Currently, one of the most promising directions for creating a Unified Theory of Nature is considered to be the unification of Quantum Mechanics with the General Theory of Relativity.

A deep and thorough analysis by the author of the methods, means and results of modern physicists' work on unifying Quantum Mechanics with the General Theory of Relativity (QM with GTR) has shown the following. Their gross mistake is that they are trying to unify the Quantum Mechanics that exists (since it is fruitful) with the General Theory of Relativity that exists (since it is also fruitful). Yes, both sciences are convincingly fruitful, but how can one close one's eyes to the fact that the Standard Model, despite the various tricks of its apologists, does not want to be completed. Neither Albert Einstein, nor Stephen Hawking, nor other enthusiasts have succeeded in creating a Theory of Everything. The 4 fundamental interactions do not want to unite. Gravity remains absolutely uncontrollable. And many other "NOTs".

After lengthy research, the author came to the following conclusion. The only way to unite QM with GTR is to disconnect from QM and GTR and start looking for the common not in the mathematical methods of QM and GTR, but in the micro- and macro-World, that is, in the objects of research of QM and GTR. And this common is only Matter, only Space and only Motion. It follows that the unification of QM with GTR should begin with the analysis and correction of existing concepts about the properties of Matter, Space and Motion of Matter in Space. After this, one can move on to the objects of QM and GTR and correct the concepts of QM and GTR for these objects based on the general concepts of Matter, Space, Motion. This final correction will be the process of unification of QM with GTR.

The specified principles of unification of QM and GTR are used by the author. They are described in  "Working out of the Unified Theory" and successfully applied to a variety of objects and phenomena studied by QM and GTR (see Universality of the Theory). However, some of the concepts of QM and GTR, to our regret, were not confirmed. But this loss was paid for Quantum Mechanics and the Theory of Relativity by an overwhelmingly large profit. A number of obstacles to the actions of QM and GTR were eliminated, and a great many mysteries that had no explanation for either QM or GTR were solved based on new principles. Here are these achievements (see their evidence above in "Universality of the Theory"):

Dualism in QM was eliminated. A coherent concept of the Universe was obtained. The secrets of particles and antiparticles were revealed. The mystery of the Uncertainty Principle of QM was eliminated. The previously unknown deep essence of electric charges and the deep mechanism of their interaction were revealed. An elegant (simpler than Quantum Mechanics) explanation of the Barrier Effect was obtained. A deep physical explanation of A. Einstein's formulas was obtained. The properties of the Black Hole are explained using the properties of electric charge. The 4th disobedient fundamental force harmoniously united with the other 3. The previously unknown physical nature of quantum numbers is revealed. The reason for the existence of different types of galaxies is established. The secrets of galaxy rotation are solved. The secret of the large-mass cluster in the center of the Galaxy is solved. An elegant explanation is obtained for the previously mysterious distribution of galaxies in their clusters and outside of clusters. The secrets of globular galaxies are solved. A consistent alternative to the General Theory of Relativity explanation for the known cosmic radiation background is found. The secret of the tendency of the potential energy of all material systems to a minimum is obtained. The reason for the fundamental property of the universality of motion in Nature is established. A non-corpuscular explanation for the motion of a light beam in a straight line is found.

Consistent alternative to the General Theory of Relativity explanations for the Red Shift are found. The deep physical essence of the Right and Left Hand Rules is established. A previously unknown deep mechanism of neutrino formation has been revealed and the secrets of its properties have been solved. The secrets of galaxy shape anomalies have been solved. The secrets of star velocities in galaxies and their distribution in the galaxy and outer space have been solved. An explanation has been obtained as to why hot stars predominate in open clusters of stars, while cold stars predominate in globular clusters. The secret of stars leaving globular clusters has been solved. The secrets of oscillations in globular clusters of stars have been solved. An explanation has been found for the mysterious arrangement of open and globular clusters of stars in a spiral galaxy. The secret of the certainty of the number of sleeves in a galaxy and the shape of these sleeves has been solved. The secret of the mysterious appearance of protons, neutrons and electrons in space and their internal structure has been solved. A consistent, alternative to the existing, explanation of A. Eddington's experiment has been obtained. Similarly, according to R. Mossbauer's experiment to reveal the effect of Gravity on a light beam in accordance with the General Theory of Relativity. It was established that a light wave has both transverse and longitudinal oscillations. A number of mysteries of binary and more multiple stars have been solved.

A number of mysteries of the Sun and planets of the Solar System have been revealed. The long-standing mysteries of particle spin have been solved. The mysteries of Dark Matter, which unpleasantly disturb scientists, have been solved. The paradoxical nature of the composition of cosmic rays has been solved. For the first time, an essential theoretical explanation of a nuclear reaction has been obtained: an electron plus a proton generates a neutrino plus a neutron. The secrets of how cosmic rays are formed and what is the source of mysterious gamma-ray bursts in the Universe have been revealed. A contradiction-free mechanism for the formation of planets has been established. The secrets of the planets of the solar system associated with their density, rotation speed, and the presence of satellites have been solved. An alternative to the General Relativity explanation for the shift of Mercury's perihelion, an explanation for the elongation of the Moon to the Earth and the wideness of the Earth's equator have been obtained. The secrets of the Earth's magnetic field have been solved. A previously unknown deep secret has been revealed that the speed of light is the maximum possible speed in the Universe. A mysterious reason for the quantum properties of light has been found.

A simpler explanation, compared to QM, of superconductivity has been obtained. A previously unknown deep secret of the appearance of the Coriolis force has been revealed. The secret of the absence of the Moon's magnetic field has been solved. A solution has been found to the problem of the differential angular velocity of the Sun's rotation. The secrets of the Sun's magnetic field have been solved. The secret of a supernova that exploded several times has been solved. The secret of the different masses of protons and neutrons has been revealed. The secrets of the Northern Lights have been solved. The deep secret of Nature has been solved - how man came into being. A previously unknown deep mechanism for the release of a large amount of energy during a nuclear explosion has been discovered. An answer has been received to one of the fundamental questions of science - why there are fewer protons than neutrons in the nucleus of an atom. The riddle of the narrowness of the band of stable nuclei on the diagram of the dependence of the number of protons in the nucleus of an atom on the number of neutrons has been solved. Solutions have been received to riddles that arose during the acceleration of space probes. The secret of Material Space has been solved - why it is sometimes quadratic, sometimes exponential.

Thus, based on the use of general concepts of Matter, Space, Motion and their correction, a large number of secrets of Nature have been revealed, the solution of which was previously beyond the power of QM and GTR.
