  1. Re:Old? Can we truly define old for the universe? on The Fermi Paradox is Back · · Score: 1

    None of which, you'll not, transmitts with mega watts of power. These devices by nature, do NOT breach the atmosphere. They are low power. Yes, detectable. No, not intelligible. Probably looks like static and hash. SETI stuff.

  2. Old? Can we truly define old for the universe? on The Fermi Paradox is Back · · Score: 3, Interesting

    It behooves us to consider Fermi. The idea is indeed seductive.
    On the other hand, just because WE don't usually quite make one hundred years of consciousness, we assume all things told, that six BILLION is old, and Thirteen Billion is even older.

    One thing no one has pointed out yet. What if that is YOUNG? Vaunted as he was, Fermi didn't include that as a possibility. He either didn't see it, or discounted it. What if we're the FIRST major civilization to grow? Or, let's use our own development as a yardstick. It took us, what seventy five years? to begin putting the broadcast entertainment onto cable, and stop actually advertising our existence. It won't be much longer, and our planet will be nearly invisible.
    Now, if technology develops the same, no matter WHEN, but THAT, it would have taken a hundred years, roughly, for the civ to develop broadcasting, use it, and then, as we are doing, turn it inwards, and not waste power in exo-broadcasting.
    So, any star roughly a hundred light years out would be able to pick up our signals, but if their civ had gotten a start a thousand years before ours, well, then, we missed their shows by a millennium. Talk about the need for TIVO.

    My point is simple. We assume any civ out there is attempting to get our attention. If they developed like ours, even starting the same day, we won't see them at all, UNLESS they are at the right distance. Otherwise, we won't see their signals, as it already passed us by, or the leading edge hasn't hit us yet.

    We won't even go into the many different and varied methods we ourselves use to communicate that never beak the atmosphere, thus making them exo-undetectable. Fermi's assumption is a classic illustration of of assuming... You know, making an @ss out of you and me?
