According to Einstein's theories, what is the smallest particle in the universe? Are vacuum and vibration smaller than atoms? Is there a connection between matter and energy in the quantum world?
In this work, we distinguish the massless (R :$; Rpl ) and the massive (R ~ R pl ) universe and anti-universe, where Rpl is the distance of the Planck length. We have introduced these massless universes because their massless photons which are in thermal equilibrium with the particles, define originally their radiation energy density, so that it must be identical with their particle energy density and vacuum energy density, i.e. these massless universes contain also correspondingly massive (anti}matter. In contrast to these massless universes, the massive universe and anti-universe are characterized by identical radiation density and particle density, which however dominate the vacuum energy density, so that it can be neglected at the description of the massive universes except at the present, accelerated expansion and the final state of the massive universes. The massless universes are described by the gravitation in this work, whereas the massive universes are defined by a new inflation model [1-3] and the Friedmann-Lemaitre Equations [1-10]. In work [1], we have derived the vacuum energy density for R = Rpl via a new inflation model [1-3] defined by the supersymmetric grand unification particles (X and Y gauge bosons [3] as well as magnetic monopoles [3]) in the massive universe (R ~ Rpl ). In the present work, for R = Rpl , we find the same value by a new expression for this vacuum energy density via a new, modified, quantum-statistical photon energy density. This new expression can be generalized for R ~ Rpl • Using this new expression at R = Rpl , for the massless universes (R:$; Rpl ), we find a general vacuum energy density derived by aid of the gravitation. The works [1-3] show that the massive universe is completely described via the new inflation model [~-3] and the Friedmann-Lemaitre Equations [1-10] for Euclidian geometry [1-3] by the present, cosmological parameter values [1-10], which were also exactly estimated in Refs. [1, 2] via the light neutrino density parameters [1-3], multiplied by the different ratios of the relativistic energy and the rest energy of the supersymmetric grand unification particles [1-3]. On this way, because of the known, general properties of particles and antiparticles, in the present work, for the massive anti-universe (R ;::: Rp1 ), we can derive also the present, cosmological parameter values similar as at the massive universe if we use the antiparticles of the light neutrinos and the supersymmetric grand unification particles. Therefore, we assume that the massive anti-universe is also described completely as the massive universe [1-3] if we determine the necessary quantities of the Friedmann-Lemaitre Equations for the massive anti-universe on the basis of the general properties of particles and antiparticles. Thus, because of the time-symmetry of the solutions of the Friedmann-Lemaitre equations, these massive universes must expand in opposite directions, i.e. separation of matter and antimatter. This result is supported by following considerations. From the big bang, the momentary formation of the massless universe and anti-universe, which expand in opposite directions, leads to a separation of the virtual particleantiparticle pairs of the quantum vacuum into real particle (matter) and antiparticle (antimatter) via the gravitational interaction, whereat these separated particles and antiparticles are in thermal equilibrium with the photons, so that at the Planck length all, real particles and antiparticles have the Planck energy as relativistic energy for their start in the correspondingly separated massive (Euclidian) universe and anti-universe. On this way, for these massless universes, we can derive a simple solution for the long-sought, four-dimensional quantum gravity, which via the transition from the final state of these massive universes to the big bang permits the determination of the parameters of the big bang and the evaluation of the lifetime of the sterile neutrinos, i.e. we obtain a cyclic evolution of the total (massless and massive) universes as a result of the dark energy converted half into (massless) photons or (massive) relics by the decay of the sterile neutrinos via the gravitation. We show that for the massive universe all results (except the age of its final state), derived in works [1-3], are confirmed. For the first time, we demonstrate that all these results [1-3] are also valid for the massive antiuniverse. For the massive universe, the critically analyzed, present-day, cosmological parameter values [5] are given in Table I. For better comparison of observed and estimated, present-day, cosmological parameter values, we mention here also their measured Planck 2013 data [10], summarized in Table II.Using these special properties of particles and antiparticles in Table III, we can also determine important quantities, which are necessary for the description of the massless and massive universe and anti-universe. These quantities are summarized in Table IV. However, the Friedmann-Lemaitre Equations and the new inflation model are only valid for scale factors R ;;:: Rp) . At R ~ Rp), for the massless universe and anti-universe, we must use the quantum cosmology or quantum gravity, for which the corresponding quantities are also given in Table IV. However, unfortunately, to this day, this quantum gravity is still highly incomplete and yields therefore no reliable predictions because the connection between cosmological "constant" and vacuum energy density is not clear [4]. Therefore, in this work, for the massless universes, by aid of the virtual matter of the quantum vacuum, we have derived a simple solution of the above-"mentioned four-dimensional quantum gravity.Under virtual matter, as a result of the uncertainty relation, we understand its formed particle-antiparticle (photon-photon) pairs, which have only an extremely