We start our unprecedented journey by descending to the absolute "bottom line" level of Nature and ask ourself this simple but pivotal question:

In physical terms, what is the absolute simplest structure that a domain or volume can have ?

To this, one may respond with the trivial answer that the simplest structure is no structure at all, i.e., that the domain be unstructured.

Vacuum by being devoid of everything is such an unstructured entity, and therefore, is the most trivial candidate. The answer that emerges is therefore as follows: "fill up" your domain with vacuum, and you most certainly will have the simplest physical structure that a domain/volume can be endowed with. So far so good.

But now, let's say that someone else will intervene in this discussion, stating that we may conceive as an equally good answer to the posted question by "filling up" the respective domain not with vacuum but with some unstructured substance which may be called xenosubstance (XS) ("xeno" in Greek meaning "strange"). Thus, the most general answer that will emerge is that any admixture of xenosubstance and vacuum would constitute the most general absolute simplest physical structure that a domain, a volume, or a space can have.

We call then the xenosubstance and vacuum as the primary ingredients of Nature (PINs) and their admixture as the primary or primeval admixture of Nature (PAN).

We mark this first important result of TRUTON as follows:

.

The admixture of xenosubstance and vacuum represents the most general representation of the bottom-line physical structure that Nature can have.

Two and only two basic representations of this primordial admixture are possible as illustrated in Figs. 1A or 1B.

The two primordial admixtures of xenosubstance (XS) and vacuum (V).
FIG. 1A	or	FIG. 1B
Here we have a representation of "patches" of xenosubstance (XS) immersed in vacuum (V).		In FIG. 1B, we have the reverse representation: vacuum "bubbles" immersed into xenosubstance..
.
FIG. 1AB		FIG. 1BA
A composite representation: in FIG. 1AB and FIG. 1BA above, we have two (2) respective composite pictures where the right side "patch" of xenosubstance (of FIG. 1A) and the right side "bubble" of vacuum (of FIG. 1B) have been replaced respectively with the entire corresponding system furnished in FIGs. 1B and 1A.

These two basic representations can, in turn, be combined further in an indefinite number of ways as illustrated in the above two (2) representations of FIGs. 1AB and 1BA, respectively.

! PASS WITH CARE				We emphasized the word "indefinite " from the previous sentence since any time, in a physical description of Nature, we encounter the words "indefinite" or "infinite" we shall be on alert as that is an unmistakable indication that something is wrong with the respective representation in question as these two words, "indefinite" and "infinite", have no meaning within a description of Nature, they only can have meaning within the context of Mathematics. Examples of such meaningless physical descriptions are for instance, infinite speed, infinite mass, infinite density, infinite volume, infinite temperature, etc.
				We shall express this paramount recognition into the
		.		First Fundamental Principle of Nature: In Nature, no physical parameter of characterization can reach the infinite value.

Thus, from this alert furnished by the First Fundamental Principle of Nature, we know that we need to add more detail to the starting point since we know that we cannot have an infinite number of representations for the primary admixture of the Universe. The uncharted landscape of our journey demands extreme caution for each and every single step that we take so let us proceed cautiously.

We introduced xenosubstance and vacuum as the primary "ingredients" of Nature. As in Mathematics, this means that these two "ingredients" by the virtue of being primary cannot be reduced one into another or into anything else nor produced through any means. We shall express this recognition through our
.			Second Fundamental Principle of Nature:
			The primary ingredients of Nature, xenosubstance and vacuum, are irreducible in the sense that there is no physical process that can convert one into another, reduce them into something else, or generate them from something else.
REMARK: From the 2nd Fundamental Principle in Nature it follows that neither xenosubstance nor vacuum can be produced in Nature by any means --as these "ingredients" or "elements" are given entities at the baseline foundation of Nature.
!			The first basic question that we need to answer is whether or not the two basic representations provided above in Figs. 1A and 1B respectively for the primary admixture of Nature are truly independent one from another or whether in fact one can be derived from another.
If in fact the two representations (Fig. 1A and 1B) are truly independent (i.e., that they cannot be derived one from another), then we will have the additional burden of choosing which one must be the correct representation. And this is because of the recognition
that the current Universe could not possibly be built out of two independent primary structures of Nature.
Without having a single denominator nothing can be build without collapsing.
To study whether or not there is a transformation capable of transforming one representation (or picture) of the primeval admixture of Nature into another, we need to recognize first that
i) any transformation (by merely being a transformation) imply the existence of a motion of some sort; and that
ii) we need to have a better formulation of the two primary ingredients of Nature --the xenosubstance and the vacuum if we are to understand what transformation(s), if any, they are capable of undertaking.
Since we are at the very begining of our journey where we are laying down the foundation for the path yet to be paved and traveled for our "outwards" study of Nature, we know that, as in Mathematics, we need to have a body of primary propositions --the axioms which shall stand as the pilars for our (outwards deductive rattional) theory. But unlike in Mathematics, our introduced axioms must have a physical meaning and justification for their existence. So far, at the axiomatic level, we have introduced vacuum (V) and xenosubstance (XS) as the primary ingredients of Nature. We also introduced two basic forms of representing this primary admixture of Nature (Fig. 1A and 1B above) which, in turn, we noted that it can be combined into an infinite substructure (Fig. 1AB and 1BA above) --an absurdity by the First Fundamental Principle of Nature. Thus, we are faced with our first challenge --that of selecting the unique representation of the primary admixture of Nature. And that choice is between the representation vested in Fig. 1A and the representation vested in Fig. 1B.

!

.

Regardless of the particular primeval representation (be it the one of Fig. 1A or the one of Fig. 1B), xenosubstance and vacuum are part of the same thing --the primeval admixture of Nature. Therefore they must somehow reflect that bottom-line alliance in a most fundamental way. The see the connection of that primary alliance of the constituents of the primary ingredients of Nature (PINs), we obviously need to add additional properties of characterization to the PINs, not only to differentiate them, but also to see in which way they are being united --the subject of our next sections.
