    More importantly, if you were on the boat, would anyone hear you scream?

      If you opened door 3 whilst on a treadmill, then the goat would sink and the boat would take off.

        But who would get the car?

          or in it maybe if it has already sunk before going into space?

          Depending on the relative positions of the boat and the water when it is exposed to the extremely cold temparatures, I would think the boat would retain the same relative position after freezing.

            wouldn't "on top" imply that the ice were below the boat?.....
            and if there was no gravity.... Shirley "Up" and "Down"/"Above" and "Below" would be somewhat meaningless.... ie Isn't it gravity "sucking" that defines "down" for us......

            Only asking!

              Depending on the temperature and pressure. At low enough pressure and high enough temperature (to overcome molecular forces), the water would be everywhere, like a cloud.

                What would hold all the water molecules together?
                Gravity
                You just hold me down so quietly
                You just pull me down to earth
                Let me grow into the depths of your infinity
                I can sense your presence in the vicinity...

                  Would take a loooong time to freeze a sea in space i reckon. I'd say by then, all the water would have drifted off all over the shop in icy clumps and the boat would be sea-less.

                  They should pack everyone on sickness benefits into the QE2 and try it.

                    Everything has some gravity.

                      In Star Trek physics Spaceship orientation is absolute, meaning ships are always the same way up. Except when one spaceship has been hit, in which case it will be at an angle or the other way up.
