Very much so.
First off, I'd like to make the random observation that my cat is an interferin' old baggage. Earlier, she crawled into my lap and started being desperately cute just when I was going to get up to fetch the books I wanted to work with. Now she's in bed trying to entice me to throw over hard work in favor of cuddles and a light read. This makes it harder to concentrate on the Really Big Questions.
I've started a science-reading spree. I'm currently near the end of Stephen Hawking's Universe, which was my run-up to A Brief History of Time. "The Universe Explained," my arse. I've realized that the general science survey written by the layman has lost its appeal for me. Especially since I keep getting this niggling sense that someone, somewhere, recently, said that the Universe didn't start with a singularity, which this author insists is so. Didn't some clever buggers find some evidence that the laws of physics actually didn't break down at the very beginning of the Big Bang? If any one of you knows, please do enlighten me.
The reason I'm feeling daunted isn't that I'm about to dive into the serious science reading. That's actually the easy part. The daunting comes from the fact that the cosmology I had worked out for my series isn't going to work, and I'm not sure yet just how I'll fix it. Rude questions keep arising that disturb the serenity I'd achieved. One aspect of said cosmology is that Eternals remember the previous Universe that gave rise to this one. How the hell could they? I'm sure there's a way to make that work, but damned if I see how just now.
There's also the fact of the Eternals themselves. I'm going to have to completely remake them. Again. They're natural beings. They need to come across as such. I'm having some interesting thoughts regarding them, but anything more concrete will have to wait until I've caught up with more recent research into quantum mechanics, chaos theory, and a few other aspects of hard science. Any suggestions you all have as to recent books on same would be very much appreciated.
This doesn't even get into the difficulties I'm still having with completely natural souls. There are some aspects of these stories that absolutely depend on the idea that an identity can survive death and rebirth, that it's even possible in the first place. And I don't see any reason to give that up just because I've decided that taking the soul as a given is ridiculous.
And that's just an infintesimal selection of the items currently heaping my plate. Add to this the fact I want to have the major work done by summer, because I plan to begin writing the first book in the series in earnest in the fall. That seems like a lot of time now, but...
At least the end result will be a better story. Or so I keep telling myself.
