A Korean superconductivity academic body invalidated the research results from a team of Korean researchers claiming to have developed a room-temperature superconductor in its preliminary assessment.
We have seen a bunch of samples float, and we have seen papers detect no superconductivity on samples that don’t float. The missing damning evidence would be a paper that manages to produce samples that do float but aren’t superconducting. Instead we are getting a slow trickle of reasons why other causes for the material to float are less and less likely, while superconductivit in lk99 is still perfectly plausible. Not to mention the various theoretical papers that also seem to indicate very high temperature superconductivity is plausible to expected in lk99.
On top of all that there is a second group that has a prepub paper showing high temperature superconductivity.
For this to turn into a nothing burger either all the various observed cases of levitation would all have to be wrong somehow, or despite all theoretical expectations this material would have to be diamagnetic, while also being a high temperature superconductor (which is a pretty rare combination of properties on top), or the paper measuring high temperature superconductivity would have to be wrong and still despite all theoretical expectations this material would have to be diamagnetic not superconducting even though our (admitedly flawed) models indicate the reverse.
