At right-angles to our little

Waking world,

Dimensionless dancers,

Plying your dervish trade

In the shadowed

Lightless reaches of the

Miniscule.

The windows and doors here

So slight as to bar

The photon’s behemoth girth.

It is good to find

Your priests so pious,

Making their peace

At last with the Gravity Lords.

Bringing your realms to

A solid banker’s dozen

Bought you

Needed room to wiggle,

To say nothing of resolving your

Embarrassment of riches;

Exchanging your

Clumsy and vulgar pantheon

For a majestic,

And singular divinity.

King of the Gods

 

A bloody stain amid pastel bands,

A grave wound for the king of the gods.

A murderous eye, gazing in rage

Across vast and icy distances;

Both unblinking and unforgiving.

Lord of all storms, raging for ages,

Anger eternally fed by winds

Which race untroubled, unimpeded

By mountain, forest or tugging tide.

H

 

Take the humble hydrogen atom:

The smeared orbit of its lone sentry

Making a shell of the nothingness;

Weaving solids out of illusion.

First-born child of Mother Night, so

Ready to sacrifice itself that

It might purchase the photon’s freedom,

Emboldening the capricious sprite

To brave the void in search of an eye.

The Dragon

 

A Dragon dwells in the heart of the wood,

Destroyer of worlds and eater of suns.

The monarchs dancing across the skies

And the noble lords that follow;

The things which slither, the things that stride,

The things that swim and the things that fly:

Cloud and star, the light of reason,

All the atmosphere of heaven

Adorns the Great Wyrm’s table.

Is SETI a Waste of Time?

RtelThe SETI program, the Search for Extra-Terrestrial Intelligence, started back in 1960 with astronomer Frank Drake from Cornell University, who used a 26-meter radio-telescope to examine the Tau Ceti and Epsilon Eridani systems.  No luck.  Today, SETI projects survey the sky for transmissions from distant civilizations.  The soviets took an early interest in the 1960’s and the U.S. contributed money early on, but now it is funded privately.

My question is this:  Is SETI wasting its time and resources in this endeavor.  I am NOT suggesting they be stopped from perusing their goals however they wish.  It is a privately funded program that can and should do what it honestly feels is best to accomplish its mission.  But is it truly realistic to think this has any meaningful chance of success?

100,000 light years side to side; 200,000,000,000+ stars.

100,000 light years side to side; 200,000,000,000+ stars.

From what I have read on the subject, our TV and radio transmissions, which travel out in an expanding shell away from our planet, will be so defuse within two lightyears that they will completely disappear into the cosmic background radiation and be utterly invisible to anyone they might encounter.  That’s not even half-way to our nearest solar neighbor, the triple Alpha Centauri system.

A radio transmission, to reach between star systems, would have to be of incredible power and restricted to an very narrow beam to have any hope of detection.  Even if thousands of other civilizations have attempted aiming such a transmission directly at us, the chances of our being in the right place at the right time to catch it seem astronomically small; quite literally so in fact.

Radio simply isn’t a viable technology for communicating across these kinds of distances.  You might as well roll up a piece of parchment and tie it to a balloon.  Remember the old story about the ancient Chinese astronomer who tied rockets to a sedan chair to go to the moon?  He had a general concept of what to do, but no real appreciation of the technical problems involved in achieving it.  Any advanced, spacefaring civilization has either found a radically different technology for disseminating information across the void, or else that information travels only as fast as the ships that carry it.

Also, though life may well be as common as liquid water, I suspect that a biosphere as complex as the Earth’s is likely to be incredibly rare.  Think about it, any number of fantastically unlikely things had to happen for our homeworld to become the hothouse of life that it is.

The Earth was unspeakably lucky.  It grows-up in a stable planisphere, survives massive bombardment and the collisions of the early solar system.  One glancing blow knocks off a nice piece to create a stabilizing moon.  It has lots of big jovians in the outer orbits to gobble the comets up.

Protoplanetary-disk

I would wager that most worlds where life develops it I bet it never makes it far on.  Of those where it does, few will produce higher animals.  Of those which manage that, how many will produce biosystems as extravagant as our own?  Or an animal that will build tools and eventually leave its nest to spread life elsewhere.  Think about the number of both sperm and eggs that never get to join and create a new animal.  How many offspring most animals have because most won’t survive” Reverse attrition seems to the universe’s M.O; fewer and fewer each step; a tiny drop from one ocean, divided again and again.

Going by this, admittedly assumed trend, it also seems likely that few sentient creatures develop, fewer still will survive long once they do.  Doubtless many will kill themselves off with technology, as we may well do, or because they never leave their homes before some comet shows up and wastes their sorry asses.  Or whatever they’ve got.
