    I have just watched a video about this. This is from the same group who claimed similar things in the past and were shown that the data was falsified. They had withdrawn the paper.

    So, until this is independently confirmed, I am really skeptical about this.

      I saw a tiktok about this that there were two separate papers published within the week as it looks like they were competing to take credit for the achievement, which would be unusual for bunk science.

      Not an endorsement by any means, but def paying closer attention than I would have.

      Edit: damn the LBNL is saying this might be legit

      You’re thinking about the University of Rochester group, which claimed room temperature high pressure superconductivity, and whose work was indeed riddled with fraud. This is a different group which claims room temperature and pressure superconductivity in a totally different material. They’re sketchy in different ways, but have not previously been down to be frauds (to my knowledge). At most, a bit cranky in their understanding of the underlying theory. Which is why several groups are keeping an open mind and trying to replicate this.

        A: there is minimal theoretic backing for this form of superconductivity.

        2: if this is true this is simply the largest case of utter dumb luck in the human species, like finding a convenient pill that makes you immortal, superintelligent, sexy and happy.

        But if tests prove there are 0 side effects I’m still going to use the magic pill.

        Half our most advanced materials science is in strained lattice, but this would still be incredible.

    Isn’t this the same paper that has been linked here multiple times in the past week? I can’t see anything new on there that wasn’t reported this time last week.

    Can someone eli5? I’m out of the loop and unfamiliar with superconductors…

      A superconductor is a special type of material that conducts electricity without losses, that means we can transfer electricity any distance we want without losing any of it to heat. That means we can make super efficient machines and even do things regular materials can’t, like create super strong magnetic fields which we then can use to make MRI scans of humans.

      More excitingly, superconductors do fucky things with magnetism, where you can get a magnet to lock in height and angle, essentially hovering, but still be able to follow a track, meaning levitating trains could become cheap and easy.

      Traditionally superconductors have only worked in super cold and/or low pressure environments, like 1-2 millidegrees above absolute zero, but some advances have made them work at higher temperatures like at about 20 degrees above absolute zero but under crushing pressures, which means it’s quite difficult and expensive to keep them superconductors, and they have to keep small so we can keep all of it cool.

      As we find ways to make superconductors for warmer temperatures, it’s easier to cool them and thus use them at scale and for everyday use. Suddenly you don’t need a train cart for cooling to keep hovering, and you could maybe even get a personal hover board or hover wheelys to zip around on.

      Superconductors also have other weird and cool properties that could let us do even more cool things as we find out more and can make bigger things with them.

    This is huge regardless but I wonder what the LK-99 material is like to produce and work with.

      Not hard, easier than what we do with microchips, apparently the current process yield is 10%, which is incredibly good for lab fabrication.
