Space ships in Star Wars frequently use energy weapons for combat. Given that Sir Isaac Newton is the deadliest SOAB in space, I was wondering if this also applies to the non-kinetic space weapons used in Star Wars. Do they have a maximum range after which the shot dissipates, or do they veer off into deep space and possibly hit some unlocky sod several millenia later?
