When some guys go through the gate, how are they able to communicate with the rest of the crew that was left behind. It seems they can communicate in the real time.
Is it a blunder or is there a scientific (read: sci-fi) explanation to this? Do the electric waves travel though the gate or somehow they figured out how to speed them up beyond the speed of light? Perhaps it was explained in the movie?
I can almost understand how the robot (whatever they call it) can send the telemetry data when the gate is active.
There was an episode where the star ship got stuck in the gate. So half of it was demolecularized, but wasn't transmitted to the other side, because the gate only sends objects in one piece. Somehow it knows. A verification hash code?
What happens if you push your hand in and want to pull it back? Would you be able to or would it already be demolecularized? In other words, no changing your mind once you stuck your head in!
