Abstract 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 civilizations resident in the Milky Way, and by the Fermi Paradox, glibly stated as: ‘If they are there, where are they?’. Both rely on using average values of key parameters, such as the mean signal lifetime of a communicating civilization. A more accurate answer must take into account the distribution of… 

A Statistical Estimation of the Occurrence of Extraterrestrial Intelligence in the Milky Way Galaxy

This model estimates the occurrence of ETI, providing guidance on where to look for intelligent life in the Search for ETI with a set of criteria, including well-established astrophysical properties of the Milky Way.

Communicating extraterrestrial intelligence (CETI) interaction models based on the Drake Equation

The Drake Equation has proven fertile ground for speculation about the abundance, or lack thereof, of communicating extraterrestrial intelligences (CETIs) for decades. It has been augmented by

A stochastic process approach of the drake equation parameters

Abstract The number N of detectable (i.e. communicating) extraterrestrial civilizations in the Milky Way galaxy is usually calculated by using the Drake equation. This equation was established in

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.

Abstract The number of habitable planets in the Milky Way and its temporal variation are major unknowns in the nascent fields of astrobiology and Search for ExtraTerrestrial Intelligence studies. All

Numerical testing of the Rare Earth Hypothesis using Monte Carlo realization techniques

Abstract The Search for Extraterrestrial Intelligence (SETI) has thus far failed to provide a convincing detection of intelligent life. In the wake of this null signal, many ‘contact-pessimistic’

Artificial versus biological intelligence in the Cosmos: clues from a stochastic analysis of the Drake equation

A statistical investigation shows that the Drake equation delivers robust predictions of the likelihood that the prevalent form of intelligence in the universe is artificial rather than biological, which far exceeds the likelihood of biological intelligence.

New numerical determination of habitability in the Galaxy: the SETI connection

Abstract In this paper, we determine the habitability of Sun-like stars in the Galaxy using Monte Carlo simulations, which are guided by the factors of the Drake Equation for the considerations on

Extending Galactic Habitable Zone Modeling to Include the Emergence of Intelligent Life.

The findings suggest that the inner Galaxy should logically be a prime target region for searches for extraterrestrial intelligence and that any civilizations that may have emerged there are potentially much older than the authors' own.

Demography of galactic technosignatures

Probabilistic arguments about the existence of technological life beyond Earth traditionally refer to the Drake equation to draw possible estimates of the number of technologically advanced



The temporal aspect of the drake equation and SETI.

It is shown that the Drake equation tacitly relies on unverified assumptions on both the physicochemical history of the authors' galaxy and the properties of advanced intelligent communities to form prerequisites for quantification of therake equation parameters.


SUMMARY: We investigate the efiects of correlated global regulation mecha-nisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distributionof hypothetical inhabited planets, using


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 general

An Astrophysical Explanation for the Great Silence

An astrophysical model is proposed to answer Fermi's question. Gamma-ray bursts have the correct rates of occurrence and plausibly the correct energetics to have consequences for the evolution of

A mechanism for interstellar panspermia

Metre-sized boulders ejected from the Earth by large impacts are destroyed through collisions and erosion by impacting zodiacal cloud dust particles. The time-scale for such disintegration in a dense

Five- or six-step scenario for evolution?

Abstract The prediction that (due to the limited amount of hydrogen available as fuel in the Sun) the future duration of our favourable terrestrial environment will be short (compared with the

An Estimate of the Age Distribution of Terrestrial Planets in the Universe: Quantifying Metallicity as a Selection Effect

Abstract Planets such as the Earth cannot form unless elements heavier than helium are available. These heavy elements, or “metals”, were not produced in the Big Bang. They result from fusion inside

Interstellar transfer of planetary microbiota

Panspermia theories require the transport of micro-organisms in a viable form from one astronomical location to another. The evidence of material ejection from planetary surfaces, of dynamical orbit

Mass models of the Milky Way

The proposition that flat rotation curves arise because galaxies have physically distinct haloes rather than outwards-increasing mass-to-light ratios is called into question.
