What‘s the big deal about that superconductor stuff?

There’s been mixed results so far. The problem everyone is having is recreating the exact same material Lee and Kim did in their lab. Not only do they have to manage to add a copper atom in there, but it needs to be in the correct spot. That’s why we’re seeing different results everywhere as labs around the world are trying to recreate this material. We won’t know for sure until somebody can prove they created LK99.
