I don't see why people go crazy over this, the meissner effect in superconductors look different.

I don't understand what you're not seeing. Nobody is saying that the whole LK-99 sample is superconducting. Why would you expect the whole sample to float, instead of "partial floating" as we're seeing, if you have a material that's only partially superconducting?

I was wondering this, why do all the samples not completely float. If the sample is only partially superconducting, could you just smash it into smaller pieces and find a few floating ones? Or would the different domains be so small that you have to turn the sample into dust before you get a completely superconducting piece? Probably can not be answered in general as it heavily depends on the synthesis process?

pardon my ignorance but why are people posting nitter links every time, what is wrong with original twitter urls?

Twitter nowadays is much more strict about rate limits from non-logged-in clients.

Twitter tries to force sign in/up, when you scroll down through replies.

This allows people without a Twitter account to read tweets and replies. Also, some people (as myself) have blocked Twitter.

That's what is currently being done! A few videos have surfaced of smaller grains of LK-99 fully levitating. We're waiting for additional confirmation.

Twitter is basically broken if you don't login, compare this:

In Twitter the latest tweet I see is from July, in Nitter is 22 minutes ago. Additionally in Twitter I get 3 notices/popups that I need to close.

[flagged]

Clicked through 3 links to be greeted with "Disclaimer: I’m no physicist nor chemist...It turned out that LK folks were not talking about some stupid shit."

-- combined with "(Note: was written and published hours before this demonstration.)", and there wasn't an attempt to explain the connection between TFA and this new other article I'm supposed to read.

I'm good, thanks.
