Simulations All the Way Up! An Atheist's Response to the Fine‐Tuning Argument

Analytic Philosophy, EarlyView.
ABSTRACT So the Fine‐tuning Argument goes, because it is so unlikely for the physical constants of the laws of nature to have taken the values that they in fact take, we should significantly raise our credence that God exists. Simulation Arguments argue that our world might be (or, in stronger versions, that it probably is) a mere computer simulation ...

Generalized Te([O iii])–Te(He i) Discrepancies in Ionized Nebulae: Possible Evidence of Case B Deviations and Temperature Inhomogeneities

The Astrophysical Journal
The physics of recombination lines in the He i singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the intensities of He i singlets λ 3614,  λ 3965,  λ 5016,  λ 6678, and  λ 7281 and the triplet He i λ 5876

On Our Cosmic (In)significance

Ratio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, Volume 58, Issue 12, Page 1136-1145, December 2026.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Seed Storage Conditions for Zostera muelleri Restoration: Effects of Temperature, Salinity and Sterilisation on Seed Contamination, Viability and Seedling Emergence

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
The decline of seagrass meadows is a continuing global concern, and seed‐based restoration provides a scalable approach to recovering lost and degraded meadows. Such approaches require large quantities of seed to be collected, processed, and often stored for months until deployment.

Iron abundances and heating of the intracluster medium in hydrodynamical simulations of galaxy clusters

, 2003
Hydrodynamical SPH simulations of galaxy clusters are used to investigate the metal enrichment of the intracluster medium. The final metallicity abundances of the simulated clusters are determined according to the numerical resolution and a number of ...
