The primeval dynamics of Nature (PRIDON), was introduced as consisting of XB-blocks gliding in different directions in the xenovoid (XV) space --the HOST. Through various collision (to be discussed in detail in the next section), compressional XB-masses will be formed that, as recognized in the 7th FUPON, will generate new qualitatively states. In this section, we identify now those qualitative different states of existence of xenosubstance (XS) that the variation of density can produce. We begin, of course, with XS's default state --the xenobase (XB) and continuing with XB's subsequent compressed states.

I. Xenobase (XB) state was introduced as the natural default state of existence of matter --a state that represents a material continuum at the lowest possible material density . Upon reflection, we add these properties of charactherization:

..1. The unielasticity (or the compress-compliant) property stating that XB has no resistance towards compression regardless how small it is. And, .2. The unirigidity (or the stretch-resist) property stating that XB cannot be stretched. .Note: The above dual concomitant properties of the xenobase is being referred as the uniflex properties of the xenobase state. .Remarks: .a) When XB is being pulled apart (in an attempt to be stretched) or tensioned in any other way, the force of that tension is being transmitted into the XB state transforming that XB state into a tensioned XB (tXB) state. Unlike a normal XB (zeroXB) state, a tensioned XB (tXB) state will oppose resistance towards compression, the "power" of that resistance being equal (but opposite) to the force of the tension created. That acquired power is due to its acquired tensional energy called tensoEnergy (teE). As soon as the tensional force is being removed, the tensioned XB state (by having no mechanism of keeping its acquired tensoEnergy) transforms back into its normal XB (zeroXB) state since, as stated, the XB state has no capacity of keeping the infused tensional energy. Because of the acquired resistivity towards compression, the tXB state is also called the stiff state of XB. .b) By the 4th FUPON, the tensoEnergy (teE) of a xenobase mass cannot reach the infinite value. Therefore, an upper finite limit value for teE must exist --called the xenobase's breakup limit-- above which the xenobase will disintegrate. 3. The XB being subject to stress beyond its stretch-resist limit will disintegrate and pulverize transforming it into XB-particles forming a XB-"dust" called the light xenodust (lXD).

4. When a XB-surface receives a hit in a point of its surface, that hit will be propagated from that point into a surrounding or neighbouring surface called the hit's spill-surface that extends until its edges can advance inwards (as an open accordion on one end) impinging inwards in the direction of the hit. We call that conductivity process of the hit on a XB-surface the xenoconductivity (XECO) property of XB.

.Remark: XECO is a rather subtle property of XB springing from its complex uniflex property: on one hand, XB cannot be stretched, behaving thus as an absolute rigid body; on the other hand, XB can be compressed opposing no resistance, behaving thus as an absolute elastic body. .The fringes of the spill-surface of a hit are defined where a "vertical" impingement parallel to the direction of the hit can begin since a XB-surface to be able to be compressed needs a "vertical" impingement (as in an open accordion moving inwards "vertically" from one side). .The "propagation" of XECO on a hit XB-surface is thus a direct consequence of its uniflex property.

II. A XB-volume by a compression or shrinkage, regardless how small, will transform into a compressed or condensed xenobase state called the xenofluid (XF) state. We can say that the XF-state is a XB-state that has acquired (or was infused) with compressional energy called ergoEnergy (erE). The xenofluid at its lowest density is called thin xenofluid (tXF) or thinofluid or still xenothin and, at its highest density is called a xenogel (gXF). A xenofluid mass whose density is between its extreme density values, i.e., between xenothin and xenogel is called a xenodense fluid or a densofluid (dXF) .

Note: When no specification is provided, by xenofluid (XF) is ment xenodense fluid (dXF).

The xenofluid concept, denoted as XF-state or XF-mass, is being amplified below through its key properties of characterization, as follows:

1. The Renormalization tendency (RENO):
XF, by having no inner "mechanism" of keeping or constraining its compressed state (see the 2nd FUPON) and thus its acquired compressional energy (called ergoEnergy), will have the natural, inherent tendency of releasing its ergoEnergy and transforming it back into its default XB state. We call that natural tendency of XF its renormalization (RENO) tendency or force R_XF.

  .a) The process or mechanism through which the renormalization tendency of the xenofluid (XF) is implemented or take place is called its inherent dispersive (INDI) mechanism. That INDI mechanism will generate an outward inherent dispersive field called the INDI field.
  .b) The strength of an INDI field is measured through the RENO force of expansion. That outward RENO force is linearly proportional to the xenofluid's density: the greater the density, the greater the magnitude of that force.
  .c) When RENO is not able to manifest its existence in a XF-mass, then that XF-mass is said to be endowed with a resistivity towards further compression called the xenofluid's xenoresistivity (XERE). The locked RENO force is now transformed into xenofluid's resistivity towards further compression called its xenoresist (XERE) force F_R. The strength of the XERE force is the same with the one of the RENO force as the XERE force is the locked-in RENO force.

