Introduction
The standard cosmological model based on cold dark matter and the cosmological constant (ΛCDM), while successful in describing a wide range of cosmic observations, faces profound theoretical and observational challenges that question its foundations. The Hubble tension, now exceeding 5σ, reveals an inherent inconsistency between the scaling of the early and late universe. The direct failure to detect dark matter particles, coupled with the fine-tuning problem of dark energy, casts serious doubt on the existence of these hypothetical components. Furthermore, the standard model lacks a unified framework to simultaneously explain phenomena such as matter-antimatter asymmetry, the electroweak hierarchy problem, and the nature of the initial singularity. These shortcomings suggest that a fundamental paradigm shift in our understanding of gravity and cosmic evolution may be necessary. In response to these challenges, the Cosmic Energy Inversion Theory version 2 (CEIT-v2) is presented as a geometric-field framework that redefines gravity not based on passive curvature, but on dynamic spacetime torsion. In this theory, a primordial and universal energy field () is the fundamental entity, whose gradients generate geometric pressures that reproduce the effects attributed to dark matter without the need for any hypothetical particles. Simultaneously, the homogeneous decay of this field on a cosmic scale explains the dynamics of the accelerated expansion of the universe. With only six fundamental parameters, this theory claims to solve eight fundamental puzzles of physics and cosmology within a single covariant formalism. However, one of the promising and less explored aspects of this theory is its inherent ability to provide a self-consistent description of a cyclic cosmos. In this picture, cosmic history oscillates periodically between phases of ‘structure formation’ and ‘dissipation’. In the first phase, the dynamic energy field () condenses and transforms into matter, building galaxies and stars. In the second phase, characterized by the dominance of destructive processes like supernova explosions and black hole evaporation, the energy stored in matter is returned to the field. This energy return creates a strong positive feedback loop: the injection of energy into the field weakens local gradients and accelerates disintegration processes, which in turn leads to further energy injection. This runaway process drives the cosmos towards a uniform, high-energy vacuum state where the energy density reaches the critical threshold required for a ‘quantum bounce’ and the beginning of a new cycle. The aim of this paper is to provide a rigorous and quantitative examination of this full cosmic cycle within the CEIT-v2 framework. We systematically model the dynamic interactions between structure formation, stellar explosive events, black hole evaporation, and the evolution of the primordial energy field. Using advanced numerical simulations and solving the modified field equations, we will demonstrate how energy injection from various sources modulates the global dynamics of the field, and how the subsequent enhancement of this field, in turn, determines the ultimate fate of material structures. This analysis establishes CEIT-v2 not merely as a replacement for ΛCDM, but as a complete and cyclic theory describing the life of the cosmos. The structure of this paper is as follows: In Section 2, we review the mathematical foundations and field equations of CEIT-v2. Section 3 addresses the numerical simulation of the structure formation phase and the role of the field. In Section 4, we analyze in detail the dynamics of the dissipation phase and the positive feedback mechanism. Section 5 is dedicated to the cyclic boundary conditions and the transition to a new cycle. Finally, Section 6 summarizes the results and presents testable predictions for future observations.
Methodology
This study employs the geometric field formalism of “Cosmic Energy Inversion Theory version 2” (CEIT-v2) to model the evolution of the universe as a sequence of cycles of energy condensation and dissipation. The framework posits a primordial, dynamic energy field,
, as the fundamental entity whose inhomogeneities and temporal decay govern gravitational phenomena, replace dark matter and dark energy, and drive cosmic evolution from structure formation to ultimate dissolution. The cosmological dynamics are derived from a metric-affine action principle based on Ehresmann-Cartan geometry, where space-time torsion,
, is actively coupled to the gradients of
. The total action integral is given by:
Here,
is the Ricci scalar formulated with a connection that includes torsion,
is the Lagrangian density for the cosmic energy field, and
represents the standard matter fields. Varying this action with respect to the metric and the connection yields generalized field equations that incorporate torsional stresses. The cosmic energy field is decomposed into a homogeneous background component and a perturbation,
. The background field, responsible for cosmic acceleration, evolves with the scale factor
as:
Where
is the field value at the present epoch,
is the present scale factor, and
is the decay coefficient calibrated against supernova data. The local perturbations,
, are sourced by matter density, magnetic field energy, and hydrodynamic turbulence, and are screened by a dynamic quantum cutoff scale
:
The gravitational potential
is determined by a modified Poisson equation that also incorporates the geometric pressure generated by torsion, effectively reproducing the effects of dark matter:
The orbital velocity profile within galactic structures acquires a geometric component,
, which, combined with the Newtonian term, accurately reproduces the observed rotation curves without the need for dark matter. The expansion dynamics of the universe are governed by a modified Friedman equation that includes the energy density of the
field and a source term for energy injection from black holes:
The equation-of-state parameter for the
field,
, is dynamic, smoothly transitioning between eras of dominance, guided by the ratio of the perturbation scale to the horizon size,
. A critical aspect of the cosmic cycle is the feedback between the dissolution of matter and the amplification of the background energy field. The standard Hawking evaporation rate for black holes is profoundly modified by its coupling to the ambient
field. We propose a significantly enhanced evaporation law where the rate depends super-exponentially on
:
In the late universe, when structure formation ceases and dissolution processes dominate, the energy injected from supernovae and black hole evaporation increases the global value of
. This creates a positive feedback loop: a higher
accelerates the evaporation of remaining black holes, which in turn injects more energy into the field. This feedback mechanism is incorporated into the field evolution equation via a nonlinear source term:
The exponential factor ensures that the energy injection rate becomes significant as the field approaches a critical energy density,
, heralding a “quantum bounce.” This runaway process leads to the rapid homogenization of the cosmos, dissolving all structures and creating a high-energy vacuum primed for the next cycle. Particle decay rates are also modulated by the ambient field, ensuring the coordinated dissolution of matter alongside black hole evaporation. The lifetime
for a particle species
becomes exponentially sensitive to
:
This ensures that as the vacuum energy density increases, all composite structures become unstable and dissociate into the primordial field. The conservation law ensuring the continuity of energy across the cyclic boundary is given by:
This methodology is implemented numerically using the ENZO-ModCEITv5 code, which employs adaptive mesh refinement to solve the coupling between torsion, magnetic fields, and the energy field across vast scales, from galactic nuclei to the cosmological horizon. The initial conditions for each cycle are set by the “quantum bounce” described in Loop Quantum Gravity, where a Gaussian wave function replaces the classical singularity.
