So, yesterday the pre-review paper, today the uTube video?
Also, is it really “levitation” when the heaviest point on the sample remains in constant contact with the material?
Yes, just because the force isn't completely lifting it's own weight doesn't mean it's not superconducting.
As the article of @bane_killgrind@lemmy.ml says it is because
They claim that the levitation was only partial because of impurities in their material.
