“Or one might take the tip of a pencil and magnify it. One reaches the point where a stunning realization strikes home: The pencil-tip is not solid; it is composed of atoms which whirl and revolve like a trillion demon planets. What seems solid to us is actually only a loose net held together by gravity. Viewed at their actual size, the distances between these atoms might become leagues, gulfs, aeons. The atoms themselves are composed of nuclei and revolving protons and electrons. One may step down further to subatomic particles. And then to what? Tachyons? Nothing? Of course not. Everything in the universe denies nothing; to suggest an ending is the one absurdity. [...] “Perhaps you saw what place our universe plays in the scheme of things—as no more than an atom in a blade of grass. Could it be that everything we can perceive, from the microscopic virus to the distant Horsehead Nebula, is contained in one blade of grass that may have existed for only a single season in an alien time-flow? What if that blade should be cut off by a scythe? When it begins to die, would the rot seep into our own universe and our own lives, turning everything yellow and brown and desiccated? Perhaps it’s already begun to happen. We say the world has moved on; maybe we really mean that it has begun to dry up.”
