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 intent and motivation of any exo-civilization seeking to settle other planetary systems. We first consider the speed of an advancing settlement via probes of finite velocity and range to determine if the galaxy can become inhabited with space-faring civilizations on timescales shorter than its age. We also… Expand
Minimal Conditions for Survival of Technological Civilizations in the Face of Stellar Evolution
The ease of interstellar rocket travel is an issue with implications for the long-term fate of our own and other civilizations and for the much-debated number of technological civilizations in theExpand
Triggering A Climate Change Dominated"Anthropocene": Is It Common Among Exocivilizations?
We seek to model the coupled evolution of a planet and a civilization through the era when energy harvesting by the civilization drives the planet into new and adverse climate states. In this way weExpand
A probabilistic analysis of the Fermi paradox in terms of the Drake formula: the role of the L factor
In evaluating the number of technological civilizations N in the Galaxy through the Drake formula, emphasis is mostly put on the astrophysical and biotechnological factors describing the emergence ofExpand
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
Galactic Traversability: A New Concept for Extragalactic SETI
Interstellar travel in the Milky Way is commonly thought to be a long and dangerous enterprise, but are all galaxies so hazardous? I introduce the concept of galactic traversability to address thisExpand
The Dynamics of the Transition from Kardashev Type II to Type III Galaxies Favor Technosignature Searches in the Central Regions of Galaxies
We present a video of a simulation showing the expansion front of a technological species settling a Milky Way-like galaxy, created using the model described in Carroll-Nellenback et al. ItExpand
Near-Term Self-replicating Probes -- A Concept Design
It is concluded that small-scale, partially self-replicating probes are feasible near-term, and their benefits would play out in exploration missions requiring roughly more than more than a dozen of probes. Expand
The Breakthrough Listen Search For Intelligent Life Near the Galactic Center. I.
A line of sight toward the Galactic Center (GC) offers the largest number of potentially habitable systems of any direction in the sky. The Breakthrough Listen program is undertaking the mostExpand
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. Expand


The Fermi Paradox, Self-Replicating Probes, and the Interstellar Transportation Bandwidth
It has been widely acknowledged that self-replicating space-probes (SRPs) could explore the galaxy very quickly relative to the age of the galaxy. An obvious implication is that SRPs produced byExpand
Discrete calculations of interstellar migration and settlement
Abstract Monte Carlo calculations of the expansion of space-faring civilizations are presented for a wide range of values of the population growth coefficient (α) and emigration coefficient (γ). EvenExpand
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
the Ĝ infrared search for extraterrestrial civilizations with large energy supplies. II. Framework, strategy, and first result
We describe the framework and strategy of the Ĝ infrared search for extraterrestrial civilizations with large energy supplies, which will use the wide-field infrared surveys of WISE and Spitzer toExpand
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
SETI turns 50: five decades of progress in the search for extraterrestrial intelligence
The 1959 Nature article by Giuseppe Cocconi and Phil Morrison1 provided the theoretical underpinnings for SETI, accompanied in 1960 by Project Ozma2, the first radio search for signals by Frank DrakeExpand
Light of the Stars: Alien Worlds and the Fate of the Earth
The great American philosopher, poet, educator, and an early eco-activist Ralph Waldo Emerson happened to be in Paris during the tumultuous days of the 1848 liberal revolutions across Europe. UponExpand
How Much SETI Has Been Done? Finding Needles in the n-Dimensional Cosmic Haystack
This article develops the metaphor of the multidimensional "Cosmic Haystack" through which SETI hunts for alien "needles" into a quantitative, eight-dimensional model and performs an analytic integral to compute the fraction of this haystack that several large radio SETI programs have collectively examined.

The fermi paradox is neither Fermi's nor a paradox.

The Fermi paradox is seen by some as an authoritative objection to searching for evidence of extraterrestrial intelligence--cited in the U.S. Congress as a reason for killing NASA's SETI program on one occasion--but evidence indicates that it misrepresents Fermani's views, misappropriates his authority, deprives the actual authors of credit, and is not a valid paradox.

On the likelihood of non-terrestrial artifacts in the Solar System
Abstract Extraterrestrial technology may exist in the Solar System without our knowledge. This is because the vastness of space, combined with our limited searches to date, implies that any remoteExpand