short lifetime, so that they can be described however by a mean energy density and mean pressure. Because they are also formed in a radiation-free and matter-free space, the denotation "quantum vacuum" is usually applied. Taking the quantum field theory as a starting point, the total space-time continuum of the massless and the massive universe and antiuniverse is penetrated with this quantum vacuum, which forms a noneliminative background as ground state at absence of real matter. In this work, we have above assumed that from the big bang (88) at R = RBB , the immediately formed, massless universe and anti-universe expand in opposite direction, so that we obtain directly and correspondingly the separation of the virtual matter [photon(particle)-photon(anti-particle) pairs] of the massless universe and antimatter [photon(anti-particle)- photon(particle) pairs] of the massless anti-universe into real matter [photon(particle)-photon(particle) pairs] and antimatter [photon(antiparticle)- photon(antiparticle) pairs] as "two" real radiation fields as well as real particle (RBB ~ R ~ Rpl ) and antiparticle field (RBB ~ R ~ Rpl ) of the massless universe and anti-universe, respectively. 8ecause of the very high photon density of the massless universes, these processes are possible, whereat we must however consider that the photon is its own antiparticle. Therefore, in this work, for example, the thermal energy of the photons in the new thermal equilibrium is directly equivalent to the rest energy of the particles or antiparticles for the limiting case, where now the kinetic energy of the particles or antiparticles is zero, i.e. we can simply solve the separation of matter and antimatter. In the old interpretation, where here for the universe the particles and antiparticles are produced simultaneously by photons with the thermal energy of the sum of their rest energy in the thermal equilibrium, so that this old interpretation cannot solve the problem of the separation of matter and antimatter. Attention! In the next chapters. If for R ~ Rp1 we apply the FriedmannLemaitre Equations and the new inflation model for the description of universe and anti-universe" we mean always the massive universe and antiuniverse. This condition is also valid for the Tables I to IV. However, if for R ~ Rp1 we describe universe and anti-universe by the general vacuum energy density of the quantum gravity, we treat always the massless universe and anti-universe. This last condition is also valid for Tables I to IV. Therefore, this work is organized as follows. In Sec. 2, we describe shortly the Friedmann-lemaitre Equations as well as their most important, known solutions and problems, whereat we include SUSY GUTs. In Sec. 3, we derive a new inflationary cosmology, whereat we treat the neutrino data (sec. 3.1) the necessary properties of the X, Y gauge bosons (Sec. 3.2), the scale factors of absorption of light at the redshift condition before and after the inflation (Sec. 3.3), the necessary properties of the magnetic monopoles (Sec. 3.4), the definition of the new inflation model (Sec. 3.5) and the derivation of the vacuum energy density for universe and anti-universe by the new inflation model via quantities of the old inflation model at R = Rpl (Sec. 3.6). In Sec. 4, we find a simple solution for the four-dimensional quantum gravity via the vacuum energy density, whereat we treat the vacuum energy as a result of the negative pressure of the photons by a "new', quantum-statistical expression for their energy density at R = Rpl (Sec. 4.1), the vacuum energy density as a result of the negative pressure of the photons in thermal equilibrium with the particles or antiparticles via gravitation at R = Rp1 (Sec. 4.2), the particle formation or the general vacuum energy density as a result of the negative pressure of the photons in thermal equilibrium with the particles or antiparticles via the gravitation for R S Rpl (Sec. 4.3), the general vacuum energy density as a result of the negative pressure of the photons by a "new' quantum-statistical expression of their energy density for R ~ Rpl (Sec. 4.4) and some conclusions from the vacuum energy density or the cosmological "constant" (Sec. 4.5). In Sec. 5, we derive generally the curvature of the universe, whereat we show that this derivation must be valid also for the anti-universe. In Sec. 6, we define the most important, (present-day)
cosmological parameter values on the basis of general properties of particles and antiparticles for the description of universe and anti-universe by the Friedmann lemaitre Equations and the new inflation model. In Sec. 7, we describe shortly important, new results for the universe and the anti-universe as the final state and the end of the present, exponential expansion by a negative acceleration (Sec. 7.1), the astronomical unit changing (Sec. 7.2), the future by a slow, linear expansion after the present, accelerated expansion (Sec. 7.3) and the redshift values of the reionization (Sec. 7.4). In Sec. 8, we derive the heavy (anti)neutrino types. In Sec. 9, for the (anti-)universe, on the basis of observed sterile neutrino data, we introduce the sterile (anti)neutrino types for the dark (anti)matter (Sec. 9.1), the dark (anti-)energy (Sec. 9.2), the (anti)baryon mass (Sec. 9.3) and the photon decoupling [sterile eMS (anti)neutrinos] (Sec. 9.4) as well as explain semi-empirically the sterile (anti)neutrino calculations (Sec 9.5). In Sec. 10, we define special properties of all neutrino types for universe and anti-universe, whereat we treat the definition of the (present-day) cosmological parameter values by the rest energy of the heavy and the sterile (anti)neutrinos (Sec. 10.1) as well as the transformations of various types of the light and heavy as well as sterile (anti)neutrinos into one another (Sec. 10.2). In Sec. 11, we estimate the parameters of the big bang and evaluate the lifetime of the sterile neutrinos. In Sec. 12, we give a short summary. The values of the physical constants, used in this work, are given in works [5, 8].
