You can use a very large, possibly flatened sphere. This will make it gently 
curve down from the center.
For example:
sphere{0, 10000 scale<5,0.01,5> translate -100*y}

It's possible to use an isosurface to do the same, with the benefit that you can 
alter the actual shape, but with a slower rendering speed.
