Claimed room-temperature superconductor LK-99, discovered by a South Korean team, sparks viral buzz but faces skepticism. The material, a copper-lead-phosphorus-oxygen compound, exhibits supposed superconductivity at up to 127°C. Initial replication attempts by Indian and Chinese teams fail to observe superconductivity, although one notes low resistance at -163°C. Theoretical analyses hint at interesting electronic features, but consensus on crystal structure is lacking. Unverified videos of levitating samples circulate online. Scientists caution against overhyping, recalling past unsubstantiated claims. While attention is high, doubts persist amid scientific and online communities, leading to humorous responses mocking levitation videos.
