That is not possible in any known material. Unless thats an array of very elaborate fakes, its a RT superconductor.
But the simulation papers and conductance tests make me suspect its a topological superconductor that would fail such tests.
One of those has already been admitted to being outright faked:

I am on mobile now, I will have to go back through my history and check the claims... But one such reproduction is from the Meissner or Bust channel. They have been documenting the production for days, and IIRC they showed full levitation on a single magnet.

So, some other material levitating itself in seemingly room temperature?
Currently this guy is practically using his real name, with his university and professor exposed. It takes some courage to lie at this point.

Edit: People sometimes speak in convoluted ways. I feel "The sample was not LK99" could have two interpretations here: 1. It is a completely different compound. 2. It is a derivative from LK99 with a different synthesis/doping method.
No, it doesn't. It is a nine second video. Not a research paper. Right now the topic is being hyped up and you might care but next year nobody is going to give a damn about some random video uploaded to bilibili.
Why does everyone on HN pretend that even the smallest of missteps is going to end a reserachers career and therefore even videos with almost no effort put into them, that to feed the rumor mills, are somehow the paragon of truth?
We’ve seen proper levitation of specks that hasn’t been falsified yet.
That said, I believe theory has shown it’s actually possible for a diamagnetic object to fully levitate over a magnet as long as it’s light enough, but unlike a flux-pinned superconductor, it will only levitate over the center of the magnet, as is happening in all the levitation videos.
You’d think that with the current excitement and relative simplicity of the apparatus, labs all over would be putting in some weekend hours to muck about.
Consistency might be a problem for fabrication and commercialization.
That's unfortunately not how science is incentivized.
The lab reproducing this would get exactly zero academic credit. Maybe a day of press fame, but that's it.
On the other hand, once/if this is proven to be real, there would be thousands of labs racing to improve it and cite each other's work.
Do you have a link to more than one showing complete levitation?
