Inflationary cosmology and the scale-invariant spectrum [PDF]
, 2017 The claim of inflationary cosmology to explain certain observable facts, which the Friedmann-Roberston-Walker models of `Big-Bang' cosmology were forced to assume, has already been the subject of significant philosophical analysis. However, the principal

A New Hilbert's Hotel Argument Against Past‐Eternalism
Analytic Philosophy, Volume 67, Issue 2, Page 145-153, June 2026.ABSTRACT This paper offers a new formulation of the “Hilbert's Hotel Argument” (HHA) which is superior to existing formulations because it (1) demonstrates that HH is logically impossible in the concrete world, (2) takes into account the need to consider the assumptions of HHA, and (3) offers a reply to an important objection concerning the validity of

Pulsar timing array observations as possible hints for nonsingular cosmology
European Physical Journal C: Particles and Fields, 2023 Recent pulsar timing array (PTA) experiments have reported strong evidence of the stochastic gravitational wave background (SGWB). If interpreted as primordial gravitational waves (GWs), the signal favors a strongly blue-tilted spectrum.

Alignment of the Starlings: Learning With Generative AI
Future Humanities, Volume 4, Issue 1, May 2026.ABSTRACT I will argue that answers to normative questions concerning the place of generative AI in learning rest on answers to ontological questions regarding (1) precisely what is happening when a human ‘interacts’ with generative AI and (2) What is distinctive about organic learning as opposed to currently existing ‘machine learning’ (3) What is the ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

High‐Latitude Zonal Jets in the Martian Upper Atmosphere Driven by Non‐Orographic Gravity Waves
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract We investigate thermosphere responses to non‐orographic gravity waves (GWs) using wind measurements from the Neutral Gas and Ion Mass Spectrometer onboard the Mars Atmosphere and Volatile EvolutioN mission, alongside simulations from the Mars Planetary Climate Model. We focus on zonal jets in high‐latitude regions of the upper atmosphere.

Looking beyond inflationary cosmology [PDF]
Canadian Journal of Physics, 2006 In spite of the phenomenological successes of the inflationary universe scenario, the current realizations of inflation making use of scalar fields lead to serious conceptual problems that are reviewed in this lecture. String theory may provide an avenue towards addressing these problems.

AMPERE Observations of the Asymmetry Toward Stronger Birkeland Currents in the Northern Hemisphere
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract We quantify the asymmetry between the Birkeland currents (also known as field‐aligned currents) in the Northern and Southern Hemispheres. We use data from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) in 2010–2024 inclusive for both hemispheres, compute the observed asymmetry, and then subtract the modeled

A Possible Solution to the Mystery of the ANITA Anomalous Events
Annalen der Physik, Volume 538, Issue 4, April 2026.In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.
