It looks convincing to my naive eyes, but how would you differentiate between this and diamagnetic levitation of something like pyrolitic graphite?
https://twitter.com/Andercot/status/1687748594563268608 seems to indicate that simply diamagnetic levitation cannot create the level of stability shown in this video.
I don't think that's right. Diamagnetic levitation is one of the ways you can get around Earshaw's theorem.
Funny enough this is a quote taken directly from the wikipedia article that Andercot linked, in the "loopholes" section:
>Earnshaw's theorem has no exceptions for non-moving permanent ferromagnets. However, Earnshaw's theorem does not necessarily apply to moving ferromagnets,[4] certain electromagnetic systems, pseudo-levitation and diamagnetic materials. These can thus seem to be exceptions, though in fact they exploit the constraints of the theorem.
...
>Diamagnetic materials are excepted because they exhibit only repulsion against the magnetic field, whereas the theorem requires materials that have both repulsion and attraction. An example of this is the famous levitating frog (see Diamagnetism).

Seriously? To me this looks like a chip of graphite glued to an invisible thread. The way the object moves is not what I would expect from magnetism (see second 10 for instance)
How can it look like something that is ostensibly invisible? It's not swinging around like a pendulum, so what exactly are you seeing that makes you think it looks like an invisible string?
The thread is horizontally positioned, left to right, not vertically.

>Do yourself a favor and look up how far away other stars are, consider how many times astronomers have looked into space and not seen aliens Exoplanets weren’t confirmed to exist until 1992. Just sayin’.
And our goggles to see far away aren't that great. We barely know anything about the surface of these planets. The main argument in favour of the non-existence of aliens are religious books.
>The main argument in favour of the non-existence of aliens are religious books.
Not in the slightest, that's the worst strawman against it (and for the record, I am an atheist, so drop this line of argument now before I'm forced to counter-insult you.) Try the Rare Earth Hypothesis. There are only 10^11 stars in the Milky Way galaxy, you don't need to stack up many terms in a "Drake equation" to push the result to near zero in the Milky Way. The Rare Earth Hypothesis is consistent with all empirical observations thusfar.
Furthermore, even if there were other intelligence species like us in our Galaxy, they would be incapable of reaching us just as we are incapable of reaching them. To believe these aliens are visiting Earth you need to explain why you can't see them anywhere except ostensibly in deserts above American military facilities and installations for testing secret aircraft.

#85Is this material safe to handle? It feels like this thing soon will start appearing all over ebay and aliexpress
I hope it is. It will be a perfect toy for little kids, right along the little ball magnets.

#86It's hard to imagine how this could be faked short of digital manipulation, and it seems implausible that it would be a known high TC superconductor because it would warm up too fast. Absent the former explantation, I'm starting to believe this is real. Also, it's not like all the author's are unknown hacks. Hyun Tak Kim has about 10k citations (Google scholar, which sometimes combines people who have the same name t…
According to this video: https://twitter.com/xmal/status/1300754522218913799 it is possible to have stable levitation using a copper plate below the magnet.
OP's video has two stacked metal objects – could the lower one possibly contain copper?

Have you watched other videos of flux pinning? This sure looks like those to me, it's a weird phenomenon.

As revolutionary as this stuff is, it fits within our current understanding of the universe, or maybe a tiny bit outside (for now). Intelligent interstellar aliens using unfathomable technology, secretly interacting with humans doesn’t. What you’re asserting at this point is that all of science as we know it is wrong, and everything we’ve built was just incredible, one-in-a-trillion fortune that any of it worked at a…
>everything we’ve built was just incredible, one-in-a-trillion fortune that any of it worked at all. That’s not how revision in science works. We know that Newtonian mechanics was wrong and incomplete, but at the same time, it didn’t work by “luck” either.
That’s exactly how revision in science works; incomplete is wildly different from “wrong”, and most of our understanding of science would need to be fully wrong for aliens to do what is claimed they can do, to the point where we would have needed to get impossibly lucky in order to have built the things we have.

Would that be legal, considering they have a patent (pending) for it? Not denying it won't appear anyway just curious
I'm not sure how it works, but this was the first result: > Patents are territorial and must be filed in each country where protection is sought. [0] https://www.stopfakes.gov/article?id=Is-My-US-Patent-Good-in...
Not a patent attorney, but as far as I know: The patent is currently pending (as in, being evaluated to see if it will be granted). Once it is granted in one country it can be expanded to multiple countries within a couple of months, given that the first country is part of the Patent Cooperation Treaty. So if an invention is marked “patent pending”, you know you will have the risk of being sued by said company at some time in the future if you copy the invention.

Flux pinning doesn’t mean it can withstand all forces it just means it will return to where it was
What about those Flux pinned maglev "trains" you see on YouTube?
The idea of those (i.e. like this https://www.youtube.com/watch?v=AWojYBhvfjM&vl=en) is that they're an example of equi-potential behavior.
The superconductor can move because it's staying at a consistent height.
The video linked is also pretty good at showing similar behaviors to the sample of LK99 we see claimed in the video: the superconductor can wobble, shake and does return to it's original position (or tries to) - but it's got a lot more mass.
