The Cause of Gravity


1. Introduction

Isaac Newton said that gravity is proportional to mass, (1) and Albert Einstein showed that the gravity is expressed through the curvature of space. (2) Although these were both important advances in our understanding of gravity, neither one addresses the cause of gravity. This article therefore proposes to identify what causes the curving of space-time which is the expression of gravity, and to incorporate gravity into a unified equation with matter and energy.

In his discussion about general relativity, Einstein said that gravity is the same as any other acceleration, except that gravity's acceleration is caused by the curving of space. (2) And this acceleration which is proportional to mass, of course implies that there is a force at work. But it is obvious that mass is not a force. So mass can not perform the work of warping space, and therefore mass itself cannot possible cause gravity. However, since mass is proportional to gravity, and almost all mass is located in the atomic nucleus, the search for the force which warps space and therefore causes gravity, must begin within the nucleus of atoms.

2. The Strong Force

According to the Standard Model, protons and neutrons are each composed of three quarks which are bound together by the strong nuclear force, and it is the strong force which is therefore thought to provide matter with most of its mass. (3,5,9) So the strong force is proportional to mass, and mass is known to be proportional to gravity. And this means that the strong force is also proportional to gravity.

Each atomic nucleus contains about 99.97 percent of the mass of the atom, so they certainly contain most of the mass of matter. But the nucleus is 100,000 times smaller than the diameter of the atom. (3) So it appears to be incongruously small for most of the mass of matter to be found there. Since the strong force interacting with the electromagnetic force should have the capability of imparting movements of near the speed of light, and the strong force is also thought to impart most of the mass to nucleons, and since velocity near the speed of light can cause both an increase in mass and a contraction of dimensions, then it seems probable that all of these attributes are related. The strong force exerted between quarks and nucleons, would thus appear to be caused by relativistic effects which are comparable to velocities near the speed of light, which increases mass and decreases or contracts the spatial dimensions of the atomic nucleus. And these effects would be enacted through relativistic effects causing the formation of virtual gluons, which are the exchanging particles through which quarks and nucleons interact.

Since all of space is interconnected, this slight contraction of space within the nucleus, would spread out within the volume of the atom. And since the nuclear diameter is so much smaller than the atomic diameter, this contraction of the nuclear volume would be diluted within the atom by its much larger volume, and then would be radiated into the space surrounding the atom. And as Einstein explained, gravity is expressed in the curvature of space. (2) So the strong force acting on quarks and nucleons, results in a relativistic mass increase and a comparable dimensional contraction, which is radiated into space surrounding the atom. But the insulating effects of the atomic volume would reduce this effect by the time it could reach other atomic nuclei. This is similar to the effect of the volume of the Earth, which effectively reduces the force of gravity on a person at its surface due to the distance the volume imposes from its center of gravity. And so this effect of an atom's volume insulating the effect of contracting nuclei on each other, would dilute the curvature of space, and would be the effect we know as gravity.

If this is true, it would explain why gravity is proportional to mass, because the mass of atoms and the contraction of space producing gravity would both be relativistic effects within the atomic nucleus. And it would also explain why gravity is so weak, because its effect would be due to a contraction of the tiny atomic nucleus, which is further reduced by the relatively large volume of the atom. And so the reason why matter has to accumulate in such large amounts before the effect of gravity is noticeable, would be due to the relatively small size of the nuclear contraction, and the relatively large volume of atoms which keeps nuclei from interacting more directly.

If gravity is the end result of relativistic effects of repetitive oscillations brought about by the strong force in nucleons, then gravity would not be a separate force of nature as has been supposed. And since it would be the indirect effect of another force, gravity would be expressed only as an indirect field effect, and thus would have no quantum effect of its own. So there would be no separate particle of interaction which carries gravity. And so, there would be no gravitons, because gravity would be only a curvature of space comparable to the relativistic effects of motion. And this would certainly explain why no gravitons have ever been found.

