This thread is nuts. I didn't know people actually put that much science into their stories. I haven't gotten the chance to do too much of that myself, but I do think science is a great tool to keep parts of your story grounded - which in turn, makes the fantastical parts more fantastical. that said, some things are more interesting when they're mysterious, so it might not be a good idea to try to answer any question any reader could possibly ask. it's a dope tool, but you gotta know where to use it.
if you wanna see a cool example of real-life science in fiction, check out Dr.Stone. it's essentially a shonen anime, but instead of superpowers, there's accurate real-life science, and it's awesome.
