There is much on the topic of superluminal transfer of information being forbidden by special relativity, however, in reading such articles they always quote the causality paradox, as a reason for preventing such transfer.

What I do not see, as I am no physicist, is how causality would be affected if, for arguments sake, a superluminal radio message at one end of the universe was instantaneously received at the opposite end. [i](Assuming for this thought experiment that there are definable edges which do not otherwise wrap such signals around at those edges)[/]

This is also something of a two-part question, as I understand it, it is theorised that two quantum-entangled photons can influence each other at, theoretically, any distance.  If this is so, then why isn't it reported how this would, by the definitions mentioned above, not affect causality, since presumably information is zapping between the two somehow, instantaneously.

I beg of any replies to be in the English language, as sadly I am no mathemetician, and I have terrible concerns that my answer would be in a series of formulae otherwise indecipherable to me. :-)
