We have gathered enough information to assess the macrostructure of the universe.
At current stage of development of the universe, the ether no longer requires any external (in relation to the ether) influence for the formation of substance. The initial impulse, if it existed, created the starting (very first) gravitational system (the center of condensation capable of condensing the ether into substance), and then continued self-development and self-reproduction of such systems.
The evolution of ether consists of repeated cycles:
— celestial body-embryo with gravitational reactor, which begins to grow;
— then the planet, star, superstar; increasing the amount of substance causes depletion (decrease in density) of ether;
— this leads to the release (evaporation) of the ether constituting the substance, and to the decay (implosion) of the superstar;
— the result is a multitude of scattering celestial bodies-embryos, which evolve into a star cluster;
— and the cycle is repeated in new places, multiplying over and over again.
The process of growth of star systems is similar to the growth of mycelium or mold, or the process of forest growth from a single seed. Therefore, the macrostructure of the universe has a fibrous appearance. For the emergence of substance (stars) in any part of space, which was free from the substance, there must other star to be formed first somewhere in the neighbourhood, and that star must advance thru full path of metamorphose from the embryo with the gravity generator of the substance to superstar, and then to disintegrate. That is, the substance forms a substance. A star can only originate from a previously created substance.
The described scenario is confirmed by astronomical observations of the largest cosmic structures of the Universe in the form of filaments from galaxies situating between the voids.

The universe within 500 million light years showing the nearest galaxy walls, superclusters and galactic filaments. The only thing we can’t agree with in explanation to this picture, – is the estimation of distances of hundreds of millions of light-years. Distance is greatly exaggerated by organized science.
In our universe there are no such structural units as galaxies. Since the galaxies (nebulas) are just the same stars at a later stage of development.
Here it is appropriate to mention the concept of entropy, and the idea of thermal death of the universe. In our picture of the world entropy, as the equalization of the temperature (energy) of the universe has no physical meaning, and is completely unimaginable.
Curious question: is it possible to stop the movement of ether? Or put the question narrower: is it possible to stop the process of transformation of ether into substance and back? A kind of gravitational death of the universe, analogous of thermal death.
The role of the condition similar to the “death of the universe” can play the ether devoid of substance, the ether in a state of maximum energy. This brings us back to the topic of the Initial push with which we started this article, and this topic requires special consideration…
Apparently, once started, the self-oscillating process of converting ether into substance and back is unstoppable. To maintain this process, it is necessary only to maintain the pressure of the ether in the volume of the universe, or in other words, to maintain the amount of ether in a given volume of the universe. This condition requires either an infinite volume and the amount of ether in the universe, or vice versa a finite amount of ether enclosed in a finite volume of the universe. The main thing is that the volume of the ether of the universe does not increase, which would lead to a decrease in the pressure of the ether, and to the disappearance of the conditions necessary for the phase transition (condensation) of the ether into the substance.
The evolution of ether takes place in space by changing (transforming) space. Substance, as a condition of the ether just migrates across the universe by the birth and decay. The process is somewhat similar to the cyclic chemical reactions of Belousov-Zhabotinsky that is a self-propagating, non-equilibrium fluctuations of concentration.
