When I first saw the quoted resistivity, 0.002 ohms per cm, my thought was "this is not even a conductor, let alone a superconductor". 0.2 Ohms/m is several orders of magnitude less conductive than most metals, and solidly in the semiconductor range.
- rubberpoliceman 3y agoResistivity is measured in ohms * meter, so this may be a unit conversion issue…
- moffkalast 3y agoRight? That's what's not clear to me either. If they got readings for superconductivity and Cu2S impurities were the cause then fantastic, Cu2S is the room temperature superconductor? Just get a load of that instead then. Or perhaps the way they measured the whole experiment was completely inane from the start if a simple conductor passes with flying colours. With that and them presenting ferromagnetism as the Messner effect makes me kind of question the competence of the entire analysis.
