(p. 23) Suppose we have a physical theory N of complexity C representing a physical situation P. In order to calculate what will happen in a particular circumstance in P we must carry out a computation of complexity C. We can exploit the assumed correctness of our theory N, by preparing the physical system P so that its initial conditions, I, correspond to a particular computation, Comp., in the theory N. Then the system can “empirically do the integration”.

(p. 36-38)Brief Summary of my main results of Emergent Gravity

This leads to questions of physical acceptabilty already at the classical level. Can we obtain the classical “Einstein tests” successes from this theory with this symmetry?
