The interpretation of some phenomena of nature deviates in PIT from that in quantum mechanics. The interpretations of physical effects are based in PIT on the principle of Hamilton applied on a description of elementary objects by four dimensional correlation structures which are characterized by physical information.
The communication relations of quantum mechanics are interpreted in the PIT as four dimensional structures with oscillator properties; action is formed by the time oscillator on correlation space; the formation of action can be lead back on the interaction of two components of the vector potential with the same action and with different signs.
If they are described by four dimensional correlation structures, physical effects of matter, charge, radiation and vacuum can be explained on the basis of their properties and interactions.
Change of movement occurs by a change of the amount of action (physical information) in the scalar oscillators of elementary objects.
The wave function of quantum mechanics contains the properties of elementary objects in space time, because by applying an operator on the wave function, that is using the Lagrange density, the properties of the correlation structure are used.
Physical information as structure information (without change of action) can be transmitted between elementary objects outside the conditions of special relativity theory,[7].
In frame of the PIT only the Maxwell vacuum is existing, [5].
All interactions are causal and have a time arrow. This follows from the oscillator properties. The propagation of physical information in vacuum is time directed.
All properties and interactions of elementary objects at the end can be described on the basis of physical information, being part of four dimensional structures, formed by four dimensional fields (presently the vector potential is used), acting under conditions of the principle of Hamilton,[1]. In the present position of development of the PIT this is only possible for electromagnetic and gravitational interactions.
