There are two
obvious solutions to Fermi´s paradox, and the reason why the matter hasn´t been
put to rest is simply that both answers are intolerable to Modern Man and his
belief in Eternal Progress, or rather a very specific view of Eternal Progress.
The first
obvious answer is the Rare Earth hypothesis. We really are alone, and we are
alone *not* because all civilizations go through a human-like history and
eventually destroy themselves in a human-like nuclear war (a typical 1970´s
anthropocentric conceit), but because multi-cellular life, or perhaps life as
such, only emerged once in the entire universe – here on the third rock from
the Sun. I´m not sure why this scenario is so intolerable to so many. Asimov
has it, and in his novels, humans eventually conquer the entire galaxy because
of it. I mean, there is no one to stop us! It´s almost as if the believers in
eternal progress want there to be advanced alien civilizations as a kind of
guarantee that we will once reach that stage, too. And a secret wish to fall
down and worship the aliens…?
The second
obvious answer is that the universe is *teeming* with life, including advanced
life, yes, including advanced intelligent life…but most of it is unable to or
even uninterested in developing our kind of advanced technology, let alone fly
around in space. (If you believe in the supernatural, you could even argue that
most life is clever enough to avoid this shitty universe, much preferring the
astral delights of some spirit-dimension.) Humans aren´t the only intelligent
species on Earth. What about chimpanzees, whales, ravens, or even octopi? Let´s
assume whales or octopi evolve for another 100 million years or so. What makes
us think they can´t become smarter? And why must this necessarily entail
leaving the sea, becoming bipedal and have opposable thumbs? “Because that is
the only way we can create a civilization”. No, it isn´t. What makes us think
the only way to create a civilization is the human way? What makes us think a
species with whale-derived intelligence would want to make the things humans
are making? Come to think of it, even creatures driven by pure instinct can
create something eerily resembling a civilization. Yes, I´m thinking of ants,
which did it millions of years before humans even existed.
And that´s
just one planet…
Imagine
what weird and wonderful creatures could evolve at other planets. Once again:
what makes us think they would be interested in communicating with other star
systems (or conquering them), rather than studying the notochord, the
immortality of the common cockchafer, or what have you. If they evolved
differently from us, they might not even *need* to create a high technology
civilization that emits radio waves. That´s something we have to do because we
(or many of us, at any rate) wouldn´t survive without one. Other species might
not need this kind of jerry-rigged contraption.
Believers
in the very specific kind of progress which entails going to the stars can come
up with some pretty bizarre scenarios “solving” Fermi´s paradox. Thus, one
prominent atheist (who is otherwise a very smart guy) claims that the aliens
must be hiding in the empty space in between star systems (that´s why we can´t
see them) constantly hooked up to a virtual reality more interesting than our
galaxy (that´s why they don´t bother with humans). Analyzing the Bayesian
probability for this might be interesting, even apart from the fact that it
sounds almost religious…

Seven solutions to Fermi´s paradox
Den första teorin fyller mig med olust - tydligen är inte mina känslor för Gud så varma att jag riktigt gillar idén om att vi är ensamma med Gud i ett helt universum.
ReplyDeleteMen den kan vara sann. Så länge ingen kommit på någon bra förklaring till att en "organisk" molekyl kan samarbeta med andra dito och bilda en cell...
Den andra är jag mer tveksam till. Det finns å andra sidan inget som säger att vi lätt skulle kunna upptäcka lokal radiokommunikation på Andromedagalaxen - för att inte tala om galaxer som ligger miljarder ljusår bort.
De kan ju också kommunicera på något sätt som vi ännu inte upptäckt.
Sedan har vi förstås ´Oumuamua - och KIC 8462852...
Ja, det stämmer. Det kan ju vara så att samma vetenskapsmän som yrar om Fermis paradox och vill hitta aliens får kalla fötter när något som faktiskt liknar aliens visar sig! Var inte KIC mindre kontroversiellt än Oumuamua? För att Oumuamua var närmare, kanske...?
ReplyDeleteJag tror annars att teori nummer två är den troligaste. Fast när jag är på mitt mest ovetenskapliga-teosofiska humör, så tror jag att kosmos kryllar av liv, fast från andra dimensioner. Det betyder att vi egentligen "ser" dem mest hela tiden...
"Rare Earth" i den version jag diskuterar är förresten sekulärt.
ReplyDeleteWhat´s wrong with nuclear Power, GMO´s and designer Babies? I don´t get it.