Velocity that is a significant fraction of the speed of light, whether linear, rotational or some combination, must increase mass. Einstein gave the equation for this increase as :
M = Mo/ (1-V^2/C^2) (13) E1
where Mo is the initial mass, V is velocity, C is the speed of light, and M is the amount to which mass has been increased by the relativistic speed. (2) And space is inversely proportional to relativistic velocity, as :
1/D = (1-V^2/C^2) E2
where D represents the dimensions. (2) Relativistic force must therefore cause an increase in mass and also a comparable decrease in the spatial dimensions. And we know that gravity is proportional to mass, so that when mass is increased, gravity must also be increased. Therefore relativistic force which causes both an increase in mass and a contraction of space, would also an increase in gravity, no matter what its cause. And it is therefore probable that these phenomena of the relativistic effects of force increasing mass, contracting space, and causing gravity, are all inter-related as one process.

Even though changes due to relativity are necessarily only relative, these are still very real and observable changes which have been thoroughly validated. Such intrinsic characteristics as the rate of atomic oscillations, the decay rate of particles, and the frequency of light, have all been shown to be changed by the relativistic effects of velocity, and they are changed in exactly the same ways by gravity. (1,2,7) So the effects of gravity can be seen to be comparable to the effects of relativistic velocity. And this is due to the fact that gravity is an acceleration like any other acceleration, but gravity causes these relativistic changes without imparting velocities near the speed of light, and even causes these relativistic changes when imparting zero velocity (in stationary bodies).

Gravity itself should therefore have relativistic origins. And since gravity and mass are proportional, then they could both have similar origins. And since the strong force is thought to be responsible for most of the mass, and gravity is proportional to mass, the relativistic effects in nucleons caused by the strong force must be responsible for the formation of both mass and gravity, whether it imparts relativistic motion directly, or whether this has an indirect cause. Either way, the interaction of the strong force between quarks and nucleons, by producing gluon particles, provides the link between the relativistic formation of most mass, and the relativistic curvature of space which is gravity.

Two unlike electromagnetic charges attract each other, having lines of force which converge, while two like electromagnetic charges repel each other, having lines of force which diverge. (5) If gravity were actually an attractive force, it seems likely that its lines of force should converge like the attractive force of unlike electromagnetic charges. But they do not. Similarly, there are ways to shield against the force of electromagnetism, while there is no known method to shield against gravity. And this lack of shieldability as well as gravity's straight lines of force, are exactly how gravity would behave if it is only a relativistic dimensional contraction surrounding matter. Besides which, gravitons have never been found. So all of these facts are consistent with the supposition that gravity is an indirect result of relativistic dimensional contraction, and are therefore also consistent with gravity not being a separate force of nature.

3. Gravity and the Strong Force

The strong force is unusual in that it is weak when quarks are close together, but increases dramatically as the quarks move away from each other, with the quarks in nucleons interacting through a virtual cloud of gluons. (3) And in each nucleon there are two quarks of like charge, and one of unlike charge. (3) So this combination of loose binding at close quarters, the stronger binding at more distance, and the oppositely charged quarks, should allow quarks within each proton and neutron to move toward each other due to the attraction of unlike charges, and away from each other due to the repulsion of like charges. And this would cause changes in the effective strength of the strong force between the various moving quarks. So that their combined movements would contain various repeated movements or oscillations.

Most nuclei contain nucleon pairs of one proton and one neutron. And each partner of a nucleon pair is composed of oppositely charged quarks, while each also is supposed to have an opposite spin compared to its partner. (4) And so the attributes of the variable strength of the strong force, the opposite charges of quarks, and the complimentarily charges of the quarks within protons and neutrons, should encourage the opposite spins each nucleon partner is thought to have.

