Interesting that the video of levitation isn't mentioned at all in this rebuttal.
Assuming the scientists acted in good faith and this isn't a complete scam, maybe we found something else that doesn't conform to our current understanding of superconductors, but does levitate over a magnetic field at ambient temp/pressure.
- tux3 3y agoOne response to the levitation video is that it is hard to distinguish from a non-superconductive diamagnetic effect, which can occur even in not very exotic materials. There are videos of graphite levitating that are circulating, for example.
- tigershark 3y agoNot true. The graphite needs two magnets, not one like in the video.
- trgern 3y agoThe video of “levitation” is one of the things that makes me, a complete ignoramus of the subject matter, skeptical. https://sciencecast.org/casts/suc384jly50n https://sciencecast.org/casts/suc384jly50n All other instances of “quantum levitation” that I have seen has a “locked in” effect: https://m.youtube.com/watch?v=Ws6AAhTw7RA https://m.youtube.com/watch?v=Ws6AAhTw7RA . Whereas the material in this video seems to bounce and warble in a way that appears to me more akin to standard static or magnetic repulsion. Hope I’m wrong.
