A muon experiment proved their connection ignores whether measurement or decay came first.
Abstract

The role of temporal ordering in experiments with entangled unstable particles is examined, using the example of μ+ and μ- pairs produced in a maximally entangled spin state. Correlations between the measurement of the μ- spin (experimenter Alice) and the detection of μ+ decay products (experimenter Bob) are analyzed. It is established that correlations are preserved regardless of whether Bob's muon decays before or after Alice's spin measurement. The fact that the same empirical data allows different interpretations depending on the observer's frame of reference is discussed. The results support the view that the Copenhagen interpretation of measurement is a mathematical tool, not a literal description of physical reality.

Two inseparable halves of a single entity—that's how muons are born, linked by a shared property. If one half 'looks' up, the other instantly looks down. This connection, described by the Standard Model, doesn't weaken even when one particle vanishes. The survivor immediately reveals what the lost one was like. More importantly, this correlation ignores temporal order: observers may argue which happened first, but the outcome stays the same. The reason is the constancy of the speed of light, which blurs 'before' and 'after'. This fits with the philosophy of Niels Bohr and Werner Heisenberg: measurements don't uncover objective reality; they merely provide a convenient language for calculations. And here's a twist: these ephemeral particles reach us from the upper atmosphere only because time slows down for them at near-light speed—otherwise they'd decay long before meeting our detectors.

🎯 Muons are born when cosmic rays bombard the atmosphere. Every second, hundreds of these invisible and harmless particles pass through your body.

🎬 Like in the movie 'Tenet', where time flows in opposite directions, here observers can't agree on chronology—and physics doesn't break down.
