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 ...

Minisuperspace Quantum Cosmology in Metric and Affine Theories of Gravity [PDF]
Universe, 2022 Minisuperspace Quantum Cosmology is an approach by which it is possible to infer initial conditions for dynamical systems which can suitably represent observable and non-observable universes. Here we discuss theories of gravity which, from various points

Switching Internal Times and a New Perspective on the `Wave Function of the Universe’
Universe, 2019 Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates, it is necessary to replace classical frames with ...

Combining general relativity and quantum theory: points of conflict and contact [PDF]
, 2001 The issues related to bringing together the principles of general relativity and quantum theory are discussed. After briefly summarising the points of conflict between the two formalisms I focus on four specific themes in which some contact has been ...

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

The Quantum Memory Matrix: A Unified Framework for the Black Hole Information Paradox [PDF]
EntropyWe present the Quantum Memory Matrix (QMM) hypothesis, which addresses the longstanding Black Hole Information Paradox rooted in the apparent conflict between Quantum Mechanics (QM) and General Relativity (GR).

One Hundred Years of General Relativity
, 2014 The aim of this two-volume title is to give a comprehensive review of one hundred years of development of general relativity and its scientific influences. This unique title provides a broad introduction and review to the fascinating and profound subject of general relativity, its historical development, its important theoretical consequences ...

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 ...

The fate of a quantum-corrected collapsing star in General Relativity [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 We incorporate some corrections inspired by loop quantum gravity into the concept of gravitational collapse and propose a complete model of the dynamic process.
