But couldn't it just be a magnet ? I don't understand how it's a proof. You can already do what is in the video (and even better), with for example, pyrolitic carbon ? https://en.wikipedia.org/wiki/Pyrolytic_carbon

It’s not proof, but if it wasn’t even diamagnetic it would be over. It couldn't just be a magnet, it is repelled from both ends of a normal magnet, according to Chinese lab videos you can find in the thread.

Lead weighs a lot more than pyrolytic carbon.

Have you seen videos of pyrolytic carbon? A thin sliver of it barely hovers on top of a huge magnet. It doesn’t stand erect. Same effect as LK99 but much smaller magnitude.

No, digmagnetic of levitation requires multiple magnets in a halbac array: https://www.kjmagnetics.com/blog.asp?p=diamagnetic-levitatio...
