Projections of Earth's technosphere. I. Scenario modeling, worldbuilding, and overview of remotely detectable technosignatures
- 2024
Environmental Science
This study uses methods from futures studies to develop a set of ten self-consistent scenarios for Earth's 1000-year future, which can serve as examples for defining technosignature search…
Detectability of Solar Panels as a Technosignature
- 2024
Physics, Environmental Science
In this work, we assess the potential detectability of solar panels made of silicon on an Earth-like exoplanet as a potential technosignature. Silicon-based photovoltaic cells have high reflectance…
Technosignatures Longevity and Lindy's Law
- 2024
Physics
The probability of detecting technosignatures (i.e., evidence of technological activity beyond Earth) increases with their longevity, or the time interval over which they manifest. Therefore, the…
Deciding Technosignature Search Strategies: Multi-Criteria Fuzzy Logic to Find Extraterrestrial Intelligence
- 2024
Environmental Science
This study presents the implementation of Multi-Criteria Decision-Making (MCDM) methodologies, particularly the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS), in…
Detecting Technosignatures from Earth-scale Civilizations
- 2023
Engineering, Physics
Assuming civilizations have similar interplanetary communications and radar capability to NASA’s Deep Space Network, what is the feasibility of intercepting their communications? Interplanetary…
The oxygen bottleneck for technospheres
- 2023
Environmental Science, Physics
As oxygen is essential for respiration and metabolism for multicellular organisms on Earth, its presence may be crucial for the development of a complex biosphere on other planets. And because life…
The future of intelligence in the Universe: a call for humility
- 2023
Physics, Philosophy
Recent astrophysical findings suggest that the era during which the Universe is habitable has just begun. This raises the question whether the entire Universe may at some point in the future be…

Formación profesional y desafíos de empleabilidad en la industria aeroespacial: estado de la cuestión
- 2023
El interés de gobiernos y empresas privadas por invertir en el espacio ultraterrestre ha incrementado la importancia de la educación aeroespacial. El propósito del artículo consiste en examinar la…
A Bayesian Analysis of Technological Intelligence in Land and Oceans
- 2023
Environmental Science, Philosophy
Current research indicates that (sub)surface ocean worlds essentially devoid of subaerial landmasses (e.g., continents) are common in the Milky Way and that these worlds could host habitable…

Nitrogen Dioxide Pollution as a Signature of Extraterrestrial Technology
- 2021
Environmental Science, Physics
Nitrogen dioxide (NO2) on Earth today has biogenic and anthropogenic sources. During the Covid-19 pandemic, observations of global NO2 emissions have shown a significant decrease in urban areas.…

Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?
- 2018
Physics
‘Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar system. Recently, Micheli et al. reported that ‘Oumuamua showed deviations from a Keplerian orbit at a high…
A Drake Equation for Alien Artifacts.
- 2021
Philosophy
Scenarios are quantified that suggest that looking for alien artifacts near Earth is a credible alternative approach relative to listening to stars, and argues for emphasis on artifact searches, ET archeology.
Lunar Opportunities for SETI
- 2020
Physics, Engineering
Existing literature on Moon-based radio astronomy is reviewed, the benefits of lunar SETI are discussed, possible surface- and orbit-based telescope designs are contrasted, and it is argued that such initiatives are scientifically feasible within the next decade.
Contact inequality: first contact will likely be with an older civilization
- 2020
Economics
Abstract First contact with another civilization, or simply another intelligence of some kind, will likely be quite different depending on whether that intelligence is more or less advanced than…
Searching for Technosignatures through Network Analysis
- 2020
Physics, Computer Science
This is a network analysis approach to locate potential technosignatures in space and nodes represent exoplanet host stars (host stars as a proxy for ex planetet locations when working on exoplanets) through a network of nodes.
Dyson spheres
- 2020
Physics
I review the origins and development of the idea of Dyson spheres, their
purpose, their engineering, and their detectability. I explicate the ways in
which the popular imagining of them as…
