A brief panorama of contemporary researches on the concepts of space, space-time and its relations to nonlocality is presented. In this regard, some historical aspects of the concept of space-time and quantum theory are considered under the perspective of possible connections between them. It is argued that, even though it is accepted the important role of each one for the topic, there are numerous gaps between mathematics, physics and philosophy that deserve further attention on this old theme.

In this paper I consider the concept of time in a general way as daily human time and then within physics with relation to mathematics. I consider the arrow of time and then focus the attention on quantum mechanics, with its particular peculiarities, examining important concepts like temporal asymmetry, complexity, decoherence, irreversibility, information theory, chaos theory. In conclusion I consider the notion of time connected to a new theory in progress, called “Primordial Dynamic Space” theory.
Here we analyze the physical concepts of non-locality, multi-universe, and cosmological principle in the framework of a space-time discrete model previously developed. In previous developments of this model we have elucidated as derivative concepts those of time, space-time, reference frame, particle, interaction between systems of particles, field, interaction between fields, detector of particle, and wave function. We start from the primitive concept of preparticle and four postulates alluding simple concepts. The fundamental postulate says that space-time points can be represented by equivalent classes of points of crossing between particles having the same structure. In this way each point of space-time is represented by an equivalent class corresponding to a different structure from the one of any other equivalent class representing a space-time point. We have considered a new way to define system of observation and detector of particles, which leads to non- local properties of the space-time model considered. Finally we have speculated about dark matter and dark energy in the frame work of our model.

A literature review of related articles, either by affinity or by contrast, to a fundamental theory of time and space - time previously developed. It shows how from a primitive concept of preparticle and membership relation of set theory, and four postulates that refer to simple concepts, derived concepts of time, space-time, reference frame, particle, fields, and interaction between fields are obtained. The problem of the of time is analyzed and a paradox whose solution goes against the idea that this direction is fixed by the increase of entropy prescribed by the second law of thermodynamics is examined. In our theory this direction is unique to each reference frame, and is an intrinsic property of time. Two kinds of particles are described as derived concepts, and it is shown that one of them fullfills the Bose-Einstein statistics, and the other one fullfills the Fermi-Dirac statistics. We also consider the analysis of the wave function concepts and particle detector as concepts derived from the mentioned theory. Using these concepts, the process of locating both a macroscopic body (typical location) as well as one of a microscopic scale (quantum localization) is analyzed, and the significance of the location is examined in both cases.
In this paper I consider the concept of time in a general way as daily human time andthen within physics with relation to mathematics. I focus the attention on quantum mechanics, with its particular peculiarities, examining peculiar important questions like the temporal asymmetry, the Prigogine’s position and the time-reversal operator of Wigner. I conclude considering the theme of the temporal asymmetry in relation to decoherence and irreversibility. Interesting imputs related to education science will be done.
Space and Time are essential ways by which humans think about their environment. The mathematical parameters associated with these concepts appear nearly in the same way in the formulation of both the classical and the quantum theories, but cer tainly not any more at the level of our intuitive understanding of their results. This paper aims to explain why it can be so, starting from an analysis of the way some basic principles are introduced in these theories. These principles are: localisation in space, isolation of a system, state of an isolated system, and causality. The problem of quantum non-locality is analysed again. It is shown that localising a microscopic entity can depend on the kind of localising experiment one performs. I give an example of an entity which will be considered as localised or alternatively as non-localised, depending on the localising experiment. I also discuss the ideas of time and of duration in quantum physics. I show that if duration can be properly defined for a statistical set of particles, it is not so for the individuals.
