  Previously, we proposed several empirical equations to describe the relationship between an electromagnetic force and the temperature of the cosmic microwave background (CMB).We attempted to justify why our empirical equations cannot be coincidental from the mathematical connections between our three equations. However, there are small errors in our empirical equations, which may lead to “indeed or not” arguments. After evaluating our equations, we discovered a method to improve the accuracy of the numerical calculations. For the value of the CMB, we used 2.72642 K instead of 2.72548 K. Regarding the factor of 9/2, we used 4.48870 instead of 4.5. Regarding the factor of 
  &amp;pi;, we used 3.13189 instead of 3.14159. Then, the error becomes less than 10
  <sup>-5</sup>. This means that our equations cannot be coincidental. Furthermore, we attempt to provide hints on how to construct the background theory.

Introduction</title><p>Our main research explains the current independent constant voltage loss (0.35 V) in Sm doped Ceria (SDC) electrolytes in solid oxide fuel cells (SOFC). This voltage loss cannot be explained by Wagner’s equation. During the oxygen ion hopping conduction with enough electron’s atmosphere, this voltage loss may be explained by Jarzynski’s equality. The discovered equivalent circuit is different from the usual RC circuit, and seems to be useful to explain the gravitational force. Then, we discovered Equations (1)-(3) [<xref ref-type="bibr" rid="scirp.109217-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.109217-ref2">2</xref>] and [<xref ref-type="bibr" rid="scirp.109217-ref3">3</xref>].</p><p>Previously, we reported the empirical equation for a gravitational force in terms of the temperature of the cosmic microwave background (CMB) [<xref ref-type="bibr" rid="scirp.109217-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.109217-ref2">2</xref>]:</p><p>G m p λ p 2 &#215; 1   kg = 9 2 k T c (1)</p><p>where G, m<sub>p</sub>, λ<sub>p</sub>, k, and T<sub>c</sub> are the gravitational constant, the rest mass of a proton, the Compton wavelength, the Boltzmann constant and the temperature of the CMB, respectively.

However, after the discoveries of empirical Equations (2) and (3), we noticed that there were confusions in our definitions between the Gibbs volume entropy and PV (P is pressure and V is volume). To elucidate the equivalent circuit, there need the more difficult thermodynamic concept. So, we abandoned the theoretical explanation for Equations (2) and (3) [<xref ref-type="bibr" rid="scirp.109217-ref3">3</xref>].</p><p>Our conclusion in the previous report was that the mathematical connections among Equations (1)-(3) provide evidence that they are not coincidental [<xref ref-type="bibr" rid="scirp.109217-ref3">3</xref>]. There remain following two main problems in our previous works.</p><p>Problem1: We could not explain three equations theoretically.</p><p>It means that we cannot provide the suitable equivalent circuit in our equations. The equivalent circuit may be different from the usual LRC circuits. There may be the strong combinations with the difficult advanced thermodynamics, which include the inevitable dissipation.</p><p>Problem 2: There are small errors in our empirical equations</p><p>Equations (1)-(3) are not complex and connected each other. But there remains the possibility that the small errors may lead to “indeed or not” arguments.</p><p>In this report, we searched for a compensation method to solve the above Problem 2 and to provide hints to solve Problem 1. The rest of the paper is organized as follows. In Section 2, we present the symbol list, the calculation results for frequently used values and important equations. In Section 3, we present new expressions for Equations (1)-(3). In Section 4, we present the newly discovered empirical equations. In Section 5, we present our compensation methods and the verification of newly discovered empirical equations. In Section 6, we attempt to provide hints on how to construct a background theory.</p></sec><sec id="s2"><title>2.

However, after the discovery of many empirical equations, we strongly feel that X may be separated into electromagnetic potential energy and kinetic energy, including the rest mass energy.</p></sec><sec id="s6_3"><title>6.3. Relationship between G and kT<sub>c</sub></title><p>In our four empirical equations, we used the gravitational constant (G). We noticed that G is not independent of the CMB.

