Hacked stars might broadcast alien signals

    If we received a message from an extraterrestrial civilization, would we necessarily realize it? SETI has long scanned the skies for evidence of alien transmissions, while others have proposed a hunt for physical artifacts sent by our distant neighbors. But neutrino physicists at the University of Hawaii have proposed yet another possibility: that humans have already received an extraterrestrial communication, and that we might find the message in our existing observations of the stars.

    I find it an interesting proposal actually

    forgive my total ignorance but would such a system not take ages to send messages given the speed of light?

    If this was a process that occured some tens or even hundreds of thousands of years ago, then the information will already have travelled the distance to us.

    Ok, but it wouldn't really be a good system for communicating in an efficient way, everything would be really slow.

    I guess aliens could state "we're here" and share some technological info...but they would either have evolved or just become extinct in the intervening period.

    I think these neutrino physicists are on the right track though, thinking of possibilities we wouldn't consider, I like this kind of thinking, we have an understandably earth centered view of things, imo the same could apply to our search for life.
