Abstract We address the possibility that intelligent civilizations that destroy themselves could present signatures observable by humanity. Placing limits on the number of self-destroyed civilizations in the Milky Way has strong implications for the final three terms in Drake's Equation, and would allow us to identify which classes of solution to Fermi's Paradox fit with the evidence (or lack thereof). Using the Earth as an example, we consider a variety of scenarios in which humans could… Expand
A Statistical Approach to Illustrate the Challenge of Astrobiology for Public Outreach
It is shown that the probability of the existence of evolved extraterrestrial forms of life increases with distance from the Earth while, at the same time, the number of detectable biosignatures decreases due to technical and physical limitations. Expand
SET-E: The Search for Extraterrestrial Environmentalism
There is currently no evidence for life on any known exoplanet. Here, we propose a form of "galactic anthropology" to detect not only the existence of life on transiting exoplanets, but also theExpand

Abstract The Zoo solution to Fermi's Paradox proposes that extraterrestrial intelligences (ETIs) have agreed to not contact the Earth. The strength of this solution depends on the ability for ETIs toExpand
Searching for Technosignatures: Implications of Detection and Non-Detection
The search for technosignatures from the Galaxy or the nearby universe raises two main questions: What are the possible characteristics of technosignatures? and How can future searches be optimizedExpand
Exoplanetary Biosignatures for Astrobiology
Since life evolved on our planet there have been subtle interplays between biology and Earth System Components (atmosphere-lithosphere-ocean-interior). Life, for example, can impact weathering ratesExpand
A New Empirical Constraint on the Prevalence of Technological Species in the Universe.
It is found that as long as the probability that a habitable zone planet develops a technological species is larger than ∼10(-24), humanity is not the only time technological intelligence has evolved. Expand
On the Broader Sense of Life and Evolution: Its Mechanisms, Origin and Probability across the Universe
We consider connection between the mechanisms of evolution of life and the existence of conditions suitable for life in the universe. In particular we review the problem of calculating the number ofExpand
The Log Log Prior for the Frequency of Extraterrestrial Intelligences
It is unclear how frequently life and intelligence arise on planets. I consider a Bayesian prior for the probability P(ETI) that intelligence evolves at a suitable site, with weight distributedExpand
Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets.
A new method to probe atmospheric pressure on Earth-like planets using (O2-O2) dimers in the near-infrared is presented and it is shown that in some cases it may be possible to estimate the pressure at the reflecting surface of a planet. Expand
Relative Likelihood of Success in the Search for Primitive versus Intelligent Extraterrestrial Life.
It is suggested that the search for extraterrestrial intelligence (SETI) may merit a federal funding level of at least $10 million per year, assuming that the average lifetime of technological species exceeds a millennium. Expand


Spatio-temporal constraints on the zoo hypothesis, and the breakdown of total hegemony

Abstract The Zoo Hypothesis posits that we have not detected extraterrestrial intelligences (ETIs) because they deliberately prevent us from detecting them. While a valid solution to Fermi's Paradox,Expand
It is found that the maximum Galaxy colonization timescale is actually much shorter than previous work has found, and that many "sustainability" counter-arguments to Hart's thesis suffer from the monocultural fallacy. Expand
Nuclear waste spectrum as evidence of technological extraterrestrial civilizations
Abstract We consider the possible observational consequences of galactic civilizations which utilize their local star as a repository for radioactive fissile waste material. If a relatively smallExpand
If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?: Fifty Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life
Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-oldExpand

The true function of the recent past of exoplanet atmospheric research has been not to constrain planet properties for all time, but to train a new generation of scientists who, by rapid trial and error, are fast establishing a solid future foundation for a robust science ofExoplanets. Expand
Extent of Pollution in Planet-bearing Stars
Preliminary observational findings suggest a deficiency of short-period hot Jupiters around post-main-sequence (G giant and subgiant) stars, although the total fraction of them with known planetsExpand
Fermi's Paradox - The Last Challenge For Copernicanism?
We review Fermi's paradox (or the 'Great Silence' problem), not only arguably the oldest and crucial problem for the Search for ExtraTerrestrial Intelligence (SETI), but also a conundrum of profoundExpand
Probing Structures of Distant Extrasolar Planets with Microlensing
Planetary companions to the source stars of a caustic-crossing binary microlensing events can be detected via the deviation from the parent light curves created when the caustic magnifies theExpand
Transit Detectability of Ring Systems around Extrasolar Giant Planets
We investigate whether rings around extrasolar planets could be detected from those planets' transit light curves. To this end, we develop a basic theoretical framework for calculating andExpand
SUMMARY: The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the efiects of applying generalExpand
