You know, I think you have to worry more about the average reader than the expert. There's no way you're going to be able to include all the data the expert has spent years learning. As long as the reader doesn't say 'yeah, right' in derision, I think you're good to go.

Reading fiction always requires the reader to suspend their disbelief to a certain extent, and hey, even experts like to just kick back and enjoy the story sometimes. ;)

I know what you mean about wanting to run away and hide in another fandom, though. I do that after I've posted my big bang story usually. *g*