Therefore, the relationship between Hawking radiation and Equation (53) should be examined.</p></sec><sec id="s6_4"><title>6.4. Consideration for the Four Special Lengths</title><p>About for four special lengths (Classical electron radius, Compton wavelength for an electron, Bohr radius and Rydberg constant), the following Equation (56) is well known.</p><p>r e 2 π = α λ e = α 2 a 0 2 π = α 3 1 2 R ∞ (56)</p><p>When π is changed from 3.14159 to 3.13189 in Equation (56), the relationship between four lengths seemed to be changed. But there are no problems. We used Equation (4). For convenience, Equation (4) is rewritten below.</p><p>e 2 4 π ε 0 = ( 1.6022 &#215; 10 − 19 ) 2 4 π &#215; 8.8542 &#215; 10 − 12 = 2.3071 &#215; 10 − 28 ( J ⋅ m ) (57)</p><p>Then, in Equation (57), we used 3.14159 as π.</p><p>r e = e 2 4 π ε 0 1 m e c 2 (58)</p><p>So, the value of r<sub>e</sub> cannot be changed. Consequently, Equation (56) can be unchanged.</p></sec><sec id="s6_5"><title>6.5. Consideration for the Degree of Freedom outside the Lorenz Invariant Scheme</title><p>The factor of 4.5 and π were considered to be related with the degree of freedom inside a proton and an electron [<xref ref-type="bibr" rid="scirp.109217-ref3">3</xref>]. So, our compensations in this report are related with the degree of freedom outside the Lorenz invariant scheme. The degree of freedom inside an electron seems to be 2π. We thought that 2π is related with a spin of electron. Angrick et al. confirmed that the spin of electron cannot be ignored thermodynamically [<xref ref-type="bibr" rid="scirp.109217-ref5">5</xref>]. Furthermore, Aquino et al. discovered the new method for vector analysis [<xref ref-type="bibr" rid="scirp.109217-ref6">6</xref>]. We hope that the degree of freedom outside the Lorenz invariant scheme will be clarified experimentally in detail.</p></sec></sec><sec id="s7"><title>7. Conclusions</title><p>Previously, we discovered an empirical equation (Equation (1)) relating a gravitational force and the CMB [<xref ref-type="bibr" rid="scirp.109217-ref1">1</xref>]. Next, we discovered the empirical equation (Equation (2)) for the ratio between a gravitational force and an electric force. Coulomb’s law with distance can be expressed in terms of the CMB (Equation (3)). Our conclusion was that the mathematical connections among Equations (1)-(3) provide evidence that they are not coincidental [<xref ref-type="bibr" rid="scirp.109217-ref3">3</xref>]. However, there are small errors in our empirical equations, which may lead to “indeed or not” arguments.</p><p>Therefore, we attempted to reduce the errors. For this purpose, we searched for an empirical equation between the remaining mass values of an electron and a proton (Equation (20)). Next, we discovered three empirical equations (Equations ((24), (26) and (27)) with the rest mass of a proton. We then discovered three empirical equations (Equations ((29), (31) and (32)) with the rest mass of an electron.</p><p>Then, we discovered the compensation methods. For the value of the CMB, we used 2.72642 K instead of 2.72548 K. However, we felt that this was not the result of experimental measurement errors. This small deviation may be attributed to unknown theoretical reasons. Regarding the factor of 9/2, we used 4.48870 instead of 4.5. Regarding the factor of π, we used 3.13189 instead of 3.14159. Then, the errors in the seven equations were less than 10<sup>−5</sup>. Therefore, we can justify why the discovered compensation values should not coincide.</p><p>Furthermore, we attempted to provide hints on how to construct a background theory. X in the Jarzynski equality is investigated in quantum physics. X may be separated into electromagnetic potential energy and kinetic energy, including the rest mass energy. We noted that G is not independent of the CMB. Equation (53) is similar with Hawking radiation. Therefore, the relationship between Hawking radiation and Equation (54) should be examined. The relationship between four special lengths can be unchanged. The degree of freedom outside the Lorenz invariant scheme is important to explain our compensations.</p></sec><sec id="s8"><title>Conflicts of Interest</title><p>The author declares no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s9"><title>Cite this paper</title><p>Miyashita, T.