Fundamental Remark: .For XF to be able to exist, its RENO cannot manifest its existence. For that to happen, an inward compressional external body force must exist capable to exactly counterbalance the xenoresist (XERE) force FR. Thus, when we talk about the XF-state, we always assume of the existence of a counterbalance tendency (TC) able to keep in check its renormalization force (RXF). That is to say, every point of XF must satisfy the equilibrium TC=RXF.

  .d) A XF-mass because of its XERE is said to be endowed (or infused) with compressional energy called ergoEnergy (erE).

2. The Xenoleveling/Ergoleveling Archimedes Principle
The nature of the xenofluid is derived from its capability to satisfy the Equileveling (EQUI) Principle of Nature as described in the Energy section.

By the Archimedes Xenoleveling/Ergoleveling Principle, the ergoSea's natural tendency is to seek to stay in an ergoLevel equilibrium with its objects. The mechanism of implementing this principle, called xenoleveling/ergoleveling, generates the law of behaviour for the xenofluid medium outlined above in the Energy section and stays at foundation in understanding all interactions in Nature --a study that will lead to the formation of the xenofluid's xenodynamics or ergodynamics.

3. In a xenofluid medium, objects can travel freely without opposing any resistance from its xenofluid environment (eXF). The reason for this is that for XF to be able to exist, in each of its points an exact balance must exist between RXF and the counterbalancing tendency (TC), i.e., we have RXF=TC, everywhere. We call that XF inherent characteristic of unresisted opposition to a moving object immersed in XF its xenonull (XENU) property.

Remarks:     j-a). That xenonull property is remarkable indeed, as it signify that any object immersed into XF can move freely within it without encountering any resistivity from its environmental XF, (eXF), provided that the object will not exceed a critical upper limit speed when the object will transform and burst into electromagnetic radiation as noted in the Fundamental Remarks below.    j-b). The famous null result of the Michelson-Morley experiment that forced Physics to take an abrupt turn into abyss and embrace Albert Einstein's irrational approach in explaining Nature, can now be explained with ease, in a rational way, through the discovered xenonull property of XF (XENU).    j-c). Sir Isaac Newton's postulated First Law of Motion (FLOM) stating that "every body continues in its state of rest, or of uniform motion in right line, unless it is compelled to change that state by forces impressed upon it" needs no longer be postulated as that law of motion is a straightforward consequence of the xenonull property of XF. Of course, in a xenovoid environment (eXV), Newton's FLOM is trivial in the sense that is conformed with and derived from our given Common Sense.    jj). The XF-density generates a XF-pressure (called ergoPressure (erP) or energy pressure) that is "felt" by any object imbedded in XF and manifests its existence through the object's acquired interactional properties. The remarkable xenonull property of XF (XENU), notwithstanding XF's pressure on its immersed objects, is that XF opposes no resistance of any sort to the motion of its objects.

4. Two XF-masses in a head-on collision that is powerful enough to be able to overcome the XF's resistivity towards further compression (i.e., to overcome the magnitude of the XERE force) will unite, creating the called power contact (POCO) union. The mass of that union is called the POCO XF-mass.

5. A POCO XF-mass, if left unrestrained --by its renormalization property (RENO)-- will decompress having a tendency to disperse into its xenovoid (XV) environment. The end of that decompression is when it reaches the XB-state. However, when there, the POCO XF-mass will not be reduced to one single XB-block, but to two adjacent XB-blocks that are in contact. We call that XB-block formation, the duobase (DUB).

Remark: .Two colliding XF-masses will not automatically generate a union. For that to happen POCO must take place. And for that, two basic conditions are required to exist: . i) One, with respect to the type of collision itself. Only head-on collisions of two XF-masses will be able of generating POCO in the XV-space. (Any other type of collision that takes place in the XV-space will transmit the bulk of the force of the impact into the resulting motion generated by the impact.) .ii) The other, is with respect to the magnitude of the force of impact that must exceed the existing force of resistance of each of the two colliding XF-masses.

6. Two XF-masses in contact that are commonly shrinking due to the ergoleveling (ELE) will interweave their points, lines, or surfaces of contact generating an indestructible union that result into a new whole XF-mass. We call that integration the conditional xenointegrativity (COXI) property of the xenofluid. It is "conditional" because the integration can occur only if the the ERLE mechanism is present. We refer to the new XF-mass created as the COXI XF-mass.

7. A COXI XF-mass, if left unrestrained, will transform (by the ELE property) into one single mass whose ergoLevel (erL) is zero, i.e., will transform into a XB-mass. We call that the base xenointegrativity (BAXI) property. We call that newly formed XB-mass the BAXI XB-mass.

8. Two XB-masses, upon a collision in the XV-space, will transform --through the compression generated by the inertia of motion (to be described in detail in the next section)-- into two xenofluid (XF) masses that will generate a sure connect (SUCO) formation. The connection is "sure" because there are no conditions imposed on the collision. SUCO will take place regardless how minute a collision may be. We refer to the newly created XF-formation as the SUCO XF-formation and to its mass as the protodense (PD) mass.

