Dark Energy Problem, Physics of Early Universe and Some New Approaches in Gravity
Entropy, 2012
The dark energy problem is studied based on the approach associated with the cosmological term in General Relativity that is considered as a dynamic quantity. It is shown that a quantum field theory of the Early Universe (Planck scales) and its limiting transition at low energy play a significant role. Connection of this problem with Verlinde's new (entropic) approach to gravity is revealed within the frame of such statement as well as the Generalized Uncertainty Principle (GUP) and Extended Uncertainty Principle (EUP). The implications from the obtained results are presented, and a more rigorous statement of the Concordance Problem in cosmology is treated.
Cosmological dark energy: prospects for a dynamical theory
New Journal of Physics, 2007
We present an approach to the problem of vacuum energy in cosmology, based on dynamical screening of on the horizon scale. We review first the physical basis of vacuum energy as a phenomenon connected with macroscopic boundary conditions, and the origin of the idea of its screening by particle creation and vacuum polarization effects. We next discuss the relevance of the quantum trace anomaly to this issue. The trace anomaly implies additional terms in the low-energy effective theory of gravity, which amounts to a non-trivial modification of the classical Einstein theory, fully consistent with the Equivalence Principle. We show that the new dynamical degrees of freedom the anomaly contains provide a natural mechanism for relaxing to zero on cosmological scales. We consider possible signatures of the restoration of conformal invariance predicted by the fluctuations of these new scalar degrees of freedom on the spectrum and statistics of the cosmic microwave background radiation (CMB), in light of the latest bounds from WMAP. Finally we assess the prospects for a new cosmological model in which the dark energy adjusts itself dynamically to the cosmological horizon boundary, and therefore remains naturally of order H 2 at all times without fine tuning.
On the Nature of Dark Energy, Cosmological Constant and Dark Matter
viXra, 2018
In the present essay, we consider the origin of the dark energy, cosmological constant and the dark matter. The dark energy, is consequence of the annihilation of the matter-antimatter at the very biginning of the big bang.This dark energy was the origin and cause of the cosmological expansion and the past and present creation of the whole space. We consider the presence of the call "dark" matter as consequence of highly exited hydrogen and helium Ridberg's atoms in perfect equilibrium with the CMB radiation. The cosmological constant is considered as an arbitrary ad hoc anti gravitational entity. Finally, we consider the Casimir effect, as a suitable and truly efficient physical method and a reliable resource in the experimental determination of the dark energy.
Remarks on the Formulation of the Cosmological Constant/Dark Energy Problems
Foundations of Physics, 2007
Associated with the cosmic acceleration are the old and new cosmological constant problems, recently put into the more general context of the dark energy problem. In broad terms, the old problem is related to an unexpected order of magnitude of this component while the new problem is related to this magnitude being of the same order of the matter energy density during the present epoch of cosmic evolution. Current plans to measure the equation of state or density parameters certainly constitute an important approach; however, as we discuss, this approach is faced with serious feasibility challenges and is limited in the type of conclusive answers it could provide. Therefore, is it really too early to seek actively for new tests and approaches to these problems? In view of the difficulty of this endeavor, we argue in this work that a good place to start is by questioning some of the assumptions underlying the formulation of these problems and finding new ways to put this questioning to the test. First, we calculate how much fine tuning the cosmic coincidence problem represents. Next, we discuss the potential of some cosmological probes such as weak gravitational lensing to identify novel tests to probe dark energy questions and assumptions and provide an example of consistency tests. Then, motivated by some theorems in General Relativity, we discuss if the full identification of the cosmological constant with vacuum energy is unquestionable. We discuss some implications of the simplest solution for the principles of General Relativity. Also, we point out the relevance of experiments at the interface of astrophysics and quantum field theory, such as the Casimir effect in gravitational and cosmological contexts. We conclude that challenging some of the assumptions underlying the cosmological constant problems and putting them to the test may prove useful and necessary to make progress on these questions.
The solution of the dark energy problem
2021
The condensation mechanism of primary fermions with the Planck mass in the cosmological model with superconductivity (CMS) makes it possible to describe the process of dark energy formation. Its calculated density is equal to 6•10-30 g/cm 3 and coincides well with data of PLANK collaboration and others. In CMS the evolution of the Universe is described as an ongoing process of condensation of primary fermions. Black holes can also be thought of as a gravitational condensate of primary fermions.

The dark energy, is consequence of the annihilation of the matter antimatter at the very biginning of the big bang.This dark energy was the origin and cause of the cosmological expansion and the past and present creation of the whole space. We take into account the presence of the call “dark” matter as consequence of highly excited hydrogen and helium Ridberg’s atoms in perfect equilibrium with the CMB radiation. The cosmological constant is considered as an arbitrary ad hoc anti gravitational entity. Finally, we note that the Casimir effect, as a suitable and truly efficient physical method and a reliable resource in the experimental determination of the dark energy.

Gravitation and Cosmology
Based on quantum mechanics and general relativity, Karolyhazy proposed a generalization to the well-known Heisenberg uncertainty relation in which the energy density of quantum fluctuations of space-time plays a crucial role. Later on, various holographic DE models were suggested, in which the Hubble scale (size) and the age of the universe were assumed as measures for the largest infrared cutoff satisfying the holographic principle and energy bounds assuring applicability of quantum field theory. We review various models based on the holographic principle and the Karolyhazy relation and compare these to the space-time foam and superconducting DE models. We analyze their (in)stability against cosmological perturbation.
