / informal attempts that are promising enough that, while not convincing, are inspiring of hope. But I do wonder how much is fake. But more than a few seem to be clearly not fake, such as the work Varda is posting.
As for this video, well, it's like all the other ones that came before it, we'll know more once we have more data/videos/replication attempts.

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".