9. A SUCO XF-mass, if left unrestrained, will go back (by the RENO property) to the two XB-masses that generate it. We call that the duobase (DUB) return that is the same as in the case of a POCO XF-mass.

Remarks: .   . .a) If left unconstrained, a POCO or a SUCO XF-mass will transform into two adjacent XB-blocks --the DUB formation, while a COXI XF-mass will transform into one single XB-block --the BAXI XB-mass. .b) COXI can be viewed as a interlacing union while the POCO and SUCO can be viewed as an attached (side by side) 2-part union. An object within a POCO or SUCO XF-masses, traveling between one part to the other, will not be hindered in any way as the XF points, lines, or surfaces of contact between the two parts called xenosealants are indistinguishable from the rest of the XF-mass.

III. By the 4th FUPON, XF cannot accommodate an indefinite compression as it will exist a maximum value density, called critical density , beyond which the XF state can no longer sustain compression. The smallest compression of the gel xenofluid (gelofluid) will transform the XF-state into a new sate called the xenorigid (XR) state whose properties of characterization are as follows:

1. A XR surface cannot be permeated by xenofluid (XF). We call this the impermeability (IMPER) property of XR.

Remark: By APER property of xenovoid (XV), it follows that an object whose surface is XR that moves in a xenofluid environment (eXF) medium, it will leave "behind" xenovoid (XV).

2. A XR surface born out of an environmental xenofluid (eXF) medium will rupture its attachment from its eXF. We call that detachment or rupture from its eXF the xenorupture (xeR) property of XR.

Remark: The xenorupture property of XR leads to the same result noted above that an object whose surface is XR as it moves through its eXF will leave "behind" xenovoid (XV).

.		FUNDAMENTAL PROPERTY OF THE OBJECTS OF NATURE:
		No object in Nature embedded in xenofluid can increase its sped indefinitelly.
		As we shall see, the "ultimate" objects (ULOBs) of Nature embedded in xenofluid (XF) have their surfaces made of xenorigid (XR). By the xenorupture (xeR), as an ULOB advances in its environmental xenofluid (eXF) medium, will generate in its frontal part --by impingement-- a stretched concave XF surface in the eXF. With the increase of the speed of ULOB that stretch will increase to a maximum limit until the concave XF-surface transforms into a XB-surface. A XB-wall was created that will crash the moving ULON transforming it into an electromagnetic field radiation spreading on that XB-wall that is perpendicular to the object's direction of motion. Thus, no ULOB can increase its speed indefinitely at it will a exist a critical speed beyond witch a moving ULON will disintegrate transforming into a burst of energy. (That critical speed is function of the xenofluid's density : the greater is , the greater will be.)
		An object reaching its maximum critical speed before transforming into a burst of energy by hitting the xenobase "wall". The energy is released in the form of electromagnetic radiation (light) that is propagating perpendicular (red arrows) to the object's direction of motion.
		Because of the concavity of the XB-wall that is perpendicular to the object's direction of motion, the electromagnetic radiation emanated will follow the curvature of the concavity of the xenobase wall. Thus, the curvature of propagation of the electromagnetic radiation is not due because the space itself has an inherent curvature as currently is being assumed through the nilly-willy postulate in Einstein's General Theory of Relativity, but, as seen, because of entirely different reasons and concepts. Thus, from this analysis, we were able to see not only HOW the electromagnetic propagates, but also WHY it always propagate transversal and not longitudinal and, as well, WHY is having a curvature.
		The role played by the xenobase (XB) state begins to emerge as most fundamental as we begin to "see" things that we could never be able to see before, such as:
		a) WHY objects cannot increase their speed indefinitely in an environmental xenofluid (eXF) medium; or, b) WHY the electromagnetic radiation propagates only transversal and never longitudinal and possess a curvature.

3. A XR-block, up to a finite limit called the fullresist (FURE) limit, cannot be compressed or stretched out (decompressed).

Remark: The value of the FURE limit towards compression need not be the same to the one for decompression. Collectively, the fullresist limit towards compression and the one towards decompression can be incorporated into the allresist (ALRE) concept.

IV. By exerting a force above the XR's allresist limit, XR will disintegrate and pulverize. The pulverization of XR create a "dust" of XR called heavy xenodust (hXD).

Note: Both extreme states of existence of xenosubstance --the xenobase (XB) and xenorigid (XR)-- if subjected to stresses beyond their "material resistivity" will transform respectively into light and heavy xenodust. So we can say that the xenodust (XD) comes in two types or "flavors" --light (lXD) and heavy (hXD). The speculative dark matter employed in nowaday Cosmology is exactly the xenodust introduced herein. So, we can talk about "light" and "heavy" dark matter.

The xenobase with its additional two compressed states have been incorporated into the concept of xenosubstance (XS). Now, the xenodust (XD) needs to be added as well and be viewed as a degenerated state of XS.

The exact mechanisms and situations that will lead to the creation of permanent xenofluid and xenorigid states out of the default xenobase state as well as of the creation of xenodust in the primeval LOON will emerge from the studies of collisions that begins with the next section.
