Dear Alberto, I disagree, but like the direction of your thinking.

It would embrace the category of emulations, simulations, representations and all other information related aspects of the universe. It is not necessary for this Category to be identified with the physical world. Yes, it must be related to the physical but that relation can be a morphism to another Category: that of physical objects, forces, thermodynamics, energy, etc. Two Categories, side by side, separate yet related. If we remove the possibility of distinguishing the members of the Categories they collapse into singletons and then, and only then, are Identical. > > Everything is legoland because everything can be emulated using lego > pieces?

Computations that generate output that is identical to their input exist.

If the functions of an Isolated physical system are such that the transformations they induce in/on their cover space (?) of representations are a simulation of the physical system, what obtains? A one to one map of the system that co-evolves with it. When we consider physical systems interacting with each other, could they additionally have partial emulations of each other within their "self-simulations"? > > > -- > Alberto. > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
