I didn't mean that the laws of physics once set could change, merely that there is no need to formulate, for example, the laws of how sub atomic particles behave until conscious minds in the simulation start examining them. On a simpler level, you can have a simulation of the solar system on a computer that simply plots where planets are in their orbits - like an Orrery. Or you can have the computer programmed with the laws of gravitation and give each planet a mass and velocity and the computer calculates where the planets are, and such calculations should agree with observed reality. My concept was that the simulated universe would operate on the former basis until such time as it was necessary to move to the latter. Even now, you could program your computer with Newton's laws and get away with it for a while, but for accuracy over long periods you would need Einstein's equations.
