Steve Dufourny Dear Steve!
Thank you for your interesting questions.
Here's your first question:
“What is the origin of this concrete matter of Nature and what is its essence?”
The very formulation of this question tacitly (by default) assumes that matter has some kind of beginning.
But matter, like NATURE, has no beginning.
Matter and NATURE do not and will not have any end.
(1). NATURE has no beginning, and NATURE will not have any end.
(2). NATURE is eternal in its existence.
This is the absolute truth.
But I arrived at this absolute truth as a result of my lengthy dialectical-materialistic reasoning.
You can consider this truth one of my scientific hypotheses.
An analogy helped me.
The evolution of NATURE is like a straight line in mathematics. A straight line has neither beginning nor end. I also put forward a hypothesis about the cyclical nature of Nature's evolution.
In this case (for both hypotheses together), the evolution of Nature is similar to a sine wave (the mathematical function sin).
Alternatively, this analogy leads to the model of an infinite coil spring.
A third alternative, this analogy leads to infinite circular motion.
Any analogy contains cyclicity.
I put forward a third hypothesis: one cycle of Nature's evolution represents the complete evolution of a single universe.
Thus, I conclude that the evolution of Nature represents a sequence of universes.
This means that the evolution of the Universe has its own time limits. There is a beginning to the evolution of the Universe, and there must be an end to the evolution of the Universe.
The evolution of one Universe is a time-limited process.
Immediately after the completion of the evolution of one Universe, the evolution of another Universe begins.
The evolution of nature, however, is not time-limited. NATURE is infinite in the time of its existence and in its evolution.
Since NATURE is infinite (eternal) in the time of its evolution, then nature fundamentally has no beginning.
Nature has no reason for its emergence, existence, and evolution. Because NATURE eternally exists.
This is why all possible searches for some beginning, some primary principle, some primary cause of NATURE are doomed to failure. All these attempts have failed.
(3). Nature is causeless!
This is a simple and clear conclusion. This is another absolute truth!
I will continue my story (my answer).
According to another hypothesis of mine, NATURE is a quintet:
(4). NATURE ::= <Singularity, matter, void, UCN, FLN>
[ Nature as an Objective Reality https://philpapers.org/rec/YUSNAA ]
If NATURE has no beginning or end, is eternal in the time of its evolution, and is causeless, then the same applies to the entire "quintet."
This also applies to matter.
Thus, matter has no beginning, it is eternal in its existence, and it is causeless.
The question of the essence of matter!
My answer is:
“Matter itself is its essence”!
Matter is the most important essence of nature, along with the Singularity, the void, the unique constant of nature (UCN=1.210 256*10^{44}), and the fundamental law of nature (FLN). The FLN is the law of the circulation of matter in nature.
Time is also the most important essence of nature, intimately connected to matter in motion.
