The Physics of Space Gardens

Space Gardens


“It could only happen in space,” NASA's interplanetary gardeners explain. “A tiny bubble of air hangs suspended inside a droplet of water. The droplet rests in the cup of a delicate green leaf, yet the stalk doesn't bend at all.”

On gravity-laden Earth, however, “[t]he air bubble, lighter than water, would race upward to burst through the surface of the droplet. Meanwhile, the leaf would be busy tipping the heavy water onto the floor below. Everything would be in motion, the picture a blur.”

As it is, the photo can be upside down or even sideways and still get the same photographic result.

So if and when space gardens have outgrown their primary role as agriculture or a sort of organic HVAC in the early stages of space colonization, and our intrepid colonists attempt a more recreational approach, well, how would they design it when one can float? When a wall is a floor is a ceiling is a floor is a wall in zero gravity. (Except when it's got a door.) A simple gesture like craning your neck up at a tree may no longer be necessary when it's a simple skip and a jump to the canopy. A truly three-dimensional space, not just up to 10 feet off the ground.

And fountains, infamous for their gravity-defying acts, may simply be a billion-dollar lava lamp, which would be awesome actually.

I suppose labyrinths may have to be reimagined as well. As Swiss cheese.

Etc.
