Possibly the question should be re-phrased allowing for a more detailed scientific analysis..........Comment

Radiation, convection and conduction are all methods of heat transfer.
I think the water would boil away if not contained by some form of pressure vessel.The close proximity of the letters 'G' and 'T' are the reason I'll never again send an important email and end it with "Regards" ....Comment

I think MTC is right, the boat would sit on a sphere of ice.
But... If it got close enough to a star it would sink through the melting water.Science isn't about why, it's about why not. You ask: why is so much of our science dangerous? I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave JohnsonComment

Also the boat would need to be denser than the water for it to sink to the middle, buoyancy would have no effect.Last edited by gingerjedi; 17 June 2009, 12:50.Science isn't about why, it's about why not.

Assuming that "the laws of physics" did still exist perhaps you could propose how the "sea" and the "boat" were transported to this "Zero Gravity Place" (which still has gravity)Comment
