Hi! I’m currently building a hard sci-fi world and I was wondering about the idea of war. Because space is huge - really huge, and most ships probably won’t interact with each other for years or centuries. But if two space ships or fleets were to meet on a new stellar system and declare war to each other, what could this look like? What weapons could they use?
Have you ever tackled the subject in one of your worlds? Or do you know a piece of media which did this?
If kinetics are out of the picture, lasers are completely countered by mirrors.
Plus the intensity falloff is significant, especially over the distances space travel allows.
