Pretentious Planet

I finally sat down and watched The Privileged Planet (RealAudio) this evening. What a waste of an hour.

I'd already read the book, which is pretty feeble to begin with, but take a book with no data in it, dilute it and diffuse it into the low signal format of a television program which consists mainly of slow pans and zooms around computer-generated graphics of astronomical phenomena, and you've got a thin broth indeed. The extremely low information density in the program has me even more dismayed that anyone at the Smithsonian saw fit to approve this fluff in the first place—all I can imagine is that the reviewer must have passed out in the first five minutes from boredom, woke up during the closing credits, and gave it a pass rather than admit to having slept through it all.

For example, it dedicates an unconscionable amount of time to the miracle of galactic habitable zones: in the center of the galaxy, it's too dangerous, and at the edges, heavier elements are too thinly distributed, so we can only exist in narrow zones within the galaxy…and voilà! That's where we are! This is the level of sophistication of this program; I guess they assumed the fruity voice of narrator John Rhys-Davies and glitzy CGI would add a level of portentousness to the affair that would convince a few people that it is important.

They also add another Amazing Coincidence, that these conditions suitable for our kind of life are also ideal for astronomical observations. I would also like to point out that in a similar way, I'm in an ideal place. If I'd been born 100 miles below the surface of the earth, I'd be cooked and dead, and even if I were able to survive in such an environment, I'd have no hope of seeing the stars. If I'd been born 100 miles above the surface, I'd have quickly gasped and died of oxygen deprivation…and if I miraculously survived there, I would still lack the raw materials to make telescopes. My existence on this narrow band of the surface is also wonderfully fine-tuned. Why, if my mother had given birth to me just 10 feet above the ground, I would have popped out to have immediately fallen on my soft little head, splat. It is also hard to do astronomy with acute post-natal brain damage.

Imagine a whole hour of earnest creationist hand-waving of this nature, culminating in a complaint that all the good ol' scientists like Copernicus had theological motivations. Why, if only we brought god back into our science, maybe we could make some progress.

If you really want, you can follow that link up above and watch it yourself. I can't recommend it—even you are sympathetic to ID, on purely aesthetic grounds, it's boring—but I will recommend that you read this review of the book by William H. Jefferys, of the Department of Astronomy at the University of Texas at Austin. As you might expect, it is not a kind review.

Finally, I turn to Gonzalez and Richards's notion that our earth is uniquely designed for its inhabitants to do scientific exploration, and that the universe is similarly designed for us to do that scientific exploration. They point to a number of phenomena that have aided our scientific enterprise, such as the transparency of the earth's atmosphere, the fact that we have a moon that is just far enough from the earth to produce spectacular solar eclipses, and so on. Of all the arguments in the book, I find this the weakest. It puts the cart before the horse. For suppose it were not so; if we existed on another world very different from the earth, then we would surely be doing something. We would be doing whatever was possible for us to do under the circumstances in which we found ourselves. If we accepted the Whiggish reasoning of the authors, we would be just as justified in concluding that our planet -- and our universe, if we could see it in this alternative reality -- was designed so that we would do whatever we happened to be doing at the time or find interesting at the time (as diverse human cultures have always done). The authors could learn much by studying a little anthropology and a little history.

To summarize, the little that is new in this book isn't interesting, and what is old is just old-hat creationism in a new, modern-looking astronomical costume. It is the same old shell game. It's too bad that Guillermo Gonzalez (whom I know from his tenure as a postdoctoral fellow in the University of Texas's Astronomy Department) has allowed himself to be sucked in as an advocate for this ancient argument. The Argument from Design is 200 years old, if not older, and it has not improved with age. It hasn't resulted in any new knowledge in all of those years. Modern astronomy is constantly producing new knowledge and understanding of the universe. Guillermo is a promising young astrophysicist, and I hope that he doesn't throw away his career on such nonsense.

Too late! I'm putting his drivel on his Permanent Record.

The low point in the movie for me was when Rhys-Davies solemnly declared that Gonzalez and Richards "meticulously tested their ideas against the best scientific evidence", and then they cut to a talking head babbling about habitable zones. There was no evidence, no tests meticulous or otherwise, and even the ideas were moldy and stale. And this is the best the Discovery Institute can do? Geez. Can we keep ID out of the school on grounds of banality?

