Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

Room-temperature and pressure superconductor discovered. It's not peer-reviewed, published, or replicated yet--what do you guys think the odds are that this is legit?
Replication of the semi-floating behavior, but (very) high (and increasing with decreasing temperature) resistance and evidence of ferromagnetism in addition to unusually high diagmagnetic behavior from a Chinese group. Their theory involves a complex scenario of ferromagnetic (maybe ferrimagnetic?) forces causing the specific half-floating behavior through torque, without much relevant impact from the large diagmagnetic components -- definitely a weird physics thing in general, and doubly so for a compound where none of the input ingredients were ferromagnetic (and many not even paramagnetic: lead, copper, and solid sulfur are all diamagnetic), but not something quite so obviously useful.
I'd be interested to see further experimentation, but it's a big impact in favor of 'weird and genuine thing, but not superconductivity' side. On the other hand, the difference between their temp vs resistance graph and most other replications is surprising : erroneous zero or near zero values are pretty common with resistance measures, but you don’t usually see entirely different slopes, which leaves open questions about contamination.
