I've seen people saying this on Twitter and elsewhere, where are we back from?

It's a split meme that refers to the emotional rollercoaster of a prolonged uncertain situation whenever news come in.

Its two parts are "It's so over" when there's bad news and "We're so back" when there's good news.

Back to annoy us with inane Twitterisms, I reckon.

It is kinda funny once you get used to it. When there is bad news they say “it’s so over” and good news “we’re so back”. The emotional rollercoaster on LK-99 is pretty intense and these phrases capture that for people. I get it at this point.

This is basically proof of room temperature superconductivity correct? (Of course assuming it isn't a hoax)

This is an hoax and it's sad to see people like Sabine Hossenfelder falling for it so easily: - video recorder in a kitchen or living room - created by some random tiktok account - no credentials, no description - tagged "mysterious" It's hard to understand how anyone would believe this, specially after so many other fakes

I see no indication that it was filmed in a kitchen or living room.

So it's the same as the Bob Ross memes of "Ruined", then :)

In fact I see some serious lab quality glassware in the background. But posting without its provenance is a weird for sure.

IMO there’s an awful lot of amateur / informal attempts that are promising enough that, while not convincing, are inspiring of hope. But I do wonder how much is fake. But more than a few seem to be clearly not fake, such as the work Varda is posting.

Assuming everything in the video is real, the only remaining question is: what is the actual temperature of that sample? If all of this checks out, then it's a new era.

Such tiny samples warm up to room temperature very quickly, on the order of a few seconds. In my experience, it's not possible to make such small pieces of YBCO superconductor levitate, they warm up too fast.
