Consider an object–a corpse. The body of a dead man.
1. In one sense, it is utterly insignificant. It is so small. In its milieu, it is just one among many. Even in life, there was nothing about the construction of this body that made it stand out. And its milieu was just one small portion of the surface of its world, which surface was itself tiny in proportion to the actual earthy, airy, watery mass of the world, which is itself a flyspeck, a nothing, in proportion to the size of the sun that dominates the local area. But even the sun is nothing in comparison with the emptiness of the solar system. And the solar system is nothing in the galaxy, and the galaxy is nothing in the universe.
There is an emptiness called the universe. And within that emptiness, there are unimaginably tiny emptinesses called galaxies. Anything smaller than those smallest of objects are not just small–they might as well not exist.
