made up 71.3% of dark energy and 27.4% of a combination of dark matter and baryonic matter.
Whatever, knowing the nature of dark energy and dark matter, as the fundamental cosmological constant and quintessence, how it all interacts with the ordinary matter, as subjected to numbers in terms of extension, change, force, mass, energy and radiation, is most critical for a single theory of the universe
Since, ultimately, four or five main force-interactions, strong, electromagnetic, weak, gravitational, and dark, would combine into the proto force, the Faraday’s universal force, in the ToE, like as in a super string theory, at the beginning of the universe (up to 10-43 seconds after the Big Bang), the four fundamental forces were once a single fundamental force. One might add up here a hypothetical fifth fundamental force of nature, “dark force of dark energy and matter”, theorizing as a force pushing the galaxies aside accelerating the expansion of the universe up to half of the age of the universe (7,5 billion years) (Krasznahorkay, A. J. et al. Physical Review Letters 116, 042501 (2016)).
That might implies that all the fundamental force-interactions might come out as different manifestations of the prime natural force, the prime mover, the first cause of all changes in the universe, including the original event of the hypothetical Big Bang, the singularity referring to the early hot, dense state considered the "birth" of the universe.
So, the final cause of natural science of physics is, in the most general way, to formulate a system of comprehensive principles uniting and explaining all physical phenomena, physical causes and forces, mechanical, gravitational, thermal, electromagnetic, and nuclear forces, weak and strong.
The very universality and convertibility of natural forces and the reversible relationships of physical causes and thence their inherent integrity inspired Faraday, Maxwell and Einstein to seek unification of all the physical processes by a single set of physical laws.
The very universality and symmetry of interactions of natural forces, or reversibility of physical processes, has inspired great physical minds to discover the basic laws of physics, as symmetry principles and conservation laws, and formulate the quantum theory and relativity principle, as Einstein’s matter-energy relationship or space-time relationship.
The very universality of conservation laws of interactions of natural forces, as gravity, nuclear interactions, or electromagnetic interactions, has inspired to discover one of the basic principles of nature, that the laws of physics remains valid in all places and times in the universe. Regardless of all the changes taking place with physical systems, of any scale and complexity, basic physical quantities, as mass, momentum, mass-energy, or baryon number, remain unchangeable or constant.
But, regardless that the great ideas of forcible interactions, process reversibility, energy and effect convertibility have been guiding physical science since its origination, neither has been properly formulated as the fundamental principle and general law of nature and the universe.
To contribute, we introduced the concepts of
universal force-relationship
convertibility laws
reversibility principles
They are introduced as the highly integrative principles of physical sciences, especially, the natural science of physics and theoretical physics, as the most fundamental laws of nature and the universe (Новик И.Б., Абдуллаев А.Ш. "Введение в информационный мир", М. Наука, 1991, in Russian; see Supplement: Encyclopedic Knowledge Base in Physics).
As a result, the interactions of natural forces are formulated in the new terms of force-relationships, covering the current constructs forces, force lines, force-interactions, or force-fields. Forces are constructed as symmetrical force-relations, forceful interrelationships, efficient interrelations, powerful interrelationships, energetic interconnections, effective mapping, or forcible interactions producing physical changes and effects.
Natural forces are engines of the universe and being studied much less than the whole subject deserves. It is forces, their actions and interactions, determine the structure of the universe at all its levels, microscopic or macroscopic or cosmological. We know little about forces, their nature and properties, kinds and laws and relationships, some even hypothesizing that in unified field theories “all forces are fictitious”, or pseudo forces. Most references here traditionally go to the use of Newton's Second Law for a definition of force, which was disparaged as essentially a mathematical truism by notable physicists, philosophers and mathematicians looking for a more substantive definition of the concept of force, as the principle of all physical science.
Still, applying symmetry to forces, the third law pinpointed the key feature of forces: all forces are interactions between different bodies. That means that they have the nature of interrelationships of power, efficiency and energy, what could be generalized as a symmetrical force-relationship. In other words, there is no such thing as a unidirectional force or a force that acts on only one body, in one progressive direction. Whenever a body exerts a force F on another body, the other one exerts a force −F on the first body, now in the regressive direction. F and −F are equal in magnitude BUT opposite in direction, having both magnitude and direction as vector quantities.
This action-reaction law, with F called the direct "action", or progressive force, and −F the reverse "reaction", retrogressive or inverse force, is making a decisive inductive case for the most fundamental truth about nature.
The truth of natural causes or forces is that the action and the reaction relationships are universal phenomena applied to all physical interactions and forces, fundamental and non-fundamental.
The Diversity and Unity of the Force-Interaction: the ToE as the Holy Grail of New Physics
All forces are hierarchically related, making up the natural hierarchy of forces, forces, force lines and force fields, topped by the super symmetry force-interaction, a single universal force of coming Theory of Everything (ToE), or Final Theory, Ultimate Theory, or Master Theory, a single, all-encompassing, consistent and complete theoretical framework of physics linking together all the physical properties and phenomena of the universe.
At present, there is no theory of everything that includes the standard model of particle physics and general relativity, such as to calculate the fine structure constant and the mass of the electron, hoping that a deeper search for new particles and dark force at the large particle accelerators could provide critical input for the ToE. There are a number of candidate theories to unite general relativity and quantum field theory, designed as the working theories of quantum gravity: string theory, superstring theory, M-theory, loop quantum gravity, causal fermion systems, and causal sets.
The last two theories are recent developments and in line with our Causal Category Theory of Everything capable to generalize and complete new candidates for a unified physical theory, as causal sets program and the theory of causal fermion systems, considering general relativity and quantum field theory as limiting cases. In the causal sets program, the founding principles are that space-time is fundamentally discrete and that space-time events are related by a partial order, having the physical meaning of the causality relations between space-time events.
Ultimately, the ToE would unify all the fundamental interactions of nature, gravity, strong interaction, weak interaction, and electromagnetism, as well as shedding light on a postulated inflationary force, dark energy and dark matter.
As such, it is makes the Theory of All Forces in the Universe, ordered by the subordination and inclusion relationships (Abdoullaev A., Reality, Universal Ontology and Knowledge Systems: Toward the Intelligent World, IGI Global, USA, 2008):
