Again you go back to something being entirely factual. He could have used "5 grams" instead of the original theory. It's his choice. It doesn't matter if its mathematically correct, it doesn't matter if he made a mistake on the original theory.
Yes, science fiction is based around science and real theories, but that still means nothing in a work of fiction. For example, the Star Trek universe is based around science that doesn't exist. The mathematical theories for a star ship traveling at light speed may be sound, but they are still a work of fiction.
I assume if you watched Back to the Future, the idea of the flux capacitor turning banana peels into fuel would make your brain explode from rage.
You simply need to get over this obsession for everything to be 100% factual.
