Xenoarchaeology

From Wikipedia, the free encyclopedia

Xenoarchaeology, a branch of xenology dealing with extraterrestrial cultures, is a hypothetical form of archaeology that exists mainly in works of science fiction. The field is concerned with the study of material remains to reconstruct and interpret past life-ways of alien civilizations. Xenoarchaeology is not currently practiced by mainstream archaeologists due to the current lack of any material for the discipline to study.

Etymology[]

The name derives from Greek xenos (ξένος) which means 'stranger, alien', and archaeology 'study of ancients'.

Xenoarchaeology is sometimes called astroarchaeology or exoarchaeology, although some would argue that the prefix exo- would be more correctly applied to the study of human activities in a space environment.[1]

Other names for xenoarchaeology, or specialised fields of interest, include Probe SETI (Search for Extra-Terrestrial Intelligence), extraterrestrial archaeology, space archaeology, SETA (Search for Extra-Terrestrial Artifacts), Dysonian SETI, Planetary SETI, SETT (Search for Extra-Terrestrial Technology), SETV (Search for Extra-Terrestrial Visitation),[2] extraterrestrial anthropology, areoarchaeology and selenoarchaeology.[3]

Justification[]

It is arguably the case that, due to the immense distances between stars, any evidence we discover of extraterrestrial intelligence, whether it be an artifact or an electromagnetic signal, may come from a long-vanished civilization. Thus the entire SETI project can be seen as a form of archaeology.[4][5][6] Additionally, due to the extreme age of the universe, there may be a reasonable expectation for astrobiology research to produce evidence of extinct alien life prior to the discovery of alien life itself.[7]

The study of alien cultures might offer us glimpses into our own species' past or future development.[8][9]

Vicky Walsh argued for the existence of "exo-artifacts" using the principle of mediocrity and the Drake equation. She proposed that a theoretical and speculative field of archaeology be established in order to test outlandish claims, and to prepare for a time when undeniably extraterrestrial artifacts needed to be analysed. "If it is possible to construct an abstract archaeology that can be tested and refined on earth and then applied to areas beyond our planet, then the claims for ETI remains on the moon and Mars may really be evaluated in light of established archaeological theory and analysis".[10]

Ben McGee similarly proposed the creation of a set of interdisciplinary, proactive xenoarchaeological guidelines, arguing that identifying suspected artifacts of astrobiology is all that is required to justify establishing a methodology for xenoarchaeology. He emphasized the necessity of proactive xenoarchaeological work in order to avoid future bias, mischaracterization, and information mismanagement, and he cites three scenarios under which such a methodology or set of guidelines would be useful, those being "remote sensing" of a potential xenoarchaeologial artifact, encountering an artifact during "human exploration," and "terrestrial interception" of an artifact.[7]

Greg Fewer has argued that archaeological techniques should be used to evaluate alleged UFO landing or crash sites, such as Roswell.[11]

History[]

The origins of the field have been traced[12] to theories about a hypothetical Martian civilization based on observations of what were perceived as canals on Mars. These theories, of which Percival Lowell was the most famous exponent, were apparently inspired by a mistranslation of a quote by Giovanni Schiaparelli.

The 1997 Theoretical Archaeology Group conference featured a session on "archaeology and science fiction".[13]

The 2004 annual meeting of the American Anthropological Association featured a session Anthropology, Archaeology and Interstellar Communication.[14]

Planetary SETI[]

Planetary SETI is concerned with the search for extraterrestrial structures on the surface of bodies in the Solar System. Claims for evidence of extraterrestrial artifacts can be divided into three groups, the Moon, Mars, and the other planets and their satellites.[3]

Examples of sites of interest include the "bridge" sighted in the Mare Crisium in 1953, and the "Blair Cuspids", "an unusual arrangement of seven spirelike objects of varying heights" at the western edge of the Mare Tranquillitatis, photographed by in Lunar Orbiter 2 on 20 November 1966.[15] In 2006, Ian Crawford proposed that a search for alien artifacts be conducted on the Moon.[16]

Percival Lowell's mistaken identification of Martian canals[17] was an early attempt to detect and study an alien culture from its supposed physical remains.[citation needed] More recently, there was interest in the supposed Face on Mars, an example of the psychological phenomenon of pareidolia.[18]

The Society for Planetary SETI Research is a loose organization of researchers interested in this field. The organization does not endorse any particular conclusions drawn by its members on particular sites.[19]

Probe SETI, or SETA[]

Further information: Bracewell probe

A great deal of research and writing has been done, and some searches conducted for extraterrestrial probes in the Solar System.[20] This followed the work of Ronald N. Bracewell.

Robert Freitas,[21][22][23] Christopher Rose and Gregory Wright have argued that interstellar probes can be a more energy-efficient means of communication than electromagnetic broadcasts.[24]

If so, a solarcentric Search for Extraterrestrial Artifacts (SETA)[25] would seem to be favored over the more traditional radio or optical searches. Robert A. Freitas coined the Term SETA in the 1980s.[26]

On the basis that the Earth-Moon or Sun-Earth libration orbits might constitute convenient parking places for automated extraterrestrial probes, unsuccessful searches were conducted by Freitas and Valdes.[27][28]

Dysonian SETI[]

In a 1960 paper, Freeman Dyson proposed the idea of a Dyson sphere, a type of extraterrestrial artifact able to be searched for and studied at interstellar distances. Following that paper, several searches have been conducted.[29]

In a 2005 paper, Luc Arnold proposed a means of detecting smaller, though still mega-scale, artifacts from their distinctive transit light curve signature.[30] (see Astroengineering).

Fringe theories[]

A subculture of enthusiasts studies purported structures on the Moon or Mars. These controversial "structures" (such as the Face on Mars) are not accepted as more than natural features by most scientists, examples of the pareidolia phenomenon.

Palaeocontact or ancient astronaut theories, espoused by Erich von Däniken and others, are further examples of fringe theories. These claim that the Earth was visited in prehistoric times by extraterrestrial beings.

Science fiction[]

Xenoarchaeological themes are common in science fiction. Works about the exploration of enigmatic extraterrestrial artifacts have been satirically categorized as Big Dumb Object stories.

Some of the more prominent examples of xenoarchaeological fiction include Arthur C. Clarke's novel Rendezvous with Rama, H. Beam Piper's short story Omnilingual, and Charles Sheffield's Heritage Universe series.
