Quantum Gravity: A Primer for Philosophers. [PDF]
‘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 ...

Black hole thermodynamics: general relativity and beyond
Black holes have often provided profound insights into the nature of gravity and the structure of space–time. The study of the mathematical properties of black objects is a major research theme of contemporary theoretical physics.

THE THEORY OF RELATIVITY: ITS IMPACT ON MODERN PHYSICS
The Theory of Relativity, encompassing both Special and General Relativity, has profoundly reshaped the foundations of modern physics. This paper investigates the theoretical underpinnings and far-reaching consequences of Einstein’s revolutionary ideas ...

On Tensorial Concomitants and the Non-Existence of a Gravitational Stress-Energy Tensor [PDF]
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

What can we Learn about the Ontology of Space and Time from the Theory of Relativity [PDF]
This chapter presents an opinionated assessment of what we can learn about the ontology of space and time from the special and general theories of relativity.

Constraints on Gravitation from Causality and Quantum Consistency
We examine the role of consistency with causality and quantum mechanics in determining the properties of gravitation. We begin by examining two different classes of interacting theories of massless spin 2 particles—gravitons.

Generalization of Einstein’s gravitational field equations
The Riemann tensor is the cornerstone of general relativity, but as is well known it does not appear explicitly in Einstein’s equation of gravitation. This suggests that the latter may not be the most general equation. We propose here for the first time,

GUP parameter from quantum corrections to the Newtonian potential
We propose a technique to compute the deformation parameter of the generalized uncertainty principle by using the leading quantum corrections to the Newtonian potential.

Entropy Production and Equilibrium Conditions of General-Covariant Spin Systems
In generalizing the special-relativistic one-component version of Eckart’s continuum thermodynamics to general-relativistic space-times with Riemannian or post-Riemannian geometry as presented by Schouten (Schouten, J.A.

Physics for philosophers: Relativity Principle, Inertial Law and faith in what is impossible.
An attainable way to understand why we must reasonably doubt about a definite aspect of Albert Einstein´s geometric theory of gravitation, when he denies the character of force for gravity, is throughout the history of Relativity Principle and Inertial ...
