I'm sure this has been determined but I was wondering. In the Next Generation the ship has nice big windows in places like the captain's quarters and Troi's and Riker's quarters. But what about the windows that are on the underside of the ship? Does the gravity change on those decks so that the windows are still in the same place in relation to the room as shown in the above mentioned places? I can picture it either way, but for some reason the gravity changing is an annoying concept.
