The signalling would be the galactic equivalent of the internet. <snip> Seth Shostak of the SETI Institute in Mountain View, California, thinks it is a "nice suggestion". "But I'm inclined to think that positing the Cepheid scheme is like someone in Marconi's time predicting future radio broadcasters will use giant spark-gap transmitters to reach audiences in large cities," he says. "Better technology means higher efficiency, so using an entire star as the 'carrier' seems unlikely to me." [Quote Ends] ----- And for once I think Seth is telling a minimal truth, as dictated by logic: I.e all that ETs (or us) need is for two or more far-separated stations to focus their telescopes (with rather special mod/demodulator eqpt attached) on a star midway between them. We now know that a) stars produce billions of entangled photons every minute; and b) that an observer can `read' or indeed `fix' the state of a far-distant paired photon by examining the local paired version. A version of the `entanglement method' could be used to send a continuous galaxy-wide broadcast, or a slightly different version for one-to-one (coded) links. That method of `modulation' is somewhat similar in its results to spread spectrum modulation. That is, the modulated signal is virtually undetectable, appearing as low-level background noise. Only if you're running the pre-arranged pseudo-random code - like a metronome - can you retrieve and decode a signal from that `noise'. I think Seth is aware of most of that; maybe he just doesn't want the public to know. Cheers Ray D Listen to 'Strange Days...
