Cosmological Special Theory of Relativity, Cosmological Quantum Physics, Cosmological Uncertainty Principles, Cosmological General Theory of Relativity [PDF]
In cosmological special relativity theory, we study Maxwell equations, electromagnetic wave equations and functions. In the cosmological special theory of relativity, we study energy?momentum relations, the Klein-Gordon equation and wave functions. If we solve the Klein?Gordon equation, we obtain the Yukawa potential in the cosmological inertial frame.

Switching Internal Times and a New Perspective on the `Wave Function of the Universe’
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 ...

The Quantum Memory Matrix: A Unified Framework for the Black Hole Information Paradox [PDF]
We 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).

Hybrid Loop Quantum Cosmology: An Overview
Loop Quantum Gravity is a nonperturbative and background independent program for the quantization of General Relativity. Its underlying formalism has been applied successfully to the study of cosmological spacetimes, both to test the principles and ...

Gauge-Invariant Perturbations at a Quantum Gravity Bounce
We study the dynamics of gauge-invariant scalar perturbations in cosmological scenarios with a modified Friedmann equation, such as quantum gravity bouncing cosmologies.

A Rotating Model of a Light Speed Expanding Hubble-Hawking Universe
Based on light speed expansion, a modified red shift formula, a scaled Hawking’s black hole temperature formula, the super gravity of galactic baryon matter and baby Planck ball, in our recent publications we have clearly established a novel model of ...

L'emergenza dello spazio-tempo nella gravità quantistica e nella cosmologia quantistica
Our best description of spacetime is provided by general relativity – yet, this theory is not thought to be fundamental. Instead, it is expected to be replaced by a theory of quantum gravity, which may not feature spacetime fundamentally.

A Brief Introduction to Loop Quantum Cosmology [PDF]
In recent years, Loop Quantum Gravity has emerged as a solid candidate for a nonperturbative quantum theory of General Relativity. It is a background independent theory based on a description of the gravitational field in terms of holonomies and fluxes ...

Black Hole Thermodynamics [PDF]
The discovery in the early 1970s that black holes radiate as black bodies has radically affected our understanding of general relativity, and offered us some early hints about the nature of quantum gravity.
