Pre-geometric Black Holes with Spherical Symmetry
Giuseppe Meluccio, Egor Pluzhnikov
Pre-geometric Gravity investigates the non-metric features of spacetime near the Planck scale, from which the gravitational interaction arises as a low-energy effective theory via…
Emergence of Gravity's Dynamical and Topological Sectors from Pre-geometry
Andrea Addazi, Giuseppe Meluccio
We identify the complete set of fundamental building blocks for a 4D pre-geometric theory of gravity. Based on a gauge theory of or coupled to a Higgs-like fiel…
The Pre-geometric Origin of Geometric Trinity of Gravity
Salvatore Capozziello, Giuseppe Meluccio
The so-called Geometric Trinity of Gravity is based on three distinct geometric features of spacetime, i.e.\ curvature, torsion and non-metricity, which give rise to equivalent dyn…
DESI and Dynamical Dark Energy from Extended Pre-geometric Gravity
Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +3
We consider the simplest quadratic extension of MacDowell--Mansouri pre-geometric gravity that preserves the topological pre-volume-form symmetry. Upon symmetry breaking, the theor…
olographic aturalness and Information See-Saw Mechanism for Neutrinos
Andrea Addazi, Giuseppe Meluccio
The microscopic origin of the de Sitter entropy remains a central puzzle in quantum gravity related to the cosmological constant problem. Within olographic $\mathcal{N…
olographic aturalness and Pre-Geometric Gravity
Andrea Addazi, Salvatore Capozziello, Giuseppe Meluccio
The cosmological constant (CC, ) problem represents a remarkable discrepancy of about 120 orders of magnitude between the observed dark energy and its natural expectation from q…
Non-local gravity effects in cosmological dynamics probed by IceCube/KM3NeT signals and dark matter relic abundance
Salvatore Capozziello, Gaetano Lambiase, Giuseppe Meluccio
Non-local gravity terms have a relevant role in determining the cosmological dynamics. Here we consider curvature- and torsion-based cosmological models where non-local terms can b…
Solution to the Cosmological Constant Problem from Pre-geometric Gravity
Andrea Addazi, Giuseppe Meluccio
We present a novel solution to the cosmological constant (CC) problem that requires no fine-tunings nor anthropic reasoning. In pre-geometric gravity (PGG), spacetime emerges from…
