That's really interesting to me.

When a photon 'tunnels', the statistical chance of it being elsewhere changes instantaneously, but since it has moved, and the wave front of its previous statistical distribution had also moved at the speed of light, the change in statistical probability has to travel at double the speed of light.

if we had a line A-B-C-D-E, with the photon at C to start with, with an equal probability of being at A and E, then it tunnels to E.

If the probability distribution changes at the speed of light, then the probability of being at A is still high, so the photon could tunnel there (at twice the speed of light).

Maybe im stretching an analogy too far.

Yes it was what Einstein called "spooky action at-a-distance".

I don't believe it's possible for the wavefront to collapse faster than the speed of light, because information can't travel faster than the speed of light. But yet that's what the observations show. But to me, this is just more evidence of the hidden variable theory.
