The Cold Edge of Forever, I: Equations
I want to write about Star Trek. Specifically, about the episode “The City on the Edge of Forever.” But I’m not going to do that right now. I’ll get there, but I’m going to start off by writing about a well-known prose sf story that to me parallels “City” in some interesting ways. Then, in my next post, I’ll go on to write about the Trek episode and make a fuller comparison (edit to add: time having passed, you can find the post here). First up, though: “The Cold Equations.”
“The Cold Equations” was written in 1954 by Tom Godwin for editor John W. Campbell and published in Astounding. Some, including writers Kurt Busiek and Lawrence Watt-Evans, have stated that the story was largely borrowed from an EC Comics short story by Al Feldstein with art by Wally Wood, “A Weighty Decision,” itself perhaps copied from an E.C. Tubb story (“Precedent”). At any rate, Godwin’s tale is well-known, having been adapted for the screen and frequently anthologised; I read it in The Road to Science Fiction 3: From Heinlein to Here.
A man, Barton, piloting a small spaceship carrying medicine to an isolated colony, discovers an eighteen-year-old stowaway, Marilyn, who wanted to see her brother on the colony world. But Marilyn, from Earth, doesn’t understand the way things work out on the frontier of space: the ship had exactly as much fuel as it needed to get to the planet — before Marilyn’s unexpected weight was added. With Marilyn, it won’t be able to land safely. For the people on the colony world to live, she has to be ejected from the ship. Barton frantically tries to find some way out, some way to keep her alive, but cannot; and so, willingly, she goes into the airlock, and dies out in the void of space. Physics and mass and momentum cannot be argued with, the story tells us; the cold equations must balance.
