The ΛCDM-NG Cosmological Model: A Possible Resolution of the Hubble Tension
The Astrophysical JournalWe offer a cosmological model based on conventional general relativity (no speculative physics) that may resolve the Hubble tension. A reanalysis of the foundation of the Lambda-CDM model shows that general relativity alone does not specify what fraction

Quantum Gravity: A Primer for Philosophers. [PDF]
, 2008 ‘Quantum Gravity’ does not denote any existing theory: the field of quantum gravity is very much a ‘work in progress’. As you will see in this chapter, there are multiple lines of attack each with the same core goal: to find a theory that unifies, in ...

On Tensorial Concomitants and the Non-Existence of a Gravitational Stress-Energy Tensor [PDF]
, 2009 Based on an analysis of what it may mean for one tensor to depend in the proper way on another, I prove that, under certain natural conditions, there can be no tensor whose interpretation could be that it represents gravitational stress-energy in general
