A minimalist quantum Time

What is it about?

Time in quantum physics is Newtonian, i.e. (for an observer) assumed to be universal, unique. However, this is not the only possibility stemming from the general quantum foundations. It is shown that minimalist thinking prefers a concept of local time, i.e. of Time as a local, "personal" feature of an individual (closed) quantum system. This is a technical, non-interpretational view of the concept of time in quantum theory.

Why is it important?

It appears that Time is not necessarily fundamental. Hence non-fundamental character of the ordinary 3-dimensional spatial space is also suggested. Non-fundamental character of Time completely changes the leading paradigm of space-time and opens new routes in describing the quantum fundamental phenomena and their understanding. The results are totally free of any physical and philosophical interpretations.
