Rapaire,

I am afraid you misunderstand the nature of entanglement. As I understand it it is not physical linkage in the sense you mean and it does not preclude photons moving great distances from each other without any diminution to the entanglement. Entanglement is not inversely proportional to the square of distance. This is important because it says something about the nature of space.

Entanglement is permanent and instantaneous -- that is when one of the pair is determined to have turned left the other one will predictably have turned left also (or perhaps it is right), over 90% of the time.

This is more like love than it is like gravity -- the link is ineluctable regardless of distance, response is instantaneous, confidence is high, and life is glorious.
