that each photon in light has a linked twin, what is done to one
happens to the other. So if you could somehow capture the twins and
separate them would allow signals to be applied to one and received
from the other.
Now how would you capture and hold a photon.

What you do is set up two identical communications channels and feed
their inputs with a single pulse, then measure the difference in
arrival times of the output pulses. The difference which exists will
be due to the fact that both channels aren't exactly identical, and
once that systematic delay difference is noted, the superluminal
signalling device (SSD) is introduced into one of the channels and the
measurement made again. Now, once the result of the measurement is
normalized by subtracting out the systematic delay, the delay
exhibited by the superluminal channel should be less than that
exhibited by the control channel. The measurement should be made many
times, of course, with the SSD moved back and forth between channels
to make sure whether or not the short delay follows the SSD.
I disagree. The experiment needs to have 2 way communications at a speed
faster than light. You have to send the signal from on location, have it
cause something at another and return a signal to the first. Without the
return trip the FLT could be an illusion.

Not if the measurement is done correctly. Consider:

| |
| +--|--+
| | A |
[PULSE GEN]--[SPLITTER] |SCOPE|
| | B |
| +--|--+
| |
+-->COM PATH 2-->[FIXED DELAY]--[EDGE DETECTOR]--+
Set up the system so the pulse generator is continuously putting out
pulses of a convenient width and PRF, and arrange the fixed delay time
so that with the scope trigger source set to A and the horizontal
speed set so that no more than one pulse is visible, the rising edge
of the received pulse will be seen at some convenient point to the
right of the start of the sweep. Now, if a working SSD is inserted
into COM path 1,:
+-->COM PATH 1-->[SSD]--[EDGE DETECTOR]<---------+

| +--|--+
| | A |
[PULSE GEN]--[SPLITTER] |SCOPE|
| | B |
| +--|--+
| |
+-->COM PATH 2-->[FIXED DELAY]--[EDGE DETECTOR]--+
the propagation time through COM path 1, by the pulse used to trigger
the scope, will be decreased and the rising edge of the pulse on the B
input will be seen to move to the right of the position it occupied on
the display when no SSD was fitted.
Of course, if long COM paths were desired, (say to the moon and back)
transponders could be installed on the moon at opposite points on the
face it always points at us and the experiment performed that way.
Matter of fact, I think that ESP is superluminal and that's part of an
experiment which could be performed to determine whether it exists
and, if it does, how fast it goes. Wanna hear about it?
