8.1 Introduction

Having explored our models and some of their behavior, we are now in a position to discuss their potential for application to physics. We shall see that the models generically show remarkable correspondence with a surprisingly wide range of known features of physics, inspiring the hope that perhaps a specific model can be found that precisely reproduces all details of physics. It should be emphasized at the outset that there is much left to explore in the potential correspondence between our models and physics, and what will be said here is merely an indicationand sometimes a speculative oneof how this might turn out.
