    Why would it need to? Imagine that the ship accelerates at some rate a. That causes crew to accelerate at -a relative to the ship, which causes problems when they hit a wall. Modify gravity inside to be g = a. Now crew is free falling in the same direction as the ship. Now, just modify it a bit more so that you also have equivalent of Earth's gravity acting in the "down" direction of the ship, and you have the crew walking about while the ship does whatever crazy maneuvers that it does.

    Looks familiar?

      Or if you can maintain a steady acceleration of g, simply construct the ship as a tower block with an engine at the bottom. In such a design you only really need to max the acceleration to a safe gravitational pull.

        In the real world, yes that is presumably how we would build a ship.

        In Stargate, where they have artificial gravity and a reason to accelerate well beyond g (e.g., combat maneuvers, possibly entering hyperspace, etc.) as well as protracted periods where they would not accelerate (hyperspace, orbit, etc.), they would be using the method K^2 described.

          stargate ships look cooler this way.

            ...maybe in your opinion.

            Personally, I find some of the designs over at Atomic Rocket really cool.

              Coolness is overrated. Practicality is much more important. The lunar lander was ugly but damn good at its job.
