Beyond the Metric: Geometrical Measurability as a Constraint on Quantum Gravity
Matteo Tuveri
This paper develops an epistemological constraint on quantum gravity grounded in the empirical meaning of general relativity. The central claim is that a complete recovery of gener…
Long-Range Quantum Gravity
M. Cadoni, M. Tuveri, A. P. Sanna
It is a tantalising possibility that quantum gravity (QG) states remaining coherent at astrophysical, galactic and cosmological scales could exist and that they could play a crucia…
Anisotropic Fluid Cosmology: an Alternative to Dark Matter?
Mariano Cadoni, Andrea P. Sanna, Matteo Tuveri
We use anisotropic fluid cosmology to describe the present, dark energy-dominated, universe. Similarly to what has been proposed for galactic dynamics, the anisotropic fluid gives…
Galactic dynamics and long-range quantum gravity
Matteo Tuveri, Mariano Cadoni
We explore in a systematic way the possibility that long-range quantum gravity effects could play a role at galactic scales and could be responsible for the phenomenology commonly…
A new perspective on galactic dynamics
Matteo Tuveri, Mariano Cadoni
We derive the radial acceleration of stars in galaxies by using basic features of thermodynamics, statistical mechanics and general relativity. We assume that the "dark" component…
Sine-Gordon solitonic scalar stars and black holes
Edgardo Franzin, Mariano Cadoni, Matteo Tuveri
We study exact, analytic, static, spherically symmetric, four-dimensional solutions of minimally coupled Einstein-scalar gravity, sourced by a scalar field whose profile has the fo…
Emergence of a Dark Force in Corpuscular Gravity
Mariano Cadoni, Roberto Casadio, Andrea Giusti +1
We investigate the emergent laws of gravity when Dark Energy and the de Sitter space-time are modelled as a critical Bose-Einstein condensate of a large number of soft gravitons $N…
Effective Fluid Description of the Dark Universe
Mariano Cadoni, Roberto Casadio, Andrea Giusti +2
We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly at…
Emergent Gravity from an Augmented Variational Principle
Matteo Tuveri, Lorenzo Fatibene, Marco Ferraris
A direct and non-trivial link between Padmanabhan's entropy used in emergent gravity and standard GR action is established. To do that, Augmented Variational Principles (AVP) will…
