Does DESI Provide Evidence for Dynamical Dark Energy?
Nicola Bamonti
Recent results from the Dark Energy Spectroscopic Instrument (DESI) have suggested that dark energy, long considered to be a cosmological constant, may actually be \lq{}dynamical\r…
Apples Falling, Buckets Rolling, and Why Inertia Keeps Trolling: Inertial Motion is Not Natural Motion
Nicola Bamonti
Inertia has long been treated as the paradigm of natural motion. This paper challenges this identification through the lens of General Relativity. Drawing on Norton (2012)'s distin…
The Hole Argument for Reference Frames
Nicola Bamonti, Henrique Gomes
We exploit the results of Bamonti and Gomes (2024) concerning the dynamical (un)coupling of reference frames to gravity to analyse the role of reference frames in the Hole Argument…
Relational Observables and Physical Perspectivalism in General Relativity: The View from Nowhere vs. The View from Everywhere
Nicola Bamonti
In General Relativity, relational constructions yield gauge-invariant Dirac observables by expressing physical fields relative to reference frames. This leaves open how the physica…
In Search of Cosmic Time: Complete Observables and the Clock Hypothesis
Nicola Bamonti, Karim P. Y. Thébault
This paper considers a new and deeply challenging face of the problem of time in the context of cosmology drawing on the work of Thiemann (2006, 2007). Thiemann argues for a radica…
Rethinking Symmetry Principles and Partial Observables With Reference Frames
Nicola Bamonti, Henrique Gomes
Dynamically uncoupled fields are a modelling device used in the literature on reference frames, classical and quantum. We argue that the device is not innocuous. First, uncoupled f…
What is a reference frame in General Relativity?
Nicola Bamonti
This work introduces a novel three-fold classification of reference frames in General Relativity, distinguishing between Idealised Reference Frames (IRFs), Dynamical Reference Fram…
Features of the Primordial Universe in f(R)-gravity as viewed in the Jordan frame
Nicola Bamonti, Andrea Costantini, Giovanni Montani
We analyze some relevant features of the primordial Universe as viewed in the Jordan frame formulation of the f(R)-gravity, especially when the potential term of the non-minimally…