Of particular interest in nucleon pairs, is that each of the partners is composed of two quarks of one kind of charge and one quark of the other kind of charge. And the other partner has a set of the oppositely charged quarks. So they are each unbalanced in both charge number and in the volume occupied by the opposite charges. This means that regardless of their overall charge, both protons and neutrons should be polar. And since partners of a nucleon pair are both spinning, they should then each produce magnetic fields, which has indeed been observed for both particles. (5) And since these charges and thus the magnetic fields associated with each particle are unbalanced, one magnetic field will be stronger than the other, with its opposite having unbalanced magnetic fields of the opposite type. So the oscillations of the quarks within a nucleon pair would result in two magnetic fields of alternating strength and alternating charge. And these alternating magnetic fields should therefore amplify the movements.

4. The Relativity of Speed

Since the strong force is the strongest force in nature, its large and variable strength in combination with the oppositely charged quarks within nucleons and their alternating magnetic fields, should be sufficient to supply the power movements comparable to the speed of light for such particles. Einstein said that high rates of motion increase the mass and decrease the dimensions of a moving object, so that at a significant percentage of the speed of light, the object would significantly increase in mass and decrease in size. (2) But actually moving at the speed of light causes an object with mass to develop infinite mass, so that anything with mass would never be able to move at the speed of light. (2) Small objects like subatomic particles however, can move at speeds near to the speed of light. And when they do, their speed causes them to increase in mass, and to decrease in size.

It might be considered to be impossible for nuclear particles to have a rate of motion near to the speed of light, because sub-atomic particles have specific quantum spin components. Since all of the particles which make up atoms are fermions, they should each have half-spin components. (1) However, experiments have shown that quarks appear to exist as points or single dimensional entities within nucleons, similar to electrons, (5) so the quarks that comprise protons and neutrons are most probably the fundamental particles of hadrons.

Quarks then would appear to be the entities which carry the half-spin component usually attributed to protons and neutrons, especially since there are always an uneven number of particles which make up protons and neutrons, even when the other components of nucleons are considered, such as electrons and neutrinos. And this means that protons and neutrons are not really particles at all, but are rather composite systems composed of smaller moving parts, and which have differing internal charges similar to atoms. Atoms are not considered to have quantum spin components of their own. And since quarks can supply the required half-spin component, nucleons could be considered to have movements of their own separate from a quantum spin component. And so the oscillations of quarks relative to each other could be considered as the composite movements of nucleons, or the overall movement of the nucleons themselves.

The strong force interacting with the electromagnetic force would therefore provide the energy for the oscillations of quarks with in nucleons, and these movements of nucleons could be comparable to relativistic velocities, since nucleons could have angular momentums separate from the quantum spin components. This scenario therefore provides a possible mechanism for the strong force to be the cause of gravity.

5. Developing a Unifying Equation

Salam and Weinberg have shown that electromagnetism is related to the weak force, and so together they should both be considered as components of the combined electroweak force. (3, 4) And since gravity is not itself a separate force, this leaves only the electroweak force and the strong nuclear force as the two forces of nature. So this new interpretation of gravity combined with the Salam-Weinberg theory, allows for a new understanding of energy in general. As discussed earlier, the strong force probably interacts with the electroweak force and thus causes most of mass and also gravity in atoms through relativistic effects. And since atoms make up matter, and matter and energy are interchangeable, (2) it is then possible for the major aspects of nature to be unified into one equation.

Einstein related energy E and mass M by the speed of light C in his equation of :
E = MC^2 . E3
And in his discussion of general relativity, he stated that the dimensions are inextricably related to mass. (2,8) And since mass is present in his equation (2), then dimensions must be assumed to be present. Einstein also showed that the spatial dimensions react oppositely to mass in respect to relativistic effects as seen in equations E1 and E2. (2) So dimensions can be added as the compliment to mass as M/D. And thus, equation E3 becomes :
E = MC^2/D . E4

Since gravity is here assumed to not be a separate force of nature, energy E should be composed of only the electroweak force Eew, and the strong force Esf. And if a proton's quarks could be isolated, they are thought to account for about 1.33 percent of a proton's mass, at a average value of 12.5 MeV (from a range of 6 to 19 MeV). (10) So the difference between the mass of the quarks of a proton and the mass of a proton, is the amount of mass which is theoretically attributable to the strong force through the accumulation and interaction of gluons. This means that the strong force carried by gluons would increase the mass of protons from 12.5 MeV to 938.28 MeV, which is a 75.0624 fold increase. The effect of the strong force which is comparable to the relativistic effect of velocity, would therefore cause an increase in mass and a contraction of the spatial dimensions of about 75 fold, which is a reduction to about 1.33 percent of their former size.

