20. Randomness
I shall never believe that God plays dice with the world.
— Albert Einstein
We must digress to have a discussion about randomness. To a high-level observer, much of what goes on in DM appears random. Certain structures last for a random amount of time before disintegrating into other structures. The way in which disintegrations take place seems to also happen at random. Yet we have said that DM is a deterministic system! The answer lies in the relationship between superposition and interaction. By far the most common kinds of local events involve a superposition principle, so that the flow of information proceeds outward in every direction, virtually unimpeded by whatever is going on in the space that it traverses. In a large RUCA, where every digit can be written as a function over most of space-time, we can see why each particular digit seems random. Digits throughout most of space-time have a causal relationship to a digit that is here and now. Normally this randomness is not noticed by processes because of superposition; however, every so often one of these random configurations of digits interacts with some process, and determines one of several outcomes. It seems random, it mimics randomness, but it is not random. It is not even orthogonal or independent. Yet it can produce statistical results one would expect of random processes. It is interesting to note that from a computational point of view, a locally determined truly random number is very computationally expensive. If it is truly random, then it is like a real number, and might need unlimited computational resources just to compute one such number. In DM, we get the benefit without the cost; and we can expect a mechanistic explanation of statistical correlations of distant events.
