Uniformity of motive
Encyclopedia
In astrobiology
, the Uniformity of Motive theory suggests that any civilization in the universe
would go through similar technological steps in their development. This theory supports the idea that at some point in their history, advanced alien civilizations would use the electromagnetic
medium for communications, and thus would emit radio waves that could be detected by projects such as SETI
.
The fact that no artificial EM band communications have ever been detected supports the Fermi Principle, which in conjunction with the Uniformity of Motive theory, and Occam's razor
suggests that a civilization that uses this medium is a unique occurrence in Earth's region of the Milky Way Galaxy and perhaps the universe.
Astrobiology
Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. This interdisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry,...

SETI
The search for extraterrestrial intelligence is the collective name for a number of activities people undertake to search for intelligent extraterrestrial life. Some of the most well known projects are run by the SETI Institute. SETI projects use scientific methods to search for intelligent life...

Occam's razor
Occam's razor, also known as Ockham's razor, and sometimes expressed in Latin as lex parsimoniae , is a principle that generally recommends from among competing hypotheses selecting the one that makes the fewest new assumptions.-Overview:The principle is often summarized as "simpler explanations...
