An important example. In the [[Physical Reality|physical domain of Reality]], some of [[fundamental physical quantities]] that characterize the manifestation of the [[Elementary Action]] (in its basic mode that we call [[Perturbation]]) at more complex [[levels of Reality]] (as the level of [[Action]], of [[Information]], the [[Structures of Information]], [[Material Forms]]) can be considered as equivalent manifestations of the same [[phenomena]] and dynamics occurring at the more elementary level of Reality.

The most important principle of equivalence, in the physical domain of Reality, is the [[Principle of General Equivalence]] that describes the equivalence between some of the fundamental physical quantities, which characterize the manifestation of the Elementary Action in its basic mode that we call Perturbation, and, indirectly and consequently, among some related derived physical quantities, which can be considered the expression of those fundamental physical quantities at more complex levels of Reality (as the level of Information, of the Structures of Information, of Material Forms):

The most extended principle of equivalence operates in the physical world, in the real factory of [[space]]-[[time]]. At this level, the most elementary level of Reality, where the occurrence of the [[Elementary Events]] represent the most elementary form of [[Existence]], we can find this fundamental equivalence that give us an explanation of the deep nature of the some basic phenomena and some basic quantity/[[Fundamental Constants of Nature|constant of Nature]].

This principle states that the nature of some fundamental phenomena and some associated physical quantity, that is related to what we call mass and mass density, is deeply connected, "equivalent" for instance, to other important aspects of the elementary level of Reality:
+
*temperature of the Elementary Field or the temperature of space-time (see the phenomena called CMB - Cosmic Microwave Background),
−
*the amount of [[Perturbation]], the density of the elementary perturbations (inhomogeneities/gradients in the distributions of the quantum fluctuations of the Elementary Field that we call Elementary Events) that characterize the Elementary Action,

*velocity of propagation of information/causality in the Elementary Field or speed of light in the void/vacuum.

−
These aspects are equivalent and have a unique physical, natural, basis. In this perspective, we can say that mass does not curve space-time. Mass “is” (can be seen, or described, is the same thing of) the curvature of space-time. And not only, as above mentioned. We call this the [[Principle of General Equivalence]], a specification of the Principle of Equivalence.

Definition

The principle of equivalence describes the fact that in Evolutionary Dynamics there are concepts, phenomena, quantities, apparently of different nature, that, in a deeper perspective, can be considered having the same meaning, nature, origin, amount, value, properties, qualities or intensity, etc.

Or, even more in general, things that appear to be different observing them in the level of Reality in which they manifest, but that appear to be equal or similar if we observe or describe them in the terms of more elementary concepts, phenomena, quantities, at a more elementary level of Reality.

One of the most relevant principles of equivalence is the Principle of General Equivalence, that incorporates an extends the principle of equivalence proposed by Einstein. In General Relativity, the equivalence principle states the equivalence of the gravitational and inertial mass. The gravitational "force" that is experienced locally on a massive body as the Earth is the same as the pseudo-force experienced by an observer in a non-inertial (accelerated) frame of reference.

Description

The most important principle of equivalence, in the physical domain of Reality, is the Principle of General Equivalence that describes the equivalence between some of the fundamental physical quantities, which characterize the manifestation of the Elementary Action in its basic mode that we call Perturbation, and, indirectly and consequently, among some related derived physical quantities, which can be considered the expression of those fundamental physical quantities at more complex levels of Reality (as the level of Information, of the Structures of Information, of Material Forms):

  • the amount of Perturbation, the density of the elementary perturbations (inhomogeneities/gradients in the distributions of the quantum fluctuations of the Elementary Field that we call Elementary Events) that characterize the Elementary Action,
  • mass density of space-time domains, that characterize many physical entities / quantities that we observe or suppose as basic constituents of the physical world: dark matter, dark energy, ordinary matter,
  • space-time curvature of the metrics, that determine the dimensions and the geometric properties of physical reality,
  • temperature of the Elementary Field or the temperature of space-time (see the phenomena called CMB - Cosmic Microwave Background),
  • velocity of propagation of information/causality in the Elementary Field or speed of light in the void/vacuum.
