Running of the cosmological constant and estimate of its value in quantum general relativity [PDF]
Modern Physics Letters A, 2015 We present the connection between the running of the cosmological constant and the estimate of its value in the resummed quantum gravity (RQG) realization of quantum general relativity. We also address in this way some of the questions that have been raised concerning this latter generalization and application of the original prescription of Feynman ...

Quantum Cosmology: Cosmology directly linked to the Planck Scale in General Relativity Theory and Newton Gravity [PDF]
, 2023 We will in this paper demonstrate that there is a link between cosmology and the Planck scale. It has in recent years been shown that the Planck length can be found totally independent on \(G\), \(\hbar\) and \(c\) and that a series of cosmological predictions can be predicted only from two constants, namely the Planck length and the speed of gravity ...

A new cosmology of a crystallization process (decoherence) from the surrounding quantum soup provides heuristics to unify general relativity and quantum physics by solid state physics [PDF]
, 2021 We explore a cosmology where the Big Bang singularity is replaced by a condensation event of interacting strings. We study the transition from an uncontrolled, chaotic soup (“before”) to a clearly interacting “real world”. Cosmological inflation scenarios do not fit current observations and are avoided.

Abstract Quantum Vibrational Relativity (QVR) proposes that spacetime itself is a vibrational field whose layered modes generate all known physical phenomena.In this framework, dark matter and dark energy emerge as complementary binding and expansive modes of the same scalar field, while observable reality arises from systems tuning to specific ...

This preprint proposes a temporal‑lattice framework for quantum gravity and unification. The central hypothesis is that spacetime at the most fundamental scale is a causal lattice with discrete time steps and spatial sites, and that all physical degrees of freedom—geometry, gauge fields, and matter—are realized as temporal‑phase patterns on this ...

European Physical Journal C: Particles and FieldsThe Moore–Penrose algorithm provides a generalized notion of an inverse, applicable to degenerate matrices. In this paper, we introduce a covariant extension of the Moore–Penrose method that permits to deal with general relativity involving complex non ...

Exactly solvable quantum cosmologies from two killing field reductions of general relativity
Nuclear Physics B, 1989 Abstract An exact and, possibly, general solution to the quantum constraints is given for the sector of general relativity containing cosmological solutions with two space-like, commuting, Killing fields. The dynamics of these model space-times, which are known as Gowdy space-times, is formulated in terms of Ashtekar's new variables. The quantization
