Excerpt
Excerpt: Introduction At present we have no theory of the phenomena of time and space. Rather we have a very successful phenomenology given to us by Einstein. We regard Einstein's model as a phenomenology for the simple reason that in setting up this model one makes very explicit assumptions about time and space. For example one of the key Einstein assumptions was to assume, in addition to the very phenomenon of time, that time is local, which contrasted sharply with Newton's assumption of a global time. We take the defining indicator of a theory to be the property that it predicts phenomena, but does not have those phenomena explicitly or even covertly built into its axioms. Well known examples of successful theories include the atomic theory: it predicted the existence and properties of atoms, molecules, etc, but contained only electrons and nuclei in the axioms. A second example is that of nuclear physics: Quantum Chromdynamics (QCD) begins with quarks and gluons and predicts the phenomena of hadrons, nuclei etc. In this example there was a long period of phenomenological modeling in which hadrons were described by elective actions, or equivalently Hamiltonians, involving hadronicelds. The structure of these elective actions was obtained by appealing to various symmetries that appeared to be manifested in the hadronic data. These examples illustrate the idea of emergent phenomena.
