(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?
