Technically it can be done with an array of magnets with opposing polarities.
Without more details from on this video's source and legitimacy, one could argue that an array of magnets is hiding under the 'single magnet' cover plate.
I am not saying this is a hoax, but as exciting as this seems we just have to wait it out for more replication publications to make that call.

- hoseja 3y agoNo, it mathematically cannot be done with any combination of permanent magnets.
- gpderetta 3y agoaside from non-superconducting diamagnetic materials, I think it can be done with non-static magnets, for example: https://en.wikipedia.org/wiki/Spin-stabilized_magnetic_levitation https://en.wikipedia.org/wiki/Spin-stabilized_magnetic_levit...
- hoseja 3y agoOh of course. Brainfarted and fused "static permanent magnets" into just "permanent magnets".
- kaba0 3y agoIf we doubt the legitimacy of basic claims like a fair setup of magnets, then there are much easier ways to create a fake, like just tie something on top of it.. but why would we doubt the legitimacy of reliable institutions?
- DoingIsLearning 3y agoGrand parent was saying it's "impossible". I say it is _technically_ possible. To which I added: "I am not saying this is a hoax, but as exciting as this seems we just have to wait it out for more replication publications to make that call" It has been a little over 2 weeks since the first pre-print from Korea University. The hashing out of a fabrication process with less impurities will be a long process. My point is not that everyone is pulling a con, my point is that we need to wait it out.
