Abstract Non-homogeneous fractal-like colonization processes, where the cluster of visited sites has large voids and grows slowly, could explain the negative results of Search for Extraterrestrial Intelligence (SETI) preserving the possibility of a galactic spanning civilization. Here we present a generalized invasion percolation model to illustrate a minimal colonization process with large voids and delayed colonization. Spatial correlation between unvisited sites, in the form of large empty… Expand
Advanced Aspects of the Galactic Habitability
The aim is to numerically investigate the dynamics of opposed processes of expansion and extinction of life in the Galaxy using a new type of numerical simulation based on 1D probabilistic cellular automaton with very high temporal resolution. Expand
Agent-based modelling of interstellar contacts using rumour spread models
Results of the ABM under several settings suggest that limited SETI searches lead to undiscovered civilizations and it is speculated that rumour spread models can propose another solution to Fermi's Paradox. Expand
The Fermi Paradox and the Aurora Effect: Exo-civilization Settlement, Expansion and Steady States.
We model the settlement of the galaxy by space-faring civilizations in order to address issues related to the Fermi Paradox. We explore the problem in a way that avoids assumptions about the intentExpand
Monte Carlo estimation of the probability of causal contacts between communicating civilizations
This work presents a three-parametric statistical Monte Carlo model of the network of causally connected nodes in a simplified sketch of the Galaxy, and shows that the maximum probability of making a contact occurs when a civilization discovers the required communication technology. Expand


Persistence solves Fermi Paradox but challenges SETI projects
Persistence phenomena in colonization processes could explain the negative results of SETI search preserving the possibility of a galactic civilization. However, persistence phenomena also indicatesExpand
The Fermi paradox: An approach based on percolation theory
If even a very small fraction of the hundred billion stars in the galaxy are home to technological civilizations which colonize over interstellar distances, the entire galaxy could be completelyExpand
Spatial dispersion of interstellar civilizations: a probabilistic site percolation model in three dimensions
Abstract A model of the spatial emergence of an interstellar civilization into a uniform distribution of habitable systems is presented. The process of emigration is modelled as a three-dimensionalExpand
Invasion percolation: new algorithms and universality classes
Employing highly efficient algorithms for simulating invasion percolation (IP), whose execution time scales as O[Mlog(M)] or better for a cluster of M sites, and for determining the backbone of theExpand
Cities and fractals: simulating growth and form
The morphology of cities bears an uncanny resemblance to those dendritic clusters of particles which have been recently simulated as fractal growth processes. This paper explores this analogy, firstExpand
Invasion percolation: a new form of percolation theory
A new kind of percolation problem is described which differs from ordinary percolation theory in that it automatically finds the critical points of the system. The model is motivated by the problemExpand
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
Astrobiological Complexity with Probabilistic Cellular Automata
It is argued that probabilistic cellular automata (PCA) represent the best quantitative framework for modeling the astrobiological history of the Milky Way and its Galactic Habitable Zone and how numerical results could offer a cautious rationale for continuation of practical SETI searches is demonstrated.

Eternity in six hours: Intergalactic spreading of intelligent life and sharpening the Fermi paradox
Abstract The Fermi paradox is the discrepancy between the strong likelihood of alien intelligent life emerging (under a wide variety of assumptions) and the absence of any visible evidence for suchExpand
Fractals and Chaos
This volume brings together a number of distinctive contributions in the areas of fractals, chaos, and the interrelationship between the two domains. These contributions cover a wide variety ofExpand
