There is a certain class of Space Opera that has what I call “Buck Rodgers Cosmology.” In these stories it is never quite certain what a planet is. You see sentences like “It was still morning on [planet].” Or perhaps “It’s summer on [planet], so dress accordingly.”
And of course we’re all familiar with the “jungle planet”, the “tropical paradise planet”, and the “snow planet”, all of which are entire planets with only one climate zone, and that climate is easily recognized as one of the many on our own rock. So even though we live and interact with a shining counterexample our entire lives, we all too often are presented with a planet that apparently has no poles. Or perhaps it’s in a multi-star system that somehow warms all parts of the globe evenly.
I call it Buck Rodgers Cosmology because early Buck Rodgers adventures joyfully embraced a vague idea of planets that didn’t even seem to be related to stars.
Recently I read some not-very-good-but-for-some-reason-I-read-it-anyway-so-maybe-it-had-a-certain-charm Space Opera, and while the author seemed to have a certain grasp of stars, planets, and whatnot, it seemed that most of the time the planets managed to avoid any of the consequences of being spherical.
While I was reading this thing, I rolled my eyes and moved on. I wonder if the writer knowingly embraced Buck Rodgers Cosmology. I wonder if he made a conscious decision to make planets so easily characterized in order to make destinations more like those in Earth-bound adventure stories. One planet is Hawaii, another planet is Switzerland, and another is Arizona. In fact, these stories are actually set on Earth, an Earth in disguise, at a time when it takes many days to reach Hawaii, and where the inhabitants of Hawaii have blue skin. They’re not space stories at all.
In the end, I decided Buck Rodgers Cosmology was no less valid than the whole Faster-Than-Light-Without-Relativity conceit. It’s a storytelling device, and if the reader is willing to embrace it, then we can all get along.
The story I mentioned above also had big space battles that led to giant spaceships “listing to port” when they were badly damaged. I am far less forgiving of that phrase. The writer is drawing a parallel with modern sailing ships, but sinking boats list because of gravity. There’s too much water coming in on one side, and gravity tips the boat to that side. No gravity in space. No listing. No “port” even, though that could be defined in some sort of ridiculous three-dimensional fleet coordinate system.
I have read a great deal of space opera where opposing fleets of spaceships are all in the same plane.
The thing is, there’s another phrase for a stricken ship that’s more accurate and just as poignant. Stricken naval ships list, stricken spaceships tumble. It’s that simple. And tumbling makes rescue all the more difficult.
So I’ll give you the Buck Rodgers Cosmology, but I won’t give you stupid fleet mechanics. The former provides a storytelling shorthand, the latter is just wrong.