Gimli narrated it? Drat, my opinion of him just shot down a number of notches. Watching Lord of the Rings just won't be the same experience ever again.

It's all of a piece with his recent prominent role as an obnoxious apologist on that hack TV show, Revelations.

These "science" programs have to be narrated by someone with a British accent, don't you know.

It would be strange indeed if a species that evolved on a particular planet did not find that planet 'meralulously' well 'designed' so support their life form.

The astronomical observation thing is the most ridiculous amount of runny crap I've ever heard. Wow.

Our position is NOT, by any means, the best place for astronomical observations. By being in the plane of the galaxy, our view of the inner part of the milky way, including the core, is greatly obscured by dust and gas. Ever see the center of the galaxy in the night sky? Not unless you can see in wavelengths other than visible light.

The ideal place would probably be in some star system floating above the plane of the galaxy. The galactic halo, one of theMilky Way's dwarf galaxies, the large or small Magellanic Cloud, or in an outlaying star of a globular cluster.

I think it was Terry Pratchett who observed how convenient it is that the universe is arranged so that the sun comes up in the morning, just when people are ready to go out to work.

Yes, PZ, but you could still have gotten a job as an ID theorist!

In terms of safety, we'd be a lot better off danger wise if the sun had been ejected from the galaxy and was sailing serenely through intergalactic space. Galaxies are dangerous. They collide, the intersteller dust slams into its counterpart at several hundred klicks heating it to incandescence in many cases, the collisions light up the black holes in the center in a Quasar like burst of activity that probably isn't much fun to be anywhere near, and passing stars perturb the Oort Cloud sending hordes of comets careening into the inner system. You'd think a <i>really<i> privileged planet would be clear of all that or in a nice small, safe galaxy like The Magellanic Cloud[s].

#6: Kieran's quote is from Hogfather:

Wizards didn't go to bed early in any case...*

* Often they lived to a timescale to suit themselves. Many of the senior ones, of course, lived entirely in the past, but several were like the Professor of Anthropics, who had invented an entire temporal system based on the belief that all the other ones were a mere illusion.

Many people are aware of the Weak and Strong Anthropic Principles. The Weak One says, basically, that it was jolly amazing of the universe to be constructed in such a way that humans could evolve to a point where they make a living in, for example, universities, while the Strong One says that, on the contrary, the whole point of the universe was that humans should not only work in universities but also write for huge sums books with words like 'Cosmic' and 'Chaos' in the titles.** The UU Professor of Anthropics had developed the Special and Inevitable Anthropic Principle, which was that the entire reason for the existence of the universe was the eventual evolution of the UU Professor of Anthropics. But this was only a formal statement of the theory which absolutely everyone, with only some minor details of a 'Fill in name here' nature, secretly believes to be true.

** And they are correct. The universe clearly operates for the benefit of humanity. This can be readily seen from the convenient way the sun comes up in the morning, when people are ready to start the day.

So apparently God managed to park a privileged planet or two in just the right spot, but all the other planetary systems were doomed to radiation-bake in the galactic core or starve for heavy elements on the rim? Score one for Satan, I guess.



#27648: — 06/07  at  08:40 PM
"Transparency of our atmosphere??"
Is that why we have infrared telescopes in orbit? And ultraviolet telescopes, also in orbit? Gamma ray? X-ray? Need I continue?

That's pretty lame stuff, all right....



#27649: craig — 06/07  at  08:50 PM
History is just FULL of these amazing miracles. Like, the Donner Party was stranded where? That's right - DONNER LAKE! Sure, it was Truckee Lake at the time, but that just makes it even more amazing. They couldn't possibly have known!

That's nothing, there's more... you'll never guess who's buried in Grant's tomb!

You mean we were not placed on Earth to find the question to '42'?

It took them an entire hour to say that it's a miracle that everything is exactly the way it is because if it were any other way it would be different? I guess the movie wasn't intelligently designed.



#27655: — 06/07  at  09:16 PM
There is point that jumped out at me from watching this drivel, which was the claim that Earth's atmosphere is aptly suited for the vaguely defined notion of "complex life." If I remember my natural history correctly, was not the atmosphere of early Earth quite unlike what it is now? It is well verified that early photosynethetic life helped produce the relatively oxygen rich and carbon poor atmosphere that is celebrated in this movie. I am not sure where I would go with this, but I guess it would be that in a zealous attempt to how all of science points toward design, they ran right by numerous phenomena like origin of our moon or of our current atmosphere that would be far more informative then a lot of repition and hand waving. Hey who wouldn't like to learn about how it was God's plan to slam Prometheus into primeval Earth to forge the Moon, like an interstellar billiards game gone wrong?

