Self-Similar Symmetry Model and Cosmic Microwave Background

  • Graduate School of Natural Sciences, International Christian University, Tokyo, Japan

In this paper, we present the self-similar symmetry (SSS) model that describes the hierarchical structure of the universe. The model is based on the concept of self-similarity, which explains the symmetry of the cosmic microwave background (CMB). The approximate length and time scales of the six hierarchies of the universe—grand unification, electroweak unification, the atom, the pulsar, the solar system, and the galactic system—are derived from the SSS model. In addition, the model implies that the electron mass and gravitational constant could vary with the CMB radiation temperature.

1. Introduction

What determines the values of the physical constants and whether they will remain constant over time are fundamental questions in physics. A long-standing conundrum associated with the physical constants is that large dimensionless numbers that are seemingly unrelated can be linked by a scale factor of 1039 [15]. The Dirac large numbers hypothesis (LNH) tackles this problem. It claims that the gravitational constant G is inversely proportional to the age of the universe. The LNH is based on the coincidences between three very large dimensionless numbers N1N2N. N1, the ratio of the radius of the observable universe to the radius of the electron, is approximately 1039; N2, the ratio of the electromagnetic and gravitational forces between a proton and an electron, is also approximately 1039; and N, the number of protons in the observable universe, is approximately 1078. The Dirac LNH argues that “any two of the very large dimensionless numbers occurring in Nature are connected by a simple mathematical relation, in which the coefficients are of the order of unity”[1].

In this paper, we present the self-similar symmetry (SSS) model in which the relationships among these seemingly unrelated physical quantities are represented using a simple geometric sequence for which the first term and the geometric ratio are given by dimensionless ratios of masses. Based on the LNH, the first term of the geometric sequence corresponds to the cosmic microwave background (CMB) radiation temperature, which points to the possibility that the values of the physical constants are determined by the CMB radiation temperature.

2. The Self-Similar Symmetry Model

In the SSS model, the CMB has a symmetrical self-similar structure and the physical constants are dimensionless, otherwise they would not have universality. Therefore, the fundamental dimensionless mass ratios are defined as follows:

A=logα=log(mplmpr),B=logβ=log(mempr),    (1)

where mpr is the proton mass, me is the electron mass, and mpl is the Planck mass, and the fundamental dimensionless time and length ratios are defined as

T=log(ttpl),L=log(llpl),    (2)

where t and l are the time and length scales of the hierarchies and tpl and lpl are the Planck time and Planck length, respectively. The similarity dimension D is defined using these dimensionless parameters:

D=(TL)3=AA+B1.206.    (3)

We then assume that hierarchical structures are constructed according to the following sequences:

L0=2(A+B)31.701,    (4)
Ln=DnL0        for   L>L0,    (5)
Lm=(2-Dm)L0   for   L<L0,    (6)

where n and m are natural numbers that represent the hierarchical level. In addition, the time scales of each hierarchy are calculated using Equation (3).

3. Verification of the SSS Model

To verify the SSS model, we compared values obtained with it against reference values. Tables 1, 2 summarize the length and time scales, respectively, of the grand unification, electroweak unification, atom, pulsar, solar system, and galactic system hierarchies of the universe. The SSS model values agree well with the reference values. Figure 1 shows the hierarchy time scale as a function of the length scale. The coincidences in the figure confirm the validity of the SSS model.

Figure 1. Time scale as a function of the length scale for the SSS model and reference values. The gradient of the fit of the SSS model values to the reference values is 1.0729(R2 = 0.9991). Note the symmetry about the first term L0, which corresponds to the CMB radiation temperature. This symmetry leads to speculation about the approximate length and time scale of the universe, which are 4.1 × 1028 m and 5.2 × 1016 years, respectively.

4. Discussion

From Equation (1), 2A = −logαG, where αG=Gmpr2/c is the gravitational coupling constant, the following coincidences occurs:

Ln=2-Lm=3=Ln=3-Lm=22A.    (7)

Equation (7) shows that αG plays an important role in forming the hierarchical structure of the universe. In addition,

Lm=1-L0=L0-Ln=1=2B.    (8)

Thus, if Lu is the length of the universe, the following hierarchy holds:

Lu=2L0.    (9)

Therefore, the ratios of the coincidences between the length scales of the hierarchies are

ra=Ln=2-Lm=3Ln=11.002,    (10)
rb=Lu-Ln=3Ln=2-Ln=10.991,    (11)

from which we get

D=ra-rb1-rb.    (12)

From Equation (12), we see that rarb ≠ 1.

With respect to the first term of the geometric sequence, L0, we find that

(αβ)-2Tpl2.821K,    (13)

where Tpl is the Planck temperature. The value in Equation (13) is consistent with the CMB radiation temperature TCMB[11]. Assuming the right-hand side of Equation (13) represents the TCMB, if LNH is applied to Equation (13) and we define the dimensionless temperature ratio τCMB = TCMB/Tpl, we get

αGτCMBD.      (14)

Similarly,

  β2τCMBD-1.      (15)

Thus, both αG and β are power functions of TCMB.

Substituting TCMB = Tpl, an initial condition of the universe, into Equations (14) and (15) yields α = β = 1, which means that the entire hierarchy was contained in a single point and that the electron, proton, and Planck masses were equivalent. These masses have varied since that initial single point such that memprmpl, in response to the changing TCMB, where TCMBTpl. Assuming that TCMB → 0 is the ultimate fate of the universe, then α → ∞, β → 0, and L0 → ∞, indicating that me → 0 and G → 0 as the universe expands to infinity.

5. Conclusions

Our SSS model describes the large-scale structure of the universe and shows that the six hierarchies of the universe are self-similar to the CMB, indicating that the CMB is key to unifying quantum theory with general relativity. In addition, the SSS model leads to the conclusion that me and G vary with TCMB. Any errors arising from the SSS model are problems to be tackled in the future.
