I never said they should actually explain em, just that almost all sci-fi shows have them. Artificial gravity is a far worse offender, though you could sort of generate it through spinning, but most shows don't go that route,I think Gundam does, but it's unrealistic in that the sections spinning are too small, there'd be too big a difference between your feet and your head and you'd probably black out, that said Gundam has inertial dampeners too.
Star Trek is one of the worst offenders, when they accelerate to warp speed all the crew members should be splattered against the walls, yet a small hit from a torpedo causes everyone to fall over
