There are certain ideas that I find completely acceptable in the context of science-fiction, but completely looney in the context of actual science.

Take, for instance, Erich von Däniken’s premise that gods were really ancient alien astronauts. It’s an interesting idea, but it’s way out there in terms of science. It assumes that (a) myths are historically accurate, (b) aliens exist, and (c) low-tech humans couldn’t possibly have created things like Stonehenge, pyramids, giant stone heads, etc. Not to say it’s not possible that aliens visited the planet in the distant past—just that comparative mythology and architecture aren’t exactly compelling evidence.

On the other hand, I have no problem with the concept in science-fiction. It’s the basic premise of Stargate. The movie and early seasons of SG-1 focused on Egyptian mythology and technology, and in subsequent seasons of the show, just about every ancient legend has turned out to have an alien race behind it. It also figures into the backstory of Babylon 5, with the Vorlons having visited nearly every known race in ancient times, insinuating themselves into local religions and engineering telepaths over the course of centuries.

I was thinking about a discussion on last month’s Flash #226 and got to thinking about the way religion figures into mainstream comic books. Not the way religious characters are portrayed, but the way the fictional world works. I’m not familiar enough with Marvel (though I can make some guesses based on the presence of Thor), but DC seems to have an “anything goes” cosmology: current scientific theory coexists with the Christian God, Heaven and Hell, with gods and other supernatural beings from various mythologies—some of them made up, like the Lords of Order and Chaos—occupying their own corners of the universe.

That’s probably what you want for a long-term, open-ended shared universe, because it gives you the most opportunities for stories. Want to write about an alien race that lived billions of years ago, or evolved from cats? Check. Have a fallen angel join the Justice League? Check. Tie Wonder Woman’s origin directly to the Greek gods? Check. Use made-up alien gods to explain the Greco-Roman split? Check. Power up half your villains and a handful of heroes as they sell their souls to a devil? Check. Pit the spirit of God’s wrath against a 50,000-year-old immortal ex-caveman? Check. Send some characters to Heaven or Hell, but have others destined to be reincarnated over and over again? Check. Observe the hand of God at the moment of the big bang? Check.

There are a couple of limits. DC seems to avoid ascribing a particular religion or denomination to any of their A-list characters, probably so that readers can just assume it’s their own (kind of like setting a story in “Anytown, USA”). And they avoid direct portrayals of God or Jesus, probably for the same reason. Continue reading →

From the Astronomy Picture of the Day, it’s the remnants of a two-billion-year-old nuclear reactor discovered in 1972 in a mine in Oklo, Gabon.

Apparently in the old days there was enough uranium-235 in the Earth’s crust that, under the right conditions, nuclear fission could occur naturally. Over time the fuel was used up, and now uranium deposits are mostly 238U, so we don’t need to worry about any new nuclear reactors popping up without our help.

What’s really odd is that this reactor produced plutonium naturally. There’s still some there. Most periodic tables I’ve seen label plutonium as a synthetic element, so the idea of natural plutonium takes some getting used to.

Kind of like the idea of a natural nuclear reactor.
