Comments on the Problem of Time

چکیده
The problem of time, considered as a problem in the usual physical context, is reflected in relation with the paper by Kauffman and Smolin ([5]). It is shown that the problem is a misposed problem in the sense that it was raised with a lack of the recognition of mathematically known facts. We found an idea on time similar to ours in the paper “A possible solution to the problem of time in quantum cosmology” ([5]) by Kauffman and Smolin. Their argument concerning the nature of time seems to converge with our understanding of time as local notion ([1], [2], [3], [4]), even though we come at this issue from completely different angles. That their idea might lead to our notion of local time can be seen especially from the summary passage in [5], near the end of the section entitled “Can we do physics without a constructible state space?”: They offer a way of interpreting the evolution of quantum states in terms of a set of discrete, finite spin networks, each member of which has a successor network. They argue that by focusing attention on finite successor states it is possible to construct the relevant (local) probability amplitudes without constructing the total Hilbert space. They write: The theory never has to ask about the whole space of states, it only explores a finite set of successor states at each step. ... On leave from University of Tokyo