Einstein gave the equation governing the contraction of space due to relativistic effects as :
1/D = (1-V^2/C^2) (2) . E2
And by inserting 75.0624 as the value of D, it is evident that gravity as a spatial contraction is caused by a relativistic effect comparable to about 99.99 percent of the speed of light. And it would be this effect which causes the approximately 75 fold increase in nuclear mass which is most of the mass of atoms, and also causes the dimensions of the nucleus to be reduced by the same 75 fold.

So equation E2 can be substituted for D in equation E4 or E5, revealing the relativistic origins of mass and gravity :
E = MpC^2/D . E5
And this equation E5 shows that if nucleons are acted upon by the strong force imparting motion which is comparable to a velocity of about 99.99 C, it causes a dimensional contraction of D = (1-V2/C2) to about 1.33 percent of their former volume, increasing the mass of the fundamental particles Mp to :
M = Mp/ (1-V^2/C^2) E6
The total quark mass of protons Mp at 12.5 divided by 0.01332 thus equals the observed mass of protons M, at 938.28 MeV.

Concurrently, since the dimensions are composed of space and time, with space S reacting oppositely to time as far as relativistic effects are concerned, the relativistic effects on space S and time T would be :
1/D = T/S = T/S (1-V^2/C^2) E7
which would expand the duration of the time dimension, causing it to slow by about 75 fold. But space consists of three dimensions, which is volume. And since helium has two nucleon pairs, its volume of 10^-13 cm is reduced by about 75 fold. And since the volume of an atomic nucleus compared to the volume of an atom are each proportional to the number of nucleons it contains, this percentage remains essentially constant for all elements. (5) And so a relativistic contraction of the atomic nucleus would always be reduced by the same proportion in all atoms. Therefore, the increase in mass of atoms due to the strong force would always be proportional to the size of the dimensional contraction of their nuclei, no matter what its composition. And this is why gravity is observed to be unaffected by the composition of matter which causes the gravity.

6. Einstein's Equation for Gravity

In his equation for gravity :
Gab = (8 G/C^2) Tab E8
Einstein related his tensor for space-time curvature Gab, to the momentum-energy tensor Tab, by 8 G/C^2. So the factor which relates momentum and the curvature of space-time, is 8 times Newton's gravitational constant G divided by the speed of light squared C^2.

In another of his equations :
Re =GM/3C^2 E9
Einstein shows that the excess radius Re of spatial curvature is related to Newton's gravitational constant G, times M as momentum times the formula for the volume of a sphere, divided by 3, and divided by the speed of light squared. So equation E8 and E9 both concern the curvature of space-time, and they both contain G divided by C^2, as well as momentum in the two factors of M and Tab. But they differ by a factor of 3 times 8 , or 24 , and 24 equals 75.3982. So the factor of D in the unified equation E4 can be compared to Einstein's gravitational equation E8 where D equals 75.0624, and 24 equals 75.3982. It is therefore obvious that these numbers are almost equal, being different by less than half of one percent. The factor of 8  in Einstein's equation is therefore comparable to the relativistic mass increase of the fundamental particles, where D equaling 75.0624 compares to 24 , and D/3 equaling 25.0208, compares to 8 .

Since the factor of D is an average and an approximation, while 8 is absolute, 8 is taken to be the correct number. And D is therefore set as being equal to 8 . So the factor for dimensional contraction D equaling (1/C^2/V^2) and divided by 3, and can be substituted for 8 in Einstein's equation for gravity (8), which then becomes :
Gab =DG/3C^2 Tab . E10
And this revised equation E10 then embodies the new concept of the gravitational constant D, being equal to (1-V^2/C^2) as the relativistic contraction of space-time due to gravity. And D also equals 8 which equals 25.1327, thus revealing the relativistic origins of both 8 and D, and also of gravity.

