Imagine the following:
You have a lightwave controller (A), which controls a light transmitter (B),
and which is connected to a light receiver (C). You have a similiar
configuration on the far end of the "tunnel" - let's say controller (D),
transmitter (E), and receiver (F).
See diagram at http://enablia.dynip.com/public/unreal.gif
In a particular experiment, I program A to send a signal through B which is
recieved by F. I also program D to, at the moment it recieves a signal
through F, send a signal to C (via E). I then program A to abort the
transmission through B if it recieves a signal through C. Assume that
controller to peripheral communication costs 0 time. Let's also assume that
data processing and code execution costs 0 time. (I'm asking for some
imagination here!).
So, A tells B to send a FTL signal to F. D, upon recieving this signal,
tells E to send a FTL signal to C. A, upon receiving this signal (via C),
aborts the original transmission WHICH HAS ALREADY TAKEN PLACE. Paradox
anyone?
