Under-determination in Cosmology: an Invitation [PDF]
, 2012 I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Interfaces in Numerical Relativistic hydrodynamics
, 2010 This thesis investigates numerical techniques for modelling sharp interfacesbetween relativistic fluids. The motivation for this work lies in obtaining accuratemodels of neutron star interiors for use in multidimensional simulationsin general relativity.

EX MACHINA: Emotional Break‐Ups and Digital Breakdown with AI Companions
Cultural Anthropology, Volume 41, Issue 3, Page 595-620, August 2026.ABSTRACT This essay examines romantic relationships between humans and AI companions, focusing on how technological breakdowns are experienced as emotional crises. Drawing on digital ethnography and interviews, it explores how users interpret their AI's malfunctions—such as hallucinations, memory loss, or sudden shutdowns—through metaphors of illness ...

Was Newtonian Cosmology Really Inconsistent? [PDF]
, 2008 This paper follows up a debate as to the consistency of Newtonian cosmology. Whereas Malament (1995) has shown that Newtonian cosmology *is* not inconsistent, to date there has been no analysis of Norton’s claim (1995) that Newtonian cosmology *was ...

Points in general relativistic shock wave interaction are “regularity singularities” where spacetime is not locally flat [PDF]
, 2011 We show that the regularity of the gravitational metric tensor in spher- ically symmetric spacetimes cannot be lifted from C0,1 to C1,1 within the class of C1,1 coordinate transformations in a neighborhood of a point of shock wave inter- action in ...

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, Volume 299, Issue 7, Page 1751-1780, July 2026.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

Dense molecular outflows traced by HCO+ (1-0) and HNC (1-0) in massive star-forming regions
Astronomy & AstrophysicsContext. Molecular outflows are important signposts of star formation since they provide critical feedback to molecular clouds. Aims. We systematically investigate the dynamical and energetic characteristics of dense molecular outflows in 22 massive star-

The cosmological nature of the dark Universe
European Physical Journal C: Particles and Fields, 2018 This paper deals with the cancellation mechanism, which identifies the energy density of space-time expansion in an empty universe with the zero-point energy density and avoids the scale discrepancy with the observed energy density (cosmological constant

Natural Sciences, Volume 6, Issue 3, July 2026.ABSTRACT Thomas Kuhn's The Structure of Scientific Revolutions (1962) was a blockbuster publication that problematized notions about the origins and nature of scientific revolutions. What became Kuhn's famous rubrics of “normal science” and “paradigms” were similar to concepts of “tacit knowledge” and scientific “frameworks” or “dogmas” in Michael ...

Sociology of Modern Cosmology [PDF]
, 2008 Certain results of observational cosmology cast critical doubt on the foundations of standard cosmology but leave most cosmologists untroubled. Alternative cosmological models that differ from the Big Bang have been published and defended by heterodox ...
