Abstract Motivated by recent developments impacting our view of Fermi’s Paradox (the absence of extraterrestrials and their manifestations from our past light cone), we suggest a reassessment of the problem itself, as well as of strategies employed by the various SETI projects so far. The need for such reassessment is fueled not only by the failure of SETI thus far, but also by great advances recently made in astrophysics, astrobiology, computer science and future studies. As a result, we… Expand
Macroengineering in the Galactic Context: A New Agenda for Astrobiology
We consider the problem of detectability of macro-engineering projects over interstellar distances, in the context of Search for ExtraTerrestrial Intelligence (SETI). Freeman J. Dyson and hisExpand

Astrobiological Phase Transition: Towards Resolution of Fermi’s Paradox
TLDR
A model of an astrobiological phase transition of the Milky Way, based on the concept of the global regulation mechanism(s), shows that the phase-transition model offers a rational motivation for continuation and extension of the present-day Search for ExtraTerrestrial Intelligence (SETI) endeavours.

Extragalactic SETI: The Tully-Fisher relation as a probe of Dysonian astroengineering in disk galaxies
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxies. PotentialExpand
Astroengineering, Dysonian SETI, and naturalism: A new Catch-22
Abstract A methodological problem is inherent in any discussion of extraterrestrial engineering and its detectability: how to distinguish detection signatures of such astroengineering from “natural”,Expand
Three explanations for extraterrestrials: sensible, unlikely, mad
Abstract The Fermi Paradox (or Question) has moved back into central focus. This is for a number of reasons, not least the evidence for both the abundance and antiquity of many extra-solar systems,Expand

Galactic punctuated equilibrium: how to undermine Carter's anthropic argument in astrobiology.
TLDR
It is concluded that drawing far-reaching conclusions about the scarcity of extraterrestrial intelligence and the prospects of the efforts to detect it on the basis of Carter's argument is unwarranted. Expand
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 inExpand

Too early? on the apparent conflict of astrobiology and cosmology
TLDR
This work presents an evolutionary argument countering the apparent inconsistency, and shows how, in the framework of a simplified model, deeper picture of the coupling between histories of intelligent/technological civilizations and astrophysical evolution of the Galaxy, can be achieved. Expand
Does our galaxy have a violent history
Abstract Evidence relating to possible large-scale non-circular motion in our Galaxy is reviewed. It is found that a particular model involving general expansion is perfectly consistent with most ofExpand
Abundance gradients and their evolution in the Milky Way disk
Based on a simple, but fairly successful, model of the chemical evolution of the Milky Way disk, we study the evolution of the abundances of the elements He, C, N, O, Ne, Mg, Al, Si, S, Ar and Fe. WeExpand

In this paper we argue for the possibility that even in the event of a Galaxy teeming with extraterrestrial intelligence (ETI) the probability of receiving recognizable signals from the ETIs may beExpand
A search of the IRAS database for evidence of Dyson Spheres
Abstract One of the forms of astroengineering activity that a very advanced civilization could possibly carry on is the constructions of huge “buildings” in space around the central star.Expand
A search for ‘frozen optical messages’ from extraterrestrial civilizations

Limits from CGRO/EGRET Data on the Use of Antimatter as a Power Source by Extraterrestrial Civilizations
I argue that the existence of cold antimatter in bulk is not permitted by the Standard Model, so that if a gamma-ray signature from antiproton annihilation were to be detected, it must representExpand
Cosmic-ray volleys from the galactic center and their recent impact on the earth environment
It is proposed that outbursts of cosmic ray electrons from the Galactic Center penetrate the Galaxy relatively undamped and are able to have a major impact on the Solar System through their abilityExpand
EARTHS: RARE IN TIME, NOT SPACE?
We compare two recent astrobiological approaches to the solution of the problem of the “Great Silence” (or Fermi’s paradox): the “rare Earth” hypothesis of Ward and Brownlee, and the phase-transitionExpand
The temporal aspect of the drake equation and SETI.
TLDR
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. Expand
