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).

Hybrid Loop Quantum Cosmology: An Overview
Frontiers in Astronomy and Space Sciences, 2021 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
Universe, 2022 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
Physical Sciences Forum, 2023 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 ...

A scientometric study of general relativity and quantum cosmology from 2000 to 2012 [PDF]
Scientometrics, 2015 2015 is the centennial of Einstein General Relativity. On this occasion, we examine the General Relativity and Quantum Cosmology (GRQC) field of research by analysing 38291 papers uploaded on the electronic archives arXiv.org from 2000 to 2012. We establish a map of the countries contributing to GRQC in 2012.

L'emergenza dello spazio-tempo nella gravità quantistica e nella cosmologia quantistica
Philosophy Kitchen, 2019 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.

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 ...

Does a Theory of Everything Exist?
Философия и космология, 2021 Since Einstein’s failure to define a Grand Unified Theory, physicists have pursued a comprehensive theory explaining nature, a Theory of Everything. But because General Relativity, Quantum Field Theory, and Cosmology have little in common, defining one ...
