I always figured SETI should be listening for neutrinos. Perhaps that's how aliens communicate?
What would it take to make this a practical method of communication e.g., have a reciever and transmitter in your phone? Would a super dense material work to capture them?
- scotty79 17y agoIn my opinion that's exactly why SETI has not detected any signal. There is a very low probability that two civilizations will be using radio waves for few exactly same centuries (even taking into account birthday paradox). Civilizations just few hundreds years more advanced than us probably routinely use cheap neutrino based communication channels. Sadly even if we can detect them they will be probably multiplexed, compressed and encrypted so much that without proper (impossible to guess) algorithms they will be indistinguishable from background noise. Looking for radio waves in space and sending them is almost as dumb as making big fire to create huge smoke signals for aliens and using looking glass to spot same kind of messages from aliens in the sky.
