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 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.

The Herschel Virgo Cluster Survey. VII. Dust in cluster dwarf elliptical galaxies [PDF]
, 2010 We use the science demonstration phase data of the Herschel Virgo Cluster Survey to search for dust emission of early-type dwarf galaxies in the central regions of the Virgo cluster as an alternative way of identifying the interstellar medium. We present

Properties of interstellar dust [PDF]
Journal of Geophysical Research: Space Physics, 2000 The reference abundance of the interstellar medium (the abundance of elements in gas + dust), until recently assumed to be solar, is discussed because of its great importance for the composition of dust. For some important elements (O, N, and probably more), three lines of reasoning (observed gas‐phase abundances, H II regions, and stellar abundances ...

The Flattest Infrared Extinction Curve in Four Isolated Dense Molecular Cloud Cores
The Astrophysical Journal LettersThe extinction curve of interstellar dust in the dense molecular cloud cores is crucial for understanding dust properties, particularly size distribution and composition.

Statistical properties of dust far-infrared emission
, 2007 The description of the statistical properties of dust emission gives important constraints on the physics of the interstellar medium but it is also a useful way to estimate the contamination of diffuse interstellar emission in the cases where it is ...

Properties of Interstellar Dust [PDF]
International Astronomical Union Colloquium, 1996 AbstractIn this review, the picture of the interstellar dust is outlined from the viewpoint of its role in galactic evolution. The modern concept of distinct dust populations is presented. The properties of the dust grains in the diffuse interstellar medium and in the molecular clouds are described.

Estimating dust distances to Type Ia supernovae from colour excess time-evolution
, 2017 We present a new technique to infer dust locations towards reddened Type Ia supernovae and to help discriminate between an interstellar and a circumstellar origin for the observed extinction. Using Monte Carlo simulations, we show that the time-evolution

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2
The Astrophysical JournalDiffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

A Model Connecting Galaxy Masses, Star Formation Rates, and Dust Temperatures Across Cosmic Time
, 2018 We investigate the evolution of dust content in galaxies from redshifts z=0 to z=9.5. Using empirically motivated prescriptions, we model galactic-scale properties -- including halo mass, stellar mass, star formation rate, gas mass, and metallicity -- to

Dust production scenarios in galaxies at z ~ 6-8.3
, 2019 The mechanism of dust formation in galaxies at high redshift is still unknown. Asymptotic giant branch (AGB) stars and explosions of supernovae (SNe) are possible dust producers, and non-stellar processes may substantially contribute to dust production ...
