Beijing Superconductor (LK-99) Levitation Video Author Admits Fraud, Takes it Down

  Is there a word for something that is disappointing but simultaneously unsurprising?

    Inevitable?

    It’s worth pointing out that all this is is the video from the Beijing example which I honestly haven’t even heard about. This does not mean the product itself is a fraud which I’m sure people are going to jump up and down on.

    Unsurpointing.

    If it is disappointing it doesn’t fulfill your expectations. But if you expected it to happen then it’s not disappointing

      Not really, disappointing also includes a failure to fulfill hopes, not just expectations. You can expect an outcome and also be disappointed by it.

  So… how much ya wanna bet this guy faked up the video to secure/maintain funding, and didn’t quite realize how far it’d go ….

  … and back tracked as soon as they realized there was about to be a shitload of scrutiny.

      oh absolutely.

    I should release my paper about how I turned lead into gold. Nobody would care about that one, right?

    • FuglyDuck@lemmy.world ⁨1⁩ ⁨year⁩ ago

      well, it’s already been done. (well, that may not be what’s going on in the article, but the particle accelerators have created gold… by doing their smashy-smashy thing)(I’m sure the physicists love it when we reduce decades of their work to sounding like toddlers smacking stuff together to see what happens… it’s really grown up serious science!)

  China and fraud - like peanut butter and jelly, they just go together naturally

  This is the best summary I could come up with:

  ---

  The original poster of one of the Billibilli videos circulating on the Internet and seemingly proving LK-99’s levitation ability has come forward, and admitted his clip was a hoax.

  The video in question is allegedly from the University of Science and Technology in Beijing and purports to show a small black substance floating in the air as it follows a magnet.

  Whenever a claim as momentous and potentially civilization-changing such as “we’ve found the world’s first room-temperature superconductor” is made, noise is bound to follow.

  But even focusing on the hard science (which we want to be clear, replicable, and truthful) and moving on to the boundaries of peer-review scientific process, it becomes difficult to deal with the noise.

  Neither the cooking time (how long at what temperatures the mixtures have to stay within a vacuum oven for LK-99 to be synthesized and whether there’s thermal variation at any moment) nor the quench rate (the same, but when it needs to cool down) are, however, well-documented.

  The video poster ultimately claimed that the experience of being a part of the noise had changed him, and that he’d be more cautious with his actions and words in the future.

    Fraud in China. Huh.

      They better be careful otherwise the world won’t take them seriously anymore, oh wait.

    I felt bad for scanning the big list for replication results that weren’t Chinese 😞

    turns out I was right

  Question for clarity, does it’s levation have anything to do with whether or not it’s a superconductor?

    What I’ve gathered from many of the discussions around this topic is that thr levitation is a notable feature of superconductors due to th Meissner(?) Effect. So if it couldnt levitate, there would be no reason to suspect that it is a superconductor. Because it does levitate, superconductivity is one of a few possibilities.

    There have been indicators it may be a semiconductor instead, but apparently the conditions to accirately produce the material are vague/not fully understood - so attempts at reproduction have failed to rule it in or out 100%

      Which is also sadly a common component of hoaxes like this, include some vague component so you can just claim your detractors are doing it wrong.

      Very interesting, had no idea of the meissner effect. Thanks!

  I think we’re starting to lose the bigger picture - Re-read that first sentence after the headline (emphasis mine):

  “This is only one of several videos from different sources claiming to show the substance levitating.”

  This isn’t about LK-99 per se, but one of the videos that came after the announcement, likely trying to capitalize on it if only for views. There’s still hope LK-99 can be corroborated.
