I know this is probably a common topic. For me, I’m not sure if it’s a “trope” or just totally misinformed writing, but it’s how many authors approach alcoholism. Some examples are Girl on the Train and The House Across the Lake, among HUNDREDS. If anyone else here has struggled with alcoholism, you know it’s not just "i woke up after downing an entire bottle of whiskey but was able to shower, down a cup of coffee, and solve a murder. "
Not so much of a trope, but misrepresenting simple physics.
Especially everything that has to do with rockets and orbital mechanics.
I get it, Star Trek and Starwars are science fantasy with their own rules about physics. But at least their are consistent. That’s okay.
However there are far to many books which claim within thier stories to adhere to real physics just to then “drop landing pots from the ship in orbit” which fall straight down without any force applied.
Or everyones favourite: the satellite which fires up its engines to reposition itself in the sky.
