Or, the Difficult Worldbuilding Compromises that Result when You Didn’t Design Everything at the Same Time.
It has been (entirely correctly) pointed out over on Google+ that this is not how wormholes, as we understand them today, would work.
(Because they’d work like this.)
This is one of those cases, though, where I end up invoking “firmish SF” – and one in which I’m trying hard to deprecate the term “wormhole”1 to refer to the kind of FTL there just to avoid confusion…
Having done my reading on said-hypothetically possible wormholes, I did my damnedest to use them properly. (Long-term readers of mine may, for example, remember some older references to wormholes as continuously existing Visser-type structures embedded in exotic matter frames, now quietly retconned out of canon – which indeed worked exactly as they should with regard to local conservation; having traversers’ mass and momentum added to the mouth they enter and subtracted from the mouth they exit.)
This would probably have worked a lot better for me if I’d not had an existing background/setting, because while I’ve rewritten a lot of things a lot of times to fit with hard-scientific plausibiity, after wrestling with it for a lengthy period – well, I came to the conclusion that while it offered me some very interesting options for how things would play out, there was pretty much no way I could reconcile it with what I had short of throwing out the setting and writing a new one from scratch. And, well, ouch.
So given the choice between that, badly mangling real science, or constructing some con-science to fit – in just this case, um, space magic? 🙂
1. Suggestions for alternative terminology gratefully accepted, since I really don’t want to keep calling these things wormholes when they don’t behave like wormholes. Especially since, arguably, there’s no reason that wormholes-which-are-wormholes couldn’t also exist there.