So the revised equation E10 then basically states that dimensional curvature is related to momentum and therefore mass, by the relativistic gravitational factor of D/3 times Newton's gravitational constant, divided by the speed of light squared. And the effect in nucleons comparable to relativistic velocity which results in a contraction of the spatial dimensions of D = (1-V^2/C^2) at a velocity V comparable to 99.99 percent of the speed of light, means that equations E8 and E10 are equal, and therefore would still allow the revised equation to operate just as Einstein had intended. But it also provides the additional information that 8 equals D/3, as the relativistic origins of both 8 and D, and therefore of gravity. And since the factor of D causes the mass of the fundamental particles to be increased by 75.3982 fold, this shows that the quarks of a proton must have an original total mass of 12.4443, which is less than half of one percent different than the recently derived average value of the total mass of a proton's quarks. (10)

This new theory for gravity can therefore be merged with Einstein's equation relating matter and energy E3, to develop a general unified equation E4, which includes the major facets of nature as energy in the form of the electroweak and the strong forces, matter as leptons and hadrons, and the contraction of the dimensions as gravity as the factor D. And Einstein's equation for the relativistic effect of velocity on dimensions E2, with an effect comparable to a velocity V of 99.99 percent of the speed of light C, thus causes a contraction of the spatial dimensions of D = 75.3982, and D/3 = 25.1327, as the cause of gravity. But the factor D may allow for a better understanding of the basis for gravity, since the new gravitational factor of D/3 equaling 8 in equation E10, reveals the relativistic origins of gravity, since gravity has been shown to be comparable to a relativistic effect. Thus, gravity which has appeared to be a direct accelerative force, is shown instead to have an indirect cause, and therefore must act entirely passively, causing a body of matter to merely follow the path of least resistance which is a straight line in curved space-time.

7. The Gravity of Fundamental Particles

In his discussion of general relativity, Einstein observed that electrons produce a small amount of gravity of their own, (2) which is another way of saying that anything with mass produces gravity proportional to its mass. (1,2) However, since the initial mass of electrons is small, and since their mass is not effected by the strong force, and also since their average velocity in atoms is estimated to normally be about 10^-6 ms^-1, (9) there would be almost no change in their mass due to relativistic effects.

Since the strong force is generally considered to increase the mass of quarks, and this increase has here been calculated to be at about 75.3982 fold, then the original mass of quarks in protons would be 12.4443 MeV. And if protons and neutrons have essentially the same forces acting upon them, their quarks would increase comparably due to these same relativistic effects. Neutrons would thus seem to have an original mass of around 12.4614 MeV. And so, the basic concept of the quarks of protons and neutrons supplying an initial combined mass of about 24.9057 MeV, with the strong force multiplying the mass of quarks by 75.3982 fold, by creation of virtual gluon clouds to obtain the observed mass of nucleons, and this mass of 1,878.845 MeV plus the mass of an electron at 0.511 MeV equaling 1,878.356 MeV, therefore seems to be in good agreement with experimental results as well as our general understanding of nature. And therefore about 1.356 percent of gravity would be produced by the fundamental particles, and the balance would be produced by the relativistic effects of the strong force increasing the mass of quarks in nucleons.

