The mass-energy density of the dominant cosmic constituents averaged over the entire universe is 
Dark energy: Dark matter: Ordinary matter ≈ 68%:27%:5% (1.1)
Dark energy and dark matter has been interpreted to be the positive and negative, respectively, relative energy between the diquark uu and the quark d in the protons in the hydrogen gas permeating the universe . Subsequently , the negative relative energy has been used to account for the galaxy rotation curve instead of the unobserved dark matter. The positive relative energy has been used to account for the acceleratingly expanding universe instead of the unobserved dark energy. Further, by including the negative relative energy, a neutron star with a mass near the Tolman-Oppenheimer-Volkoff limit MTOV ~3 solar masses is prevented from collapsing into a gravitational singularity but becomes a “black neutron star”.
These qualitative results however do not shed any light on the observed ratios in (1.1). The purpose of this paper is to extend  to provide some quantitative estimates on the limits on these ratios (1.1). The proton size is calculated in Section 2. In Section 3, the hydrogen atom structure is illustrated. Section 4 shows the proton structure and estimated upper limits of the ratio “dark matter”/ordinary matter in galaxies. Analogous estimates of “dark energy”/nonrelativistic ordinary matter in a small part of the outer part of the universe are given. In the Appendix, gravitational effects are included. Equations of motion for a diquark are constructed. When combined with the equations of motion for a quark, equations of motion for a diquark-quark baryon obtained earlier are recovered.
2. Proton Wave Functions and Its Size
As in  , the scalar strong interaction hadron theory (SSI)  provides the framework. Parts of Sections 2 - 5 in  are reproduced for use here together with an extension. Let a uu diquark A at xI interact with a d quark B at xII via a scalar interaction VAB(xI, xII). Since the quarks are not observable, introduce the proton coordinate Xp and the relative coordinate x,
where am is an arbitrary real constant. The laboratory coordinate Xp is an observable but x is not but “hidden”. The total proton wave function is of the form [3 (3.2)],
Here, a, run from 1 to 2. In the rest frame considered in , , E0 is the proton mass and −ω0 is the relative energy between uu and d.
Equation (1.3) is governed by the baryon wave equations [3 (2.3)] which contains the derivatives and with respect to xI and xII, respectively, appear. For the present case, these derivatives leads to the same result [3 (5.1)] for
[3 (5.2)]. Since am can range from −∞ to +∞, the relative energy −ω0 can likewise do so. This provides the basis of the results in .
χ0(x) and ψ0(x) in (1.3) have been decomposed into an angular part and a radial part g0(r) and f0(r) in [3 (3.4)]. Here, the diquark-quark distance . g0(r) and f0(r) have been solved and plotted for neutron in Figure 1 in . Since the masses of proton and neutron are almost the same, as do those of the u and d quarks, this plot can be used here. Inspection of this figure led to the estimate that the average which has been employed in [3 Sections 6 and 8].

Xe denotes the electron coordinate in this laboratory frame, Xp that of the proton and XH their center of mass or hydrogen atom. For illustration, the proton-electron mass ratio mp/me has been deliberately lowered to about 2 so that Xe falls within the figure. The diquark uu is at xI and quark d at xII. A “hidden”, relative coordinate system x = xII − xI = (x1, x2, x3) centered at Xp is introduced. denotes the angles in this “hidden” x space and is randomly distributed here.
This ra value may be improved by weighing r with the squares of and and averaging over the relative space. With the plots in , computation yields for the average
3. Hydrogen Atom Structure
The structure of the hydrogen atom in the rest frame in SSI is illustrated in Figure 1.
The electron cloud is symmetrically concentrated within a sphere with Bohr radius a0 ≈ 0.53 Å centered at the center of mass coordinate XH. The associated radial wave functions are
Here, Xe is the actual (not scaled down as is illustrated in Figure 1) electron coordinate in the observable laboratory frame. R00 refers to the ground state and R10 to the first radically excited state.
