Yes. Theoretical Physics one to five, in five I had a One Point Zero. You don't really get paradoxes out of FTL-comms. I left most things out. Time dilation and space contraction for example. But the core that there wouldn't be any paradoxes if we could teleport FTL stands. The Light-Sound Analogon is not something I would present to any professional... because it leaves a LOT of things out.
