Anselm's Temporal‐Ontological Proof

Noûs, EarlyView.
ABSTRACT In his Reply to Gaunilo, Anselm presented two additional arguments for the existence of God beyond those that appear in the Proslogion. In “The Logical Structure of Anselm's Argument,” Robert M. Adams isolates each. One, he develops into a modal ontological argument along the lines of other 20th century ontological arguments (e.g., those of ...

Bekenstein’s Entropy Bound-Particle Horizon Approach to Avoid the Cosmological Singularity

Entropy, 2020
The cosmological singularity of infinite density, temperature, and spacetime curvature is the classical limit of Friedmann’s general relativity solutions extrapolated to the origin of the standard model of cosmology.

Probing time orientability of spacetime

European Physical Journal C: Particles and Fields, 2023
In general relativity, cosmology and quantum field theory, spacetime is assumed to be an orientable manifold endowed with a Lorentz metric that makes it spatially and temporally orientable.

Hybrid Deference, Hybrid Chance

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT If you learn about one kind of chance and nothing else, then you should defer to those chances. But what if you learn about more than one kind of chance? In such “hybrid” cases, familiar chance‐credence principles, like the Principal Principle, go silent when they should intuitively speak.

Jupiter's X‐ray Aurorae. A High Signal Spectral Analysis of the 0.24–1.40 keV Energy Range

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Jupiter's X‐ray auroras are predominantly produced by precipitating energetic heavy ions. Recent results suggest a connection between the pulsation rate of these ion aurorae and the pulsation rate of magnetospheric waves. Using remote X‐ray observations and results from in situ measurements from the Juno Jupiter Energetic particle Detector ...

Einstein, Planck and Vera Rubin: Relevant Encounters Between the Cosmological and the Quantum Worlds

Frontiers in Physics, 2021
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest the problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

A Wheeler–DeWitt Quantum Approach to the Branch-Cut Gravitation with Ordering Parameters

Universe, 2023
In this contribution to the Festschrift for Prof. Remo Ruffini, we investigate a formulation of quantum gravity using the Hořava–Lifshitz theory of gravity, which is General Relativity augmented by counter-terms to render the theory regularized.

The simplicity of physical laws

Noûs, Volume 59, Issue 4, Page 957-987, December 2025.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

A Non-Polynomial Gravity Formulation for Loop Quantum Cosmology Bounce

Galaxies, 2017
Recently the so-called mimetic gravity approach has been used to obtain corrections to the Friedmann equation of General Relativity similar to the ones present in loop quantum cosmology.
