Best Viewed with IE or Opera. Sorry, Firefox works, but loses some sidebar layout,
'my profile' and other stuff... Anybody with a fix, please leave a comment. Many thanks in advance.

That said, if you must use Firefox (and I don't blame you, it's become my browser of choice, too)
...get the "IE Tab" extension. This allows you to view problem pages with the IE rendering engine. Very cool!

The Space Review: The economic alien - by Gregory Anderson

Speculating about what an alien race might believe, think, or do has a definite fascination. Of course, it is nearly pure speculation; we simply don’t know enough about intelligence in the universe yet to reach even any tentative conclusions. It’s also important to remember that speculation is human speculation, and may not, therefore, have anything at all to do with the thought patterns of an intelligent species that evolved along its own path.
With that disclaimer firmly in mind, let’s look at the “Park Hypothesis” as put forth by Michael Huang in a recent TSR article. (See “The Park hypothesis”, The Space Review, May 30, 2006) Of course it’s possible another race would choose not to develop spaceflight. Human spaceflight over the long term is not yet guaranteed. However, as Mr. Huang points out, those civilizations that limit themselves to one planet will not last indefinitely. We should also note that not every civilization will develop high technology. For those that do not, even though the species might have the necessary intelligence, the question of whether to develop spaceflight will never come up.
Much of the SETI community tend to assume the only reason any civilization would develop space technology is to do scientific research. At some point, however, a technological civilization confined to one planet will likely be driven to look into space for energy, resources, new manufacturing opportunities, and more. 
In essence, then, The Park Hypothesis is only applicable to civilizations that have developed a technological base capable of supporting spaceflight. How likely is it that a civilization would go so far technologically, and decide to go no further? We don’t know. Speculating, however, we can fairly surmise that a technological base able to throw robots into space, for example, will also have begun to transform society. Production of industry will have reached a formidable level. The material wealth of the society may have begun an historic boom. Science will have begun to ask more interesting, more profound questions than ever before. Advanced robotic probes imply powerful, tiny computers, which would open an array of possibilities. The quality of medical care might well be on the rise. Would a society in that situation decide to push no further?
