[QUOTE="Umbran, post: 6255009, member: 177"] Interstellar modes of communication are governed more by physics than by the form of life. There are only so many ways to get a signal between the stars. That latter one of those is simple - the cosmological red-shift doesn't happen within gravitationally bound systems. The galaxy is not expanding so that it would red-shift. Point-to-point laser communication could be done, I suppose. It would require you know where the target is - so it is only good for talking to your own people. The Higgs bosons would be a lousy vehicle for interstellar communication - they have a a half life of almost nothing. Neutrinos, fine. Not Higgs. And, well, if the only way you have to communicate between the stars is for a star to blow up... there's a problem. You'd ave to travel to that dying star to send your message, and you could only send it when the star is dying. So, why didn't you just travel to the place you wanted to talk to, when you actually wanted to talk? And, by the way, our radiotelescopes would catch the latter, and SETI spends a lot of effort to find non-randomness in radio signals from space. This is a way we could likely detect. [/QUOTE]