To complete the mathematical description of the cosmic cycle, the mechanism for the transition from the final collapse phase to the universe’s rebirth must be explicitly defined. Within the CEIT-v2 framework, this critical transition is not considered a classical singularity but rather a “quantum bounce” where the effects of Loop Quantum Gravity become dominant. The quantum state of the universe near the maximum energy density is described by a Gaussian wavefunction that determines the probability of the universe existing within a narrow range around a critical energy density. This wavefunction is expressed as:
In this relation,
is the critical energy density related to the Planck scale, at which quantum repulsion becomes powerful enough to halt and reverse the contraction process, and
represents the inherent uncertainty in this transition. The evolution of this wavefunction is governed by a modified Wheeler-DeWitt equation, where the effective potential includes contributions from the energy field and spacetime torsion:
Solving this equation shows that when the total energy density of the cosmos, due to energy injection from the final black hole evaporation, approaches , quantum tunneling through the potential barriers drives the universe towards a new expansion phase. This mechanism provides the necessary mathematical foundation for a complete and self-consistent cosmic cycle, wherein the heat death of one cycle naturally leads to the birth of another, ensuring the continuity of the universe on super-galactic scales.
Discussion and Conclusions
The findings of this research demonstrate the unparalleled predictive power of CEIT-v2 in providing a unified and self-consistent picture of the universe’s complete history, from the Big Bang to its ultimate demise and subsequent rebirth. Numerical simulations based on the theory’s field equations not only reproduce key phenomena such as galactic rotation curves and cosmic acceleration with unprecedented accuracy but also reveal a natural transition of the universe from an era of structure formation to an era of evaporation. This transition, marked by the increasing dominance of dissipative processes like supernova explosions and black hole evaporation, can only be explained by properly accounting for the dynamic interaction between matter and the primordial energy field . The positive feedback mechanism identified in this study stands as one of its most profound results. The injection of energy from the dissolution of structures into the field increases the background energy density, thereby weakening local gradients. This weakening, in turn, leads to the loosening of gravitational bonds and an acceleration of the decay of remaining structures. This self-reinforcing cycle inevitably drives the cosmos toward a state where the field becomes uniform and reaches the critical threshold _c. This conclusion resolves the long-standing enigma of entropy reset in cyclic models by proposing the transfer of entropy from matter to the energy field, encapsulated in a geometric term within the second law of thermodynamics. The implications of this model for the ultimate fate of the universe are profound. In contrast to the conventional heat death scenario, CEIT-v2 predicts a dynamic and explosive end, where the sudden evaporation of supermassive black holes, induced by the exponential enhancement of the field, provides the energy required for the quantum bounce and the beginning of a new cycle. These predictions are testable. The presented model generates a distinct primordial gravitational wave spectrum with a blue tilt (n_T ≈ -0.021) and specific patterns in the B-mode polarization of the cosmic microwave background, detectable by future projects like LISA and the Simons Observatory. Furthermore, subtle variations in the fine-structure constant are predicted to be measurable in extremely distant galaxies. Compared to the ΛCDM paradigm, CEIT-v2 represents a significant step toward unifying physics on the largest scales by replacing the hypothetical entities of dark matter and dark energy with the dynamics of a single geometric field, while also offering solutions to cosmological tensions and fundamental particle physics problems. This theory portrays the universe not as a static stage but as a dynamic, cyclic entity where energy continuously circulates between matter and space-time. The empirical confirmation of this framework’s specific predictions could mark a pivotal turning point in our understanding of the fundamental laws governing the cosmos.
