Solving science puzzles … in space!
It occurred to me a while back that a lot of classic science fiction could be described this way:
A few characters encounter an almost unsolvable problem in space, and they're going to die. Fortunately, the author has embedded a scientific solution in the setup, and even more fortunately, the characters happen to come up with exactly that solution!
There's nothing wrong with that story template. When I was a kid, reading through my father's classic sf bookshelves, I ate it up. And I'm sure plenty of people still like it.
But these days, it just doesn't appeal to me very much.
