On Stars and Science Fiction

October 14th, 2008

Really interesting stuff on James Nicoll’s blog:

The facts are wrong
Gene Ward Smith asks what looks like a reasonable question on rec.arts.sf.written

The mass-luminosity relationship for main-sequence stars was known [during] all of the Golden Age, and hence it was [known] that all of those sfnal Rigellians and Denebians were nonsensical, Was this simply being ignored as so much was ignored, or had the news not reached most sci-fi authors?

The actual answer is probably “a bit of both”. Even today it is easy to find an SF author who apparently has no idea about the lifespans of high mass stars – Eric Brown comes to mind – but as someone points out, at least one TV show recommended using named stars in episodes and named stars are almost always high mass/short life stars.

One subthread rapidly turns into “Well, maybe the mass-luminousity relationship is wrong!” argument, which nicely encapsulates something in SF that I will call the SFnal Lysenkoist Tendency: when actual, tested science contradicts some detail in an SF story, attack the science.

Go over there for the discussion.   I find this question fascinating, too, and realize that before college-level astronomy I could have been guilty of this error.   Natural plug for Launch Pad, of course!   When I get next year’s guest instructor lined up the website will get an update with new dates and an application deadline (Feb. or March).   Anyway, you can go here — my online resources for writers using astronomy — to get my slides on stars among other things.

And it’s a pet peeve of mine, too, that I hate when people attack pretty good science just because they think it could be wrong even though they have little or no evidence to suggest it.   The big bang is an easy target this way, but is an incredibley well supported theory at this point, but I’ve come across quite a few people who reject it out of hand based on nothing.   James P. Hogan, for one, if I recall correctly.   He’s a smart guy and a capable writer, but seems to have jumped off the cliff of reason into the sea of credulity in recent years.   Thinking outside the box is a good thing, but not if that’s all you do all the time.

I think this heretical science phenomenon is interesting and worth more discussion, but perhaps more on a sociological level rather than a scientific one.
