Although entropy is my favorite physical concept, propulsion is a close second. It's not so much the lack of gravity that attracts me to space--it's the lack of friction. The closest approximation would be in the doldrums, the land underneath where all the air currents meet. There it's completely calm on the ground while above you is the collision of every breeze, gust, and torrent in the world.
