Why would other teams be observing floating at room temp? Is it possible to have a diamagnet that becomes a superconductor?

  It’s possible there are tiny bits of superconducting stuff at room temperature which connect into bigger and bigger bits as temperature drops, until it starts working as a whole at 110K. Maybe. Don’t quote me.

    That would suggest that a very high quality sample would superconduct at room temperature.

      Not necessarily, but possibly.

      Unless the "low quality" part is actually causing the superconductivity. Remember the multiple simulations that showed Cu replacing Pb at a less favorable site (energetically) was better for superconductivity than at a more favorable site. It's possible "high quality" samples actually have less "imperfections", which seem important for the superconductivity.

        Exactly it's quite possible that 'worse' is actually 'better' and vv. I'm sure that it won't be long before that will be resolved though, this is all happening so fast that such important answers will be sought by more than one team.

    Due to how these materials behave, this likely means you can manufacture a real-deal UFO in orbit…

    what? give me an effective field theory for that lol because that is not a thing

      Of course I can't but https://www.nature.com/articles/s41467-018-06707-y https://www.nature.com/articles/s41467-018-06707-y maybe
