I understand that the explanation of the Big-bang and the consequent expansion of the Universe lack the slightest consistency and logic to be taken into account in the cosmological reality.
Therefore, here I will make a small discussion that can clarify that inconsistency that I say these theories or explanations have.

1.- Question: When the Bib-bang was produced from an infinitesimal of space-time and energy and after that, what is it that expands: 1A) Space and matter; 1B) Only space and but not the matter?

1A) Space and matter expand together: Impossible option.
In this case, as the measurements of space (and ourselves) are measured with a unit of matter (1 meter, Paris platinum metric unit) if space and matter are expanded at the same time, we will not notice any difference or distance between material elements (galaxies, etc.), since the unit of space increases the same as the unit of matter.

1B) Only expand the space, but not the matter: Impossible option.
If only the cosmic space expands, but not matter, and therefore the metric unit of space remains unchanged, then we would see how not only the galaxies move away at 2,000 k/s, but also galaxies increase its volume, also stars of galaxy increase their volume; the planets of the solar systems go away from its nucleus; the moons from their planets, etc. But we see that this is not the case.

2.- So what do we see really happening?
Well, what expands or moves away are the galaxies between them within a space-time unalterable in dimension.
Remember that if space or time were expansive or simply relative (relativity), you could never measure real speeds.
Even the speed of light would be relative, depending on the space-time through which it moves, which we know does not occur.
* For the speed of light (c) to be 300,000 km / s., in all places in the universe, it is necessary that space and time are also stationary and equal in all places in the universe, since (c = s/t).

3,. Summarizing, that space and time are stationary (stable and unchanging) and universal (non-local) elements and that after our great explosion (Big-bang) what expands are the particles (galaxies) into which was divide the great concentration of matter-energy that was there.

* My model: A), B), C)
A) My theory assumes that not only did galaxies come out of that great explosion or Big-bang, but that the larger particles of matter were left behind because they had much lower speed, and that we could no longer meet them on our road.
B) The universe is infinitely larger than we think today, with multiple explosions of matter-energy (Big-bangs) constantly existing in different places and cosmic levels.
C) Then and "from the birth of the Cosmos or Universe", space and time (coordinate of the Universal Movement) are stationary and universal (non-local), which neither expand nor contract, and so, they are unalterable.
In the same way, comic energy, gravity and matter "always" existed, and our Big-bang was just an explosion of matter from the quasi-infinites that occurs continuously in the Cosmos and at all levels of it.

By joining the space and universal movement (with its time coordinate) this union would logically be made in a certain and constant proportion.
Well, the resulting cosmic energy is manifested as fields of drag force, and therefore containing the characteristics of the forces of being composed of two natural physical parameters such as: Field intensity (I) and speed of execution of the force field (V).
Therefore, (applied force) Fa = I.V
Well, this constant of maximum speed of execution of fields and vectors of force of cosmic energy is C.
Therefore, any field of forces can join and be added with others to achieve greater intensity (I), but for many vectors or fields that are joined, their maximum execution speed will always be the same as (C).

Thank you.
