Earlier quoted context omitted.

A material with no electrical resistance. Build a wire out of it and the voltage will be the same on both ends.

And the voltage will be the same on both ends when it has current flowing through it .

The only thing that holds a voltage without current flowing through it is an insulator.

The method to produce this material as described in the related paper [1] is fairly simple and could be done at home with a $200 home metal melting furnace from amazon and the precursors (which also seem to be fairly standard easy to obtain metals). If this is real, I'd expect some smart people from hackaday / youtube to reproduce this within weeks if not days. If this is real, it'll change society quickly and perman…

Ok, let me just add the obvious disclaimer: don't try this yourself unless you have a pretty good understanding of chemical lab safety. Really. It's more likely that you will contaminate your land, and possibly your neighbors land too than that you will manage to replicate it.

Video: https://www.youtube.com/watch?v=EtVjGWpbE7k I really need someone to bring me down a notch. This is too exciting!

That video isn't very convincing. The usual test is that the material can float above the magnet.

What do you suppose the odds are that there's a Tin-based compound instead of lead based?

(Which would effectively make a bizarre form of brass a superconductor)

If iron was worth naming an era after this will be.

But they've trademarked the name KL-99 (®) in their follow-up paper: https://arxiv.org/pdf/2307.12037.pdf

Stone age

Bronze age

Iron age

LK-99 (®) age

The effect is weak, but seeing that it behaves the same by flipping the magnet means that it can't be a standard magnet like we're used to seeing. (If I understood some of the other comments correctly). Other comments. https://news.ycombinator.com/item?id=36867758

Copper does this already. It's not like ferromagnets. https://www.youtube.com/watch?v=sENgdSF8ppA

In the video, it's when they stop moving the magnet, it maintains its position, neither repelling nor attracting.

Several physicists have spoken up and said this, and a few other tells distinguishes it from any conventional materials, which is why they made the video to begin with I'm sure.

That said I'm just parroting back the things I've picked up from this discussion.
