Dave Dawkins (D. Harrigon)Where does your character's knowledge end?

@golgaloth For so many authors, the character's knowledge ends where the SF author doesn't want to explain how something works.
The SF main character seems to know everything about how spaceships and guns and whatever works to the exact degree that the author has considered it, despite the fact that most people have very little idea how their own cars work and could barely figure out a bicycle.
@FirefighterGeek Yes, which brings up the all important question of, "Why does this character know that?"
RS, Author, Novelist, Prosaist...which brings up the all important question of, "Why does this character know that?"
Gah! Bring that question home, why don't ya? I just had to look up a section from a prequel to confirm that my character doesn't know that. Worse, she would never have troubled herself with that minutia.
