My explanation of gravity:

energy is a scalar physical quantity,which is a single measure of various forms of movement and
interaction of matter, a measure of the transition of the movement of
matter from one form to another. The introduction of the concept of
energy is convenient because if the physical system is closed, its
energy is stored in the system for a time during which the system
will be closed. This statement is called the law of conservation of
energy.

gravity is the force that closes anopen system(s).

Has anyone wondered why the atoms thatmake up matter are not attracted to each other? If they are at rest.


My answer: because atoms are closedsystems. It follows from the law of conservation of energy that if
the physical system is closed, its energy is stored in this system
for a time during which the system will be closed.
Now on.
If we consider the stone lying on theground as a system of stone-earth, the stone itself consists of
atoms, which individually are closed systems, but the stone itself is
an open system. The same is true of the earth. When the stone lies on
the ground, the stone-earth system becomes closed, local closed,
closed at the point where the stone lies. But stone and Earth are
open systems.

At first glance, there is nothingspecial about it. But I have an answer to why gravitational
interaction is the weakest interaction of the four known fundamental
interactions.

To take the milky Way galaxy . In thecenter of the galaxy is a black hole. A black hole absorbs stars,
thereby increasing mass. The black hole is also an open system. The
star is also an open system./ * I have a version that the blackhole itself does not feed on stars. It feeds on radiation. Radiation
also has a mass. That's why a black hole is a densely Packed object.
It no longer has an atomic structure, but much denser. */
No body in the Universe can beconsidered as a closed system. The closer the bodies are to each
other, the faster they will merge into one system, but the new system
will still not be closed. Any body in the Universe either absorbs
energy, or emits energy, or emits more energy, or absorbs more.
The analogy is this: the average personwhat is the meaning of life? That's right, find a soul mate, wife or
husband. Well, and then how it goes already.
But in any space object the meaning oflife is to become closed. Moreover, the object in the first place
will be closed with those objects that are closer to it.

Even if we consider the whole Universe(stars, galaxies, clusters of galaxies, etc.), in fact the universe
is not a closed system. Because the universe is losing energy. The
energy of the Universe in the form of radiation goes into the relict
background.
In physics, there is the problem ofso-called dark energy and latent mass.It is known that the farther thegalaxies are, the faster they are removed, with acceleration. How can
that be explained? It's simple. Relict background is not a massless
structure, and relict background has a mass. And this mass increases
because the universe is not a closed system. And those galaxies that
are at great distances gravitationally interact with the relict
background.
And these galaxies , 13.8 billionlight-years away from Earth, which are visible through the Hubble
telescope, have long since become a relict background. The telescope
records what it was 13.8 billion years ago. At least, what they
rejected was passed in the relic background.And at every moment of time the relicbackground is replenished with energy. Radiation is energy that has
not entered a closed system when energy is transferred from one state
to another. If the atomic nuclei were continuous, then there would be
no radiation.

And here is the shell (relicbackground) creates such effects - dark energy and dark matter.

why is gravity such a weak force? Myopinion.

The above is proved by the principle ofsimilarity of triangles that the universe has the form of a spherical
octahedron with a colossal degree of partition.

Based on the fact that the universe isa spherical octahedron. you can make the assumption that the atomic
nucleus is also spherical octahedra.This is in good agreement with seventypes of radiation, IMHO.
The above describes the process ofradiation formation. When added together two of the octahedron, so
that the system became closed need to replace the system of
triangulations. As a result of the replacement of the triangulation
system, seven types of segments are eliminated from the new system
(octahedron C).
The opposite is also true. When addingoctahedrons A and B (see above) , to get a closed octahedron C you
need to add seven types of segments. Add a segment to each type of
triangle. Then octahedron C will have the same radius at each point
and will be closed.

This geometric octahedron law can beapplied to gravity.
Radiation is when the sum of the twooctahedra A and b of the octahedron With out the extra segments to
make the system became closed and retained energy over time. (v= c)

Gravity is when the sum of the twooctahedra, and the octahedra With added new segments to make the
system became closed and retained energy over time. (v<< c)
That is, gravity is the reverseprocess. Octahedron C is a relict background. The degree of partition
of the octahedron C is enormous. The number of pieces (segments) is
enormous. And each segment is an open system that tends to become
closed, be it a planet, a star, a galaxy, a black hole, a
superscription, etc.this interaction is very weak, but it covers
absolutely all bodies and acts at distances of the scale of the whole
Universe.
And when astronomers count the mass andvelocity of galaxies, the credit debits don't add up. So you need the
gravitation of the cosmic background to be considered. This, too,
mass and with very a substantial.
They also say that if you rewind theexpansion of the Universe, you get the point of singularity. Its
radius tends to zero, and the mass to infinity.Where did you put the relictbackground?If you add a relict background, you geta supermassive black hole. If this black hole is not affected by
anything, it is closed, then there will be no big Bang. It will save
energy endlessly. A more realistic option is a clash of quasi -
closed systems. Closed systems do not interact with each other.
And when they collided, their energy(mass) was distributed in space according to the octahedron law. And
apparently the speed of this distribution exceeded the speed of
light.

If we add a relict background to thesingularity, we get a supermassive black hole. A certain diameter. If
this system was completely closed, it could not cause A big Bang.
Since there is a proton, a neutron and an electron, it can be assumed
that there was a collision of three black holes with different
electrical charges.The average diameter of these blackholes is the initial minimum step of the octahedron C, the length of
the edge of the Universe . More precisely, if the three systems were
premirovalis (faced) , then the minimum step of the octahedron D.
A+B+C=D+relic background.
