Being and Becoming in Quantum Gravity (or The Birth of a Baby is not a Baby)

Anyone who wishes to attend this talk is welcome. The talk will be 4.5 Einsteins (out of 5).
Abstract: I will describe a dynamical model of a discrete cosmology — called Classical Sequential Growth — that has been proposed as a stepping stone along the way to full quantum gravity. I will present Sorkin’s argument that this model is a counterexample to the claim that relativity means that the future must exist. I will point out that the model contains two different types of physical thing. One is the Past, which is subjective. The other is the Birth Process by which the atoms of spacetime come into being. Both are real in the model and, I will argue, both are needed if the model is to coordinate with our experience. The price that must be paid for this advance, however, is that the model does not provide a “God’s eye view’’ of the universe.