Mark Twain twits teleology, asking Was the World Made for Man?
It takes a long time to prepare a world for man, such a thing is not done in a day. Some of the great scientists, carefully deciphering the evidences furnished by geology, have arrived at the conviction that our world is prodigiously old, and they may be right, but Lord Kelvin is not of their opinion. He takes a cautious, conservative view, in order to be on the safe side, and feels sure it is not so old as they think. As Lord Kelvin is the highest authority in science now living, I think we must yield to him and accept his view. He does not concede that the world is more than a hundred million years old. He believes it is that old, but not older. Lyell believed that our race was introduced into the world 31,000 years ago, Herbert Spencer makes it 32,000. Lord Kelvin agrees with Spencer.

Very well. According to Kelvin's figures it took 99,968,000 years to prepare the world for man, impatient as the Creator doubtless was to see him and admire him. But a large enterprise like this has to be conducted warily, painstakingly, logically. It was foreseen that man would have to have the oyster. Therefore the first preparation was made for the oyster. Very well, you cannot make an oyster out of whole cloth, you must make the oyster's ancestor first. This is not done in a day. You must make a vast variety of invertebrates, to start with -- belemnites, trilobites, jebusites, amalekites, and that sort of fry, and put them to soak in a primary sea, and wait and see what will happen. Some will be a disappointments - the belemnites, the ammonites and such; they will be failures, they will die out and become extinct, in the course of the 19,000,000 years covered by the experiment, but all is not lost, for the amalekites will fetch the home-stake; they will develop gradually into encrinites, and stalactites, and blatherskites, and one thing and another as the mighty ages creep on and the Archaean and the Cambrian Periods pile their lofty crags in the primordial seas, and at last the first grand stage in the preparation of the world for man stands completed, the Oyster is done. An oyster has hardly any more reasoning power than a scientist has; and so it is reason ably certain that this one jumped to the conclusion that the nineteen-million years was a preparation for him; but that would be just like an oyster, which is the most conceited animal there is, except man. And anyway, this one could not know, at that early date, that he was only an incident in a scheme, and that there was some more to the scheme, yet.

Rhys-Davies appeared on stage with Michael Medved at the Discovery Institute on what I think was Jan 19 of 2004. One way or another, he's in bed with them.

"Why, if my mother had given birth to me just 10 feet above the ground, I would have popped out to have immediately fallen on my soft little head, splat."

Similar evidence for ID may be found in the fact that when women give birth, the baby is not on fire. Not only would flaming infants have a markedly reduced chance of survival, the mother would stand a significantly increased risk of dying in childbirth. The mathematics behind this phenomenon also favor a design inference. Any object has only two possible states of being: on fire or not on fire. If random chance alone accounted for determining the state in which a given object exists, we would reasonably expect that the distribution of on fire vs. not on fire for any set to be 50/50. The fact that this distribution is not observed in babies (and is much closer to a 100/0 split in favor of not on fire) strongly suggests that this particular process has been intelligently designed by some unknown agent at an unknown point in the past.



#27672: — 06/08  at  12:05 AM
Once again, the IDers prove that the thing most threatening to them is the notion that humans are not, in fact, the center of the universe and are not necessarily specially privileged. Which puts them at the emotional age of about, what, three years old?



#27677: Pete — 06/08  at  01:40 AM
Sean, I'm sure William Dembski would appreciate the mathematical rigor you've brought to the problem.

Geral -- you want to use a player for Real media (see http://www.real.com).

Thanks everyone for watching the film so I don't have to.

The Earth was placed to find the question to "42," but we were placed on it because some planet wanted to get rid of all the accountants, hairdressers, marketers, and other useless people.



#27680: RPM — 06/08  at  04:41 AM
Maybe some folks at the DI saw a science documentary at some point in the near history and thought, "This stuff sounds really dry and boring." Then, when it came time for them to make their own movie, they decided to emulate the model they were familiar with. They could've made it scientifically interesting, but they couldn't distinguish the science in any science films they'd seen, so they had nothing to go with.
