**In the beginning was the code**

*There is a fastest, optimal, most efficient way of computing all logically possible universes, including ours — if ours is computable (no evidence against this). Any God-like “Great Programmer” with any self-respect should use this optimal method to create and master all logically possible universes.*

*At any given time, most of the universes computed so far that contain yourself will be due to one of the shortest and fastest programs computing you. This insight allows for making non-trivial predictions about the future. We also obtain formal, mathematical answers to age-old questions of philosophy and theology.*

**Is the universe being created by a computer program?**

*Calculating Space*discusses how a particular computer, a cellular automaton, might compute all elementary particle interactions, and thus the entire universe.

**Computational theology**

*your*own life must be very important in the grand scheme of things.
