And how is this different than LK-99, which was pretty conclusively proven to not be superconductive?
Lots of geaphs instead of a photo of a hovering piece of metal. And they are more careful with wording, 'possible Meissner effect' is less headline-catching than 'wow we discovered a superconductor'
Yeah, the last one was sensationalized to the point it felt like dishonesty (and, quite possibly, was). But when something like this comes up, it’s still important to put it out there. The more eyes on it, the better.
It has already replicated, with two separate labs in China confirming the results. When LK-99 was announced, it was still awaiting replication. The chemical difference appears to be that this thing has sulphur where LK-99 did not.
