Reality is a whole, a unity, the Universe in evolution. Only for descriptive purposes is very useful to represent it as a multilevel structure, where successive layers of Reality, successive nested levels go from the most elementary (where the Primary Source produces the Elementary Events, the Elementary Action, the “substance” by which all the Reality in constructed, to the most complex that comprehend the cosmic structures, the living beings and all their cognitive expressions, the Universe as a whole.

Always keeping in mind that fundamental unity, we can imagine the various levels of Reality as separate worlds, with different principles, laws, dynamics, etc., different expressions, declination, fundamental principles, laws, dynamics that describe the whole Reality. This abstraction can help us to face more easily the immense complexity of Reality, it can help us to develop better systems of formalization, allowing us to treat high-level structures as macro processes, without necessarily having to describe them in terms of more elementary level structures.

An example… Think of you walking in a street… Hyper simplifying the structure of Reality, for briefness, reducing the number of levels involved in the existence of that situation…

• Going from complexity to the more elementary levels, at the top there is the entire Universe, the Cosmos and all its structures (including Dark Matter and Dark Energy) influencing everything in the part of the Universe where we life, influencing you, your structure, your dynamics. This is the realm of General Relativity.
• Then, leaving out the cognitive dimension of Reality, concentrating only on the physical side, we must consider the level in which the laws of classical physics govern the motion of your body, the motion and the functioning of the moving parts within your body, your heart, your lungs, your blood, the other solids. liquids and gasses inside you.
• Then we must consider the molecular biochemical and chemical level, with all the reactions that sustain the life of your body.
• Then the atomic level, where the electron interact to perform the chemical reactions. This is also the level in which all the electromagnetic radiation, all the energetic exchange happens inside and outside your body.
• And more, we must consider the nuclei of atoms, their dynamics, everything that gives physical stability to the mass we are composed by. These are the levels where the quantum manifests with all its power and weirdness, the realm of Quantum Mechanics, the domain of quantum information and the relative structures, particles and waves and their strange interactions.
• But we are not at the end of our journey. Indeed, there is some other level to explore. They separate us from the most elementary level, where Reality is incessantly formed, where the substrate of the whole Reality, the Elementary Events, that compose the Elementary Action, are incessantly created and participate to the evolution of the Universe.
• Then, we will find the level of the subatomic particles that compose the atoms of the ordinary/baryonic matter, particles (the quarks and gluons, and the other bosons) that stand side by side with electrons and neutrinos in the three “generation” in Standard Model of Particles. All these particles, in this model are considered and named as Structures of Information (Waves, Vortices and Interactions).
• This is the level of Information / Energy, where the three evolutive operators, Organization, Transformation and Selection incessantly act toward the formation and the conservation of those Structures.
• And, digging more in deep, we will find the level of Action, (the Derived) Forces and Fields interact to produce the (Derived) Events from whom organization the Structures form and, in turn, interact and organize to produce atom, molecules, etc. and all the high level, higher complexity structures and forms that compose the Universe in Evolution.
• Then, for many orders of magnitude till the Planck Scale we will see signs of an energetic dynamic “turbulence”, that in standard physics is represented by virtual particles, popping up and down in the quantum vacuum, appearing and suddenly disappearing. This is the product of the Action of the Derived Forces on the Derived Fields, creating Events that try to organize in Structures, that evolutively can’t reach a state of causal permanence. It is an infinite “ocean” of Derived Action that tries to become more or less stable Information (Energy), the incessant fluctuations of the quantum vacuum.
• One more step lead us to the Planck Scale, where the Fundamental Entities, expressions of the Primary Source, the Fundamental Force and the Elementary Field, incessantly interActing “create” the Elementary Events, the Elementary Action, the most elementary “substance”, the causal and variational (spatial and temporal) substrate from whom the whole Reality “evolve”. From the first organization of that “substance”, of the Elementary Events, Space and Time emerge and evolve toward the present vast complexity of the world.