The unified equations E4 and E5 in the previous section however, incorrectly portrays relativistic effects as increasing the mass of all fundamental particles. So these equations must be revised in order to separate leptons from hadrons, since leptons are generally accepted as not being effected by the strong force. (1) The unified equation should therefore be revised to read :
E = (Ml+Mh/D) C^2 E11
which then would correctly show that the increase of mass due to the strong force acts only on quarks in hadrons, whose mass would then be added to the mass of the unaffected leptons, to equal the total observed mass of electrons plus nucleons. And further, since neutrons can be formed by a proton's up quark combining with an electron and an antineutrino to form a down quark, (9) then the neutron's mass would change by only about 0.511, equaling 12.9553 (or possibly less, if an antineutrino essentially has an anti-mass). And this is closer to the value calculated above, than the value which has been obtained experimentally. (10) So the masses of up and down quarks may be more similar than has been presumed. At any rate, if an up quark is comparable to a down quark plus an electron and an antineutrino, then this would be consistent with the conservation of electrical charge, and a set of an electron, a proton and a neutron would therefore be comparable to four negative charges in four electrons, and four positive charges in six up quarks. This would also mean that leptons would basically be negatively charged, and up quarks as the fundamental particles of hadrons are positively charged. And this could also explain why the strong force acts only on hadrons, since it would be an attribute of positively charged particles with an effect only over very short distances. And so the strong force could only effect leptons if they are close by, as when they are absorbed to change a proton to a neutron.

8. Gravity in the Early Universe

It is the general consensus that at the beginning of the universe, only pure energy existed, and then during the first fraction of a second of the universe's expansion, fundamental particles are thought to have come into being. (6,11) And these were followed quickly by the formation of protons and neutrons, and then much later were followed by the formation of atoms. (6,11) But if gravity is basically caused by relativistic increases in the mass of nucleons, then at the beginning of the universe when there was no matter, there would have been little or no gravity. And slightly later when there were only fundamental particles, there still would have only been about 1.33 percent of the present mass of matter, since the fundamental particles account for only this amount of matter's mass. And so, fundamental particles would still have produced very little gravity. Not until about 10-3 second when nucleons had formed, (6,11) would gravity have increased to its present strength. And this means that at the beginning of the universe during its initial inflationary period, there would have been very little gravity to slow down its expansion, since protons and neutrons would not yet have come into being.

Until now, a simple explanation for the initial inflationary period of the universe's expansion has been lacking. But the absence of nuclear particles would have meant that fundamental particles would initially have produced very little gravity when the universe was just beginning to expand. So this would provide a simple mechanism for an inflationary period which is thought to have occurred approximately during the first second of the early universe. And if most mass and therefore most gravity is produced as a by-product of the strong force's relativistic effect on protons and neutrons, then protons and neutrons would have to come into existence before much gravity was available to slow down the expansion of the early universe.

And this would then explain why the universe had an inflationary period during which its diameter could have expanded up to about 300 kilometers (at the speed of light) from time zero to about 10^-3 second of its early history, before the full effect of gravity started slowing down its expansion. And since gravity would not have been produced in substantial amounts until after the formation of nucleons, this scenario also supplies a mechanism for the early inflationary period to end, and for the universe to then begin slowly reducing the expansion rate to that which is observed today. Other hypotheses for overcoming the gravity supposed to have existed in the early universe have been proposed. But given an initial state of rapid expansion which is usually assumed for the beginning of the universe, a natural lack of gravity renders these other explanations unnecessary and overly complicated, since a lack of gravity in the early universe can provide a simple solution for the period of inflation which is generally accepted to have occurred in the early universe.

9. Conclusions

This theory of gravity proposes that the unique characteristics of the strong nuclear force are comparable to a relativistic effect of motion near the speed of light, causing an increase in mass and a reduction of spatial dimensions within the atomic nucleus. And each atomic nucleus being separated by the relatively large empty space within atoms, would then cause the contraction of the nucleus to be reduced before it can effect other matter. And a collection of matter with each nucleon causing a slight contraction of space, would produce an effect which would be additive and therefore would be proportional to the amount of mass present, and would also be inversely proportional to distance. This spatial contraction of nucleons would therefore be the cause of the curvature of space which has been identified as the effect of gravity, and is known to be additive, proportional to the mass, and inversely proportional to the distance between gravitational bodies.

The effects of gravity are at any rate comparable to relativistic effects on such things as the wavelength of electromagnetic radiation, nuclear decay, and time dilation, even when gravity does not produce sufficient velocities to directly cause such effects. And so gravity must therefore have relativistic origins. And the strong force is certainly strong enough to cause relativistic contractions, and thus cause the curvature of space within atomic nuclei, which would then expand into the space outside of each atom. And since atomic nuclei are normally isolated by the relatively large volume of the atom compared to the nucleus, this indirectly cause the effect of gravity, which would therefore necessarily be observed as being relatively weak.

