Ignore the yellow vase. These are two little elephants I made in 1998, with little bent nails for tusks. The white one is made of a spongy modeling compound that's almost lighter than air, and the black one is much more dense and far heavier.
This is Edwin Hubble. As I once read in some book whose title I've forgotten, "In 1929 Edwin Hubble discovered that not only are all measured galaxies receding from one another (and therefore, receding from us), but that their velocity of recession is proportional to their distance from us. This ration -- of recession velocity to distance -- is called the Hubble Constant."