Accompanying this electron cloud is an associated proton cloud likewise symmetrically distributed around XH. This cloud is analogously concentrated inside a sphere with the proton Bohr radius
The observable mass mp and charge +e of the proton reside in the laboratory frame proton coordinate Xp in Figure 1. The diquark uu and quark d are located at the unobservable coordinates xI and xII, respectively. is the “hidden” unobservable relative space “isolated” from the observable laboratory space X.
4. Upper Limit of Ratio of Dark Matter to Ordinary Matter in Galaxies
In [3 Section 8], dark matter has been used to account for the galaxy rotation curve qualitatively. Defining the ratio of dark energy/ordinary matter to be RDE and dark matter/ordinary matter to be −RDM, (1.1) yields
As the galaxy in Section 3 expands, the hydrogen atom in Figure 1 will move outwards from the galaxy center and becomes far away from it. This has been considered in [3 Section 8]. The constituents of this atom are illustrated in Figure 2.
The outward motion of the atom is due to thermal expansion of the young galaxy containing it and proceeds via Coulomb force between the electrons in the hydrogen gas; the proton gets dragged along. The gravitational pull from matter in the central part of the galaxy on the proton produces a negligible shift of Xp and asymmetry in the proton cloud due to the strong restraining electron-proton Coulomb force. Since the quarks are in the “hidden” relative space and do not interact with the electron in the laboratory space but interact with the ambient gravitational field [3 VBG in (2.1)], [2 end of Section 5], they will be pulled back from Xp by these gravitational forces and lag behind to the left of Xp. Further, the diquark uu at xI is about twice as heavy as the quark d at xII [4 Table 5.2] and will feel twice the gravitational pull and hence lies closer to the galactic center and to the left of xII, also mentioned below (A6).
Since the proton is largely confined inside the proton Bohr sphere, its constituents, the diquark uu at xI and quark d at xII, are likewise confined to the same
Figure 2. It develops to the right part of Figure 3 in . It illustrates the constituents of the hydrogen atom in Figure 1 moved outwards from the galaxy center to a region far from it. The proton Bohr orbit with radius a0p ≈ 28.8 fm corresponds to the electron orbit with the Bohr radius a0 ≈ 0.53 Å in (3.1). Both are centered at the center of mass XH which is also the center of the hydrogen atom. The proton cloud is concentrated inside a sphere of radius a0p. This sphere intersects the Rg axis at XH ± a0p. Here an Xp point to the left of XH is chosen for consideration; the associated Xe lies far to the right and is not shown. The associated diquark uu is located at xI and quark d at xII closer to the galactic center Rg = 0 due to differential gravitational pull.

It illustrates the constituents of the hydrogen atom in Figure 2 moved outwards to an outer region of the universe which is beginning to expand acceleratingly. The horizontal line represents the distance Ru from some unspecified inner region of the universe. The figure has the same form as Figure 2 but with quarks moved to the right side of the proton coordinate Xp. The associated Xe lies far to the left and is not shown.
proton cloud sphere. This provides a limit in Figure 2. The above mentioned symmetry yields an average value . Further, the mean value of in (2.5). Inserting these three relations into (2.1), (2.4) and (4.1) leads to the estimated limit
consistent with the observed average of −5.4 in (4.1) which lies near the middle of the allowed range 0 to −8.4..
5. Ratios of Dark Energy to Nonrelativistic Ordinary Matter in Outer Parts of Universe
As the hydrogen atom in Figure 2 continues to move outwards, it enters the outer regions of the universe, as has been considered in [3 Section 9]. In the beginning of this region, the left part of Figure 4 in  shows that this hydrogen atom, being too far away from the galaxy’s central region, is no longer affected by any gravitational force and reverts from the configuration of Figure 2 back to that in Figure 1. This configuration is unstable with respect to dark energy generated and eventually turns into the configuration on the right part of Figure 4 in  where the quarks in the proton are being pushed outwards acceleratingly by the increasing dark energy generated in this region. The situation is illustrated in Figure 3.
