ET Will Phone Home Using Neutrinos, Not Photons

Posted by timothy on from the speak-and-spell-is-cross-particle-compatible dept.

KentuckyFC writes "Neutrinos are better than photons for communicating across the galaxy. That's the conclusion of a group of US astronomers who say that the galaxy is filled with photons that make communications channels noisy whereas neutrino comms would be relatively noise free. Photons are also easily scattered and the centre of the galaxy blocks them entirely. That means any civilisation advanced enough to have started to colonise the galaxy would have to rely on neutrino communications. And the astronomers reckon that the next generation of neutrino detectors should be sensitive enough to pick up ET's chatter."

    We'll learn precisely what kind of chemical product aliens use to enlarge their penis.

      1) Make a neutrino sniffer
      2) Reverse engineer alien penis enlargement chemical.
      3) Adapt it to Earthlings.
      3) PROFIT!

      For a person that quotes Hitchhiker's Guide in their sig, you've got an awfully pesimistic view on the comedic potential of the universe.

      If sexual reproduction is common, the penis is a likely solution. I know that might be difficult for the average slashdotter to grasp. Erm, so to speak.

    Can I assume they'll need galactic warrants for these cosmic wiretaps?

      No, because ET will be required by law to release his encryption method and keys.

      They won't need wire taps. They only have to catch a small fraction of the neutrinos in the stream, the rest will pass through the detector on their way to our criminal cohorts at centauri prime. Of course, the galactic coppers will have to be exactly in line with between us. Not a place i'd like to be. During a galactic gang war, all the relativistic projectiles will be flying along that trajectory! Serves 'em right for setting the speed limit at C.
