Small-Scale Question Sunday for July 23, 2023

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?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

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 It's not peer-reviewed, published, or replicated yet--what do you guys think the odds are that this is legit?

And another claimed semi-replication by randos, supposedly using a different approach and getting their sample entirely floating off the surface. It still looks a little different than most flux pinning examples I can find, but going to need either someone to scale up meaningful production sizes, or a more specialized lab looking at other traits used to identify superconductivity.