In this region, the protons are expected to move fastly so that the above treatment, valid for rest frame and approximately also for slowly moving protons, no longer holds. The rest frame treatment in [4 Ch.10-12] no longer holds and no result can be reached. However, just before this region is reached, the norelativistic left part of Figure 3 in  is approximately applicable so that a treatment analogous to that in section 4 can be carried out. Applying Figure 3 instead of Figure 2 with the criterion above (4.2) replaced by turns (4.1) to
This disagrees with the observed in (4.1). This is not surprising in view of the consideration above (5.1); (5.1) holds only for slowly moving protons which constitute only a small part of the protons in Figure 3. The bulk of the protons there moves fastly and the rest frame treatment here does not hold.
Appendix. Inclusion of Gravitation and Equation of Motion for Diquark
The theory SSI  underlying the above results does not include gravitation. These results have been obtained by phenomenologically joining gravitation to the baryon sector of SSI. Here, gravitation will be introduced into the equations of motion for quarks, from which a set of somewhat generalized equations of motion for baryons will be constructed. This construction differs somewhat from the one step construction in [4 Ch 9] in that it is divided into two steps. In the first one, equations of motion for diquark are written down. These are then combined with a set of quark equations to form the baryon equations. This is done because diquark plays a decisive role in the above sections.
For the present applications, it is sufficient to introduce a scalar gravitational potential into the quark equations, such VGB(xII) in [3 (2.1)],
Here, G is the gravitational constant, mB the mass of the d quark B and Mg the mass of the galaxy containing quark B. xII is the position of this quark in a coordinate system with its origin at the center of the galaxy denoted by 0 in Figure 2 above. εII is typically a small number of the magnitude of !0−6 in the middle of the Milky Way. The gravitational force on this quark is thus negligible but not relative to that on the accompanying diquark in (A6) below.
The potential (A1) containing mB can be moved to the right side of [3 (2.1)] which now reads
which has the same form as the starting [4 (9.1.2a, 2b)] with mB multiplied by (1 + εII).
Potentials corresponding to (A1) are now introduced into the quark equations [4 (9.1.1, 3)] for quark A at xI and quark C at xIII, respectively. These now read
Following [4 Section 9.2], the V’s on the left sides are moved to the right sides and (A3) and (A4) are multiplied together. While wave functions of three quarks were multiplied together and generalized to baryon wave functions in , only two quarks A and C are involved here. Analogous to [4 (2.2.2)], the diquark wave functions are
Here, quarks A and C belong to the same species and are merged together via and . This leads to . The multiplication and (A5) yields the diquark wave equations
in which products not formimg diquark have been dropped. Equations (A5) has the same form as the meson wave equations [4 (2.3.22)] in which the quark masses are mp+mr in [4 (2.3.27)]. Analogously, the diquark mass here is 2mA. The small gravitational pull on the diquark is thus about twice that on the quark mentioned below (A1). This small difference causes, over long time and large distances, the diquark coordinate xI to lie closer to the galactic center than does the quark coordinate xII in Figure 2, as was mentioned there. How this is accomplished has not been investigated.
The potentials equations [4 (9.1.4a, 4c)] are likewise multiplied together to yield
analogous to [4 (9.2.2, 2.9, 2.11] involving three quarks. The corresponding expression for quark B [4 (9.4.1b)] reads here
Multiplying together the diquark A equations (A6, A7) and the quark B equations (A2), with the potentials V moved to the right side, and generalized the product wave functions to nonseparable baryon wave functions similar to [4 (9.2.12)] leads to
which reduces to the diquark-quark baryon wave equations [4 (9.2.14)] for . The generalization of quark masses in (A9) to internal mass operators [4 (9.3.8, 13, 14)] operating on internal functions [4 (9.3.1)] is unaffected by inclusion of gravitation.
Multiplying together (A7) and (A8) and using the generalization [4 (9.2.2)] reproduces the baryon potential equation [4 (9.2.11)],
