I also don't do physics, but do cute creatures! Why do Bats get so much hate!! This guy is adorbs~
He was so patient (or likely traumatized). Showed me his teeth once, and then I scooped him up and he went limp. Which was either "I give up. Go ahead and eat me." Or "I'm just a dead bat here. Nothing worth looking at. Move along.) Then he carefully folded his wings up as I put him in a box, and he didn't move for an hour. -_- I'm glad he wasn't hurt. My dog thinks all furry things are puppies.
As for other conversation, it's funny what we learn for the sake of creation. Not astrophysics, but I have become more informed about ballistics. And rules of some sports. And emergency procedures and chain of command – which was a required course for work, as was first aid and CPR, but it's useful in my writing.
When I was a teen, I tried writing a space opera. It was terrible. Worst cliches around. There was a "chosen one" being hunted by interdimensional assassins and everything. (Hollywood probably would have loved it. I abandoned it like a hundred other projects.)
