The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 5 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Chamath predicts LK-99 is merely diamagnetic, not a superconductor
“My intuition on this is that this is diamagnetic. And I think we're gonna find that, you know, it was, it's like yet another material added to the list of materials, and it's okay.”
Friedberg: Five labs published modeling papers supporting LK-99 superconductivity
“Five different labs have now published papers that show that the way that this material is supposedly produced, it should create these pathways or these energy states with the electrons that theoretically could enable superconductivity at a very high temperatu…”
Friedberg: Simulations show LK-99 requires precise lead-atom replacement to superconduct
“The simulation showed that you have to replace only one of the lead atoms, not any of the other ones, in order for this to work. And that could explain why everyone's having different results in the lab trying to reproduce this.”
Friedberg: No lab has replicated LK-99 zero resistance at room temperature
“No one's yet replicated this at room temperature.”
Friedberg: Chinese lab observed LK-99 superconductivity at 100 degrees below zero Celsius
“There was a lab yesterday in China that published no resistance, but they had to cool it down to a hundred degrees below freezing, and so it wasn't at room temperature, but it did superconduct, it did have no resistance.”
