Quanta Magazine posted a 17 September talk with Jonathan Halliwell on decoherence as the path out of wave-like quantum motion into ordinary scale. It is an interview, not a new experiment. Strogatz and Levin host the Joy of Why episode. The stamp is 15:09 UTC.
Quanta Magazine posted on 17 September a talk with Jonathan Halliwell about decoherence taking matter out of wave-like quantum motion into ordinary large-scale physics. The magazine frames that as locating the classical edge. It is a physics interview, not a new lab result. Steven Strogatz and Janna Levin host the Joy of Why episode in which Halliwell speaks.[1]
The conversation is stamped 17 September 2026 at 15:09 UTC. No new measurement, sample or discovery is announced; the episode walks through an existing theoretical frame. On the same page Quanta Magazine says it is independent in its editing, with Simons Foundation backing noted on the page.[1]
A second independent publisher's own page confirming the same Halliwell interview was not found among Nature and Live Science headlines on 17 September 2026. The retained desk copy therefore treats Quanta Magazine as the sole news publisher for this conversation. Decoherence here is Halliwell's teaching term in that episode, not a newly measured constant. Nature and Live Science remaining silent on this interview is a ladder finding for this slot, not a judgement on Halliwell's prior papers.[1]
