Skillion

In fact, human experience requires not just one society but a nest of such societies, ordered in special ways. For instance, there need to be societies drawing out all the trains of thought that come together in a single judgment, and there need to be skillions of societies (a skillion is a very large number) tracing causal inputs from the body, the atmosphere, gravitation, human culture, the New York Times, and whatever else provides the context for a single thought.

The trouble with the multiple-universe model is that, however elegantly it may fit the quantum equation for the state vector, most of us simply can't believe in skillions and skillions of universes—each as vast in space and time as the one we think we're in—where everything that can happen really does happen.
