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 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 Numerical Testbed for Hypotheses of Extraterrestrial Life and Intelligence

, 2008
The search for extraterrestrial intelligence (SETI) has been heavily influenced by solutions to the Drake Equation, which returns an integer value for the number of communicating civilisations resident in the Milky Way, and by the Fermi Paradox, glibly ...

The Composite Conspiracy Belief (CCB) Scale: Development, Validation, and Distinction From Related Constructs

Applied Cognitive Psychology, Volume 39, Issue 6, November/December 2025.
ABSTRACT Conspiracy thinking is a multidimensional construct, studied both as a general disposition (conspiracy mindset) and as adherence to specific narratives (conspiracy beliefs). Despite research interest, distinguishing generic conspiracy thinking from related constructs (e.g., paranoid, magical thinking) remains a challenge.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, Volume 27, Issue 22, November 2025.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

The Impact of the Temporal Distribution of Communicating Civilizations on their Detectability

, 2017
We use a statistical model to investigate the detectability (defined by the requirement that they are in causal contact with us) of communicating civilizations within a volume of the universe surrounding our location.

Earth Detecting Earth: At What Distance Could Earth’s Constellation of Technosignatures Be Detected with Present-day Technology?

The Astronomical Journal
The field of Search for Extraterrestrial Intelligence (SETI) searches for “technosignatures” could provide the first detection of life beyond Earth through the technology that an extraterrestrial intelligence may have created.
