Abstract:
AbstractThe number of people able to end Earth's technical civilization has heretofore been small. Emerging dual-use technologies, such as biotechnology, may give similar power to thousands or millions of individuals. To quantitatively investigate the ramifications of such a marked shift on the survival of both terrestrial and extraterrestrial technical civilizations, this paper presents a two-parameter model for civilizational lifespans, i.e. the quantity L in Drake's equation for the number of communicating extraterrestrial civilizations. One parameter characterizes the population lethality

Abstract:
The search for extraterrestrial intelligence on exoplanets is a rich field of conceptual exploration. Author introduces two definitions that could help to narrow down the possibilities that an extraterrestrial civilization may or may not have initiated exploration of its own star system and beyond. It is concluded that in some cases certain extraterrestrial civilizations may not be able to leave their home worlds before their biological extinction, purely because of physical limitations.

Abstract:
AbstractMany reasons for why extraterrestrial intelligences might avoid communications with our civilization have been proposed. One possible scenario is that all civilizations follow the lead of some particularly distinguished civilization. This paper will examine the impact the first successful civilization could have on all other subsequent civilizations within its sphere of influence and the ramifications of this as it relates to the Fermi Paradox. Monte Carlo simulation is used to map the inter-arrival times of early civilizations and to highlight the immense epochs of time that the earli

Abstract:
Astronomers conducting searches for extraterrestrial intelligence (SETI) have long been interested in the history of “first contact” between foreign civilizations as a proxy for extraterrestrial contact and have often employed frontier metaphors and colonial analogies in their pursuit of extraterrestrials. This article shows this language was more than mere rhetoric; drawing from the history of Orientalism and the US frontier, this article investigates SETI’s physical and disciplinary homes, ultimately arguing that, even when attempting to convey universality, SETI scientist’s pursuit of the a

Volcanic super-eruptions that produce >1000 km3 of ejected material and ≥ 1000 Mt (1015g) of stratospheric aerosols and sub-micron dust may be capable of creating global climatic disturbances sufficient to cause a severe setback or crash of modern civilization. Eruptions of similar magnitude are estimated to occur on average about every 50000 to 100000 years, which may be considerably more frequent than impacts by asteroids and comets that could cause similar climatic disasters. Prediction, prevention, and mitigation of global volcanic climatic disasters are potentially more difficult than

AbstractPerspectives and possibilities of search for signals of extraterrestrial civilizations in optical range are discussed. Two criteria of an artificial origin of an optical emission – the variations of its intensity which have a time structure of semiotic character and the presence of narrow laser lines are analyzed. For detection and study of these signals we propose to investigate the astronomical objects under suspection with extremely high time resolution – 10−7s.

Abstract:
Abstract Are we alone? It is a compelling question that human beings have confronted for centuries. The search for extraterrestrial life is a broad range of quests for finding simple forms of life up to intelligent beings in the Universe. The plausible assumption is that there is a chance that intelligent life will be followed by advanced civilization equipped or even dominated by artificial intelligence (AI). In this work, we categorize advanced civilizations (on an equal footing, an AI-dominated civilization) on the Kardashev scale. We propose a new scale known as the space exploration dista

AbstractCognitive universals are concepts that our civilization and technologically advanced extraterrestrial civilizations can easily interpret. The universality of certain mathematically and perceptually based concepts are discussed. It is argued that continuously based concepts are more fertile ground for surmising cognitive universals than discretely based ones, and in particular, one should be suspicious of the use of inductively based numerical concepts, including the totality of natural numbers.

Frank Drake devised the Drake equation to estimate the number of advanced civilizations in the galaxy with the aim of gathering support for SETI (the Search for Extraterrestrial Intelligence). The earliest attempts to detect radio signals from extraterrestrials date back to the 1960s. Paul Allen has funded the Allen Telescope, Array which is dedicated to searching for such signals. When complete it will include 350 radio dishes. The citizen science project SETI@Home allows anyone with a home PC to participate in analysing the data amassed by the SETI project.

Abstract It is argued that if the universe is infinite, as it appears to be, then aliens must exist. If we are one of a multitude of civilizations, then this supports the Copernican worldview. If we are all alone in the vastness of space, then perhaps Aristotle and Ptolemy were somewhat correct. Search-for-extraterrestrial-intelligence proponents tend to argue that the Copernican Principle demands that there be multitudes of other civilizations. However, humankind is hardly ordinary, in that having only in the last century developed the means by which to communicate with extraterrestrials or l
