To explain the correlation in a Bell experiments three solution are considered :(adsbygoogle = window.adsbygoogle || []).push({});

1) faster than light communication

2) preexisting values are revealed at each measurement points

3) nonlocality applies

1) is ruled out by relativity

2) is ruled out by Bell's theorem

Remains nonlocality. But what does it mean ?

Is it that in relativity if we go at the speed of light then therr is no space anymore in that reference frame ? Namely if we look at the Lorentz transformation $$x'=\frac {x-vt}{\sqrt {-v^2/c^2}} $$ then v=c is singular.

If we imagine a photon sending a signal from A to B then in its frame all the space between A and B condensate into a single point at infinity since we divide by zero.

This would mean that along A and B in the frame of the phophoton there is no distance hence it were nonlocal and compatible with relativity ?