So gravity would be entirely a field effect of interacting atoms and/or accumulations of atoms, with the curvature of space acting as both the effect and the intermediary. And gravity therefore can not be considered to be a true force of nature, since it would not be transferred by quantum particles as are the electroweak and the strong forces. But rather the strong force would act directly to relativistically increase mass and contract space-time, which would then act upon other matter through the intermediary of curved space-time, with the overall effect of gravity being passive and indirect. So gravitons which had been supposed to exist, then would of course not exist, nor would there be any quantum gravity as such. And this would explain why gravitons have never been observed, and would also explain how Einstein's theory of general relativity has seemed to explain gravity without considering any quantum effects, because it is correct in explaining gravity as only being a field effect. And the breakdown of general relativity under extreme conditions such as in black holes, does not invalidate general relativity per se, since none of the behaviors of matter are really understood under these extreme conditions.

10. Summary

The new theory therefore proposes the following :

1) Gravity is due to the relativistic effects of the strong force causing increases in mass and a comparable contraction of space in the atomic nucleus, diluted by the greater atomic volume. And this is why Newton could show that gravity is proportional to mass, it is why Einstein could show that gravity is equivelent to the curvature of space-time, and it is also why gravity causes relativistic effects without imparting relativistic speeds, since these all have as their basis, the relativistic effects produced by the strong force in nucleons,

2) The effects of the strong force are comparable to relativistic velocity at 99.99 percent of the speed of light, which increases the mass of quarks by a factor of 75.3982 by producing clouds of virtual gluons, and thus providing about 98.7 percent of mass to matter.

3) Matter consists of electrons as the negative fundamental particles of leptons, and up quarks as the positive fundamental particles of hadrons, with an electrical charge of +2/3, and an original mass of 12.4443 MeV for the quarks in protons. And since the strong force is carried by these positively charged fundamental particles and effects of the strong force are confined to very short distances, electrons are not effected by the strong force, and so their masses are not increased in this manner.

4) And since gravity is an indirect effect of the strong force, and is therefore not a separate force, energy consists only of the electroweak force and the strong force.

5) Einstein's equations E2 and E3 can therefore be combined with the concepts of this theory, to form the following unified equation :
E = (Ml+Mh/D) C^2 E11
where E equals the electroweak and the strong forces, Ml equals the mass of leptons, Mh equals the mass of the fundamental up quark particles of hadrons, and D is the relativistic factor for gravity equaling :
1/D = (1-V^2/C^2) . E2

6) Einstein's equation for gravity can also be revised as :
Gab = (DG/3C^2) Tab . E10
And since D equals 24 and 75.3982, and since D/3 equals 8 and 25.1327, D/3 exchanged for 8 does not change Einstein's equation for gravity, except to reveal the relativistic origins of the factor 8 , and of gravity.

7) This understanding of gravity being the result of the small initial mass of quarks being multiplied by the effect of the strong force which is comparable to relativistic velocity in nucleons, also suggests that the early universe would have had very little gravity before the formation of fundamental particles and nuclei. And this provides a simple explanation for the inflationary period in the early universe, which would have occurred due to the absence of gravity, and which would have ceased when most of gravity later came into being with the condensation of energy into protons and neutrons.

8) This theory proposes that gravity is caused by effects of the strong force comparable to relativistic velocity. And it therefore predicts that the correct mass for the quarks in protons, is 12.444325 MeV. And since gravity is not a separate force, the theory predicts that gravitons will never be found, since they do not exist. And since gravity has relativistic origins, gravity should paradoxically cause relativistic effects without causing relativistic velocities, and should even cause relativistic effects in objects which have zero velocity in gravitational fields. It is therefore significant that all of these predictions are consistent with observations of nature, and also with experimental findings, at this time.
