Has anyone even seen a ferromagnet stand up like that in a magnetic field?
And this new paper finally rigorously explains away all the half-levitation videos. They can no longer be considered any evidence of SC at all.
At this point we have many examples where it's fully levitated.
No credible reproduction has featured a levitating sample.
This paper doesn’t explain away anything yet - they’re conjecturing based on their experience with their sample. Their conjectures are no more credible than the opposing supporting conjectures.
IANAP and I don’t have a horse in the race, and while I’m excited to see if this is true, I don’t believe anything other than there’s a long road of research ahead and nothing will be proven with hottake nitter videos or hottake preprints.
Andrew McCalip himself says this explains everything he's seen.

> That said, I think we're getting to the point where magnetic observations may be adding more noise than signal. Yesterday, I did perform the pole flip that was discussed in the last video. Very important to note, however, that ferromagnetism can exhibit pole agnostic behavior too. Check out the excellent video by @vangennepS. nitter.net/vangennepd/statu…. While the amateur magnetics method was fun to try for a screening method, it seems to have too many false positives to be entirely trustworthy.
That’s not at all supportive of “explains everything I’ve seen”
He's been looking for an explanation of this sort for a while:
"I'm still suspecting it's a magnetic phenomena that's not SC" https://nitter.net/andrewmccalip/status/1687887799872294912
"I don't want to succumb to the echo chamber just yet, it seems weird, but could we explain this another way? Is there a lead compound that exhibits ferromagnetic behavior?" https://nitter.net/andrewmccalip/status/1687497082322788352
Still, his phrasing doesn’t indicate it’s over for him, just bordering - perhaps explains everything they’re seeing, but it’s :
* not LK99
* a conjecture
* isolated to magnetic properties that are acknowledged to be novel and don’t rule out messier effect
* ignore other claimed properties like resistivity
Also, something explaining everything you are seeing is again a demonstration of an alternative, as is evinced by the material not being LK99, that claimed LK99 as a ceramic without a reliable method of production with a claimed low production rate (less than 10% of runs claimed by the original authors, with them claiming to have done over 1000 runs to produce their sample).
Again: I think it’s time for science to take the helm and hottakes to take a back seat for a while. I expect we will have something noteworthy either way by the end of the year. By the end of the month conclusions are fun gimmicks. I’m down with fun and love a good gimmick, but I’ll withhold belief in either direction until the original teams paper is released, their claimed sample is analyzed independently, more details of the claimed process are released to allow replication, and any novel properties have a stronger theoretical explanation. It’s extraordinarily unlikely they have found a room temperature super conductors, but not impossible. Regardless, they’ve discovered something novel and that, by definition to any scientist, is interesting.
It has been time for that from day #1. It either exists or it doesn't. Whatever people think won't make a shred of a difference and until there is replication if you want to look smart without doing any work you can pick 'it isn't real' (but boy will you look stupid if it eventually is) or 'it is real' (but boy will you look stupid if it eventually isn't).
I think all this whole saga has done for me is to show how little patience people have and how even findings of fact can lead to polarization if there is an element of uncertainty thrown into the mix.
But it's proof that the proposed explanation is not a bulletproof proof... Because it could also be any other alternative effect.
That's literally the whole point of it...
Rest are just hints.
5 years and still has current
Starting to remind me of the logic of the witch test in monty python and the holy grail.
