In Swiss Alps frame, but it doesn't really matter, as the relative speed of the detectors were pretty nonrelativistic: 100 m/s - "Ferrari may do it!" (Gisin's comment)In which reference frame is the 5 ps measured?
One more great reading (quite easy, even for non-physicists!) on this thread's topic:
David Mermin, "Is the moon there when nobody looks? Reality and the quantum theory", PHYSICS TODAY / APRIL 1985 PAG. 38-47,
“Anybody who’s not bothered by Bell’s theorem has to have rocks in his head.”
To this moderate point of view I would only add the observation that contemporary physicists come in two varieties.
Type 1 physicists are bothered by EPR and Bell’s theorem.
Type 2 (the majority) are not, but one has to distinguish two subvarieties.
Type 2a physicists explain why they are not bothered. Their explanations tend either to miss the point entirely (like Born’s to Einstein) or to contain physical assertions that can be shown to be false.
Type 2b are not bothered and refuse to explain why. Their position is unassailable. (There is a variant of type 2b who say that Bohr straightened out the whole business, but refuse to explain how.)
If you don't want to be of type 2b - you must read it!
