In reply to the discussion: Bill Nye's Answer to the Fermi Paradox [View all]LongTomH
(8,636 posts)17. If we, as a species, continue to evolve, then it will be our evolutionary successors.
Some relevant quotes:
From Arthur C. Clark: "They will have time enough, in those endless aeons, to attempt all things, and to gather all knowledge no Gods imagined by our minds have ever possessed the powers they will command But for all that, they may envy us, basking in the bright afterglow of Creation; for we knew the Universe when it was young."
"If man survives for as long as the least successful of the dinosaurs, those creatures whom we often deride as nature's failures, then we may be certain of this: for all but a vanishingly brief instant near the dawn of history, the word 'ship' will mean spaceship.'
Frank. J. Tipler: "If the human species, or indeed any part of the biosphere, is to continue to survive, it must eventually leave the Earth and colonize space. For the simple fact of the matter is, the planet Earth is doomed Let us follow many environmentalists and regard the Earth as Gaia, the mother of all life (which indeed she is). Gaia, like all mothers, is not immortal. She is going to die. But her line of descent might be immortal . Gaia's children might never die out--provided they move into space. The Earth should be regarded as the womb of life, but one cannot remain in the womb forever."
Robert Shapiro, Planetary Dreams: "Earth has provided a stable platform for the evolution of life over 4 billion years. But that lease is limited; we know for sure that it will expire after a few billion more . If we are wise, we will have furnished our new apartments long before that time."
Tom Wolfe: "The purpose of the space program is not to maintain superiority in space but to build a bridge to the stars before the sun dies. Homo loquaz (man speaking) or Homo sapiens (rational man) is the only thoughtful creature in the universe, so far as we know. If he doesn't build himself that bridge to escape across, all is lost."
Ray Bradbury: "We are beholden to give back to the Universe . If we make landfall on another star system, we become immortal."

Not as simple as just tuning to the specific frequency, but to be able to decode the information.

The first problem is that this is not so much a paradox as a question...

Tight beam communications, like lasers or masers, are more efficient. Broadcast is wasteful.

That doesn't seem to me to be a paradox at all considering the vastness and distances of space.

The sheer size of the Universe makes it very difficult to receive signals from other civilizations.
