Steve.
Thanks. I actually hit entanglement & superposition head on. but didn't dwell; Superposition is REAL, as the experiment confirms, but not what we expect. It's Maxwell's 'curl' with in inverse distribution to linear 'up/down', so NOT 'singlet' states!
'Entanglement' only needs to be retained parallel polar axes of the pairs. A,B 'measure' with rotatable field electrons; so each output is actually either 'SAME' or 'OPPOSITE' at some amplitudes. Think hard; non-locality is then NOT REQUIRED!
The only thing I've found at all limited about "classical intuition of space and time" is my ability to get it's logic across to those with different beliefs embedded or their own focussed viewpoint. SR was fully logically resolved in past (top 10) essays with the discrete (space/'time') field model (DFM) of nested spaces defined by relative motion and bounded by 2-fluid plasma interaction. i.e. your 'action' concept is indeed at it's heart.
Just identify what parts you don't recall resolved in the DFM and I'll run though it again. Not sure we can now access long posts, (yours?) so I'll stop here.
Best, Peter
