I don't want to knock Mr Einstein (and perhaps someone who knows more about quantum physics than me can help me out here) but, surely, 2 photons of light, emitted from opposite sides of the Sun, will have a speed *relative to each other* of twice the speed of light...? So, 'poof' goes that theory...No?

IT IS ALL ENTANGLED EVEN SOUND CAN GO FASTER THAN LIGHT http://blog.hasslberger.com/docs/THE_TIME_CONTINUM-3.pdf

Previous commenter would be right (about two photons) IF time and space were Euclidean. It was Einstein greatest intuitive leap to consider that might not be true. Space-time is not Euclidean and you cannot simply add two velocities together. Besides that, it's not quite what Einstein said -- "nothing can go faster than light" is a simplification. Easy example: take your laser pointer and wave it at the moon. The (weak!) spot of light on the moon's surface easily exceeds the speed of light .Better to say "nothing can deliver information or energy faster than light would".

It seems the effects of quantum entanglement do not violate relativity if one pictures the entangled photons as at opposite ends of a 1200 kilometer piece of twine. Pulling on one end of the twine would immediately be felt at the other end, regardless of distance. Travel time: zero.

@Martin I don't pretend to be much knowledgeable about this either but here are 2 links that describe why the relative velocity of any 2 entities (photons) can only be at most c = speed of light. In essence the bottom line is that Vrelative = V1 - V2 is only approximately correct when neither of the velocities are close to c. There is thus a different formula that describes how relative velocity functions in the special relativity model.
