So does that mean that a world can exist through purely a system of numbers, values and rules? This system can exist without any physical matter, as it is only a mathematical pattern/system, and not an object. The system can include such things as "time" and "dimensions", but only the mathematical interpretations behind them. As this system of rules and patterns evolves to deeper and deeper complexities, things resembling 'life' and 'objects' can exist. (It is still only the values and properties of these things that exist, and not the objects themselves). I propose that humans and the universe are nothing more than one part of a mathematical system that can and always has existed without necessary "existing" any more than the number 4 'exists'. This explains why there is no real analogy or familiarity to explain the phenomena in the quantum world, the particles and fields really are nothing more than values and numerical properties that follow rules. This also means that every other possible (stable) system of values and rules does exist just as much as ours does (which links in with the multiple universes idea), which explains how life originated despite the improbabilities. Furthermore, I think that if something is possible, then it has to 'exist', just because we are nothing but a set of values following a set of rules. Tell me your thoughts, I haven't had too long to think about it, I just wanted to here someone else's view.
