One of the most important aims of modern physics is the description of strong, weak, electromagnetic and gravitational interactions in a unified way. Attempts to create Grand Unified Theories for this purpose have always been unsuccessful. Let's try to solve this problem on the basis of the Unified Theory of Nature.

Gravitational forces. Gravity is the filtration of the maternel ether through the body (What is Gravity see) – the transit begins and continues almost from the freest (not inside particles, bodies) flow of ether, which practically does not converge and is not yet very dense (The universe is closed  see). The filtration (gravitational) pressure of the ether in this case, proceeding from the essence of Gravity, will be significant only for large sizes of bodies Ng ~ m_{1 •} m₂ (The essence of gravitational mass see). The above is the essence of the so-called "weak gravitational forces".

Electromagnetic forces. When ether is filtered through a particle – an electron (transit) to a vortex – a proton or a cluster of vortices – the nucleus of an atom (Structure of the atomic nucleus see), the ether is already somewhat compacted due to the convergence of its flow to the proton (Fig. 17 see). However, due to the large distance between a very small microvortex – an electron and a proton, this compaction is still not very noticeable. Therefore, the filtration – gravitational ("What is Gravity" and  Formation of protons and electrons see) pressure on an electron relative to a proton is already more significant than on the same electron, but without flow convergence (see above about weak forces). It is already quite difficult to separate an electron from a proton. This is the essence of the so-called "electromagnetic forces"*.

Strong nuclear force. When a vortex is formed from the maternal ether (Formation of galaxies and stars and "Formation of protons and electrons" see), the density of the ether increases, forming a jet that buds off from the general flow of free ether. When the ether moves in this jet, the density of the ether in it sharply increases due to the self-wedging of the jet (Explosions of galaxies and stars see ). A very dense microvortex is formed from this jet (Neutron star - how did it originate see). This microvortex has a very large stock of stability – Inertia (The 1st law of the existence of the Universe  and Essence of Inertia see). Therefore, it is very difficult to break it. This is the essence of the so-called “strong nuclear force” ("Structure of the atomic nucleus" see also).

Weak nuclear force. After the formation of microvortices: protons, electrons and neutrons ("Neutron star - how did it originate" see) during the explosion of a neutron star, the next phase of its life begins. In this phase, under the influence of Gravity, clusters of protons with neutrons are formed – the nuclei of future atoms. More massive clusters – nuclei consist of a large number of protons and neutrons. This indicates that such clusters have a large Inertia. In accordance with the well-known stability criteria, they will have a smaller stability stock – strength, compared to lighter nuclei. Such nuclei will be characterized by neutral stability and even spontaneously lose stability. This is the reason for the existence of the so-called "weak nuclear forces" that hold the components of such nuclei together.

It can be seen from the above that all the so-called "fundamental forces" are due to the movement of the maternal and vortex ether and have a single basis – Gravity and Inertia.

Here at last the modern physics puzzles are solved. Fundamental forses united! What clear head this Unified Theory!

* A. Einstein was also convinced of the unified Nature of gravitational and electromagnetic forces. So in January 1929, a few days before the publication of his article «Toward a Unified Field Theory» in the Proceedings of the Prussian Academy of Sciences, he gave an interview to the London newspaper Daily Chronicle, in which he said: «Now and only now we know that the forces that move electrons in ellipses around the nuclei in atoms – the same as the forces that move the Earth in its yearly path around the Sun»
