Re. The Good, The Bad, and the Ugly
I had this discussion with some folks on the LHC forum; the upshot was that the Wow! signal just might have been the radio leakage from dropping out of FTL.
Assuming an Alcubierre-like hypertime drive which uses superdense rotating normal matter in front to locally accelerate the expansion of the Universe for propulsion.
It could be that a Gen 0 (ie Phoenix) FTL might generate a certain RF pulse signature but an entire fleet of ships dropping out would have to do so sequentially or bad things would occur.
