Kardashev presented for the first time a classification of civilizations according to their level of energy consumption in an article entitled Transmission of Information by Extraterrestrial Civilizations, published in 1964 first in Russian in the March-April issue of the Astronomicheskii Zhurnal, then in English in the September–October 1964 issue of the Soviet Astronomical Journal. Origin of the classification First publication (1964) Projection of the Kardashev scale to 2040 based on data from the International Energy Agency World Energy Outlook However, in part thanks to such searches, unusual objects, now known to be either pulsars or quasars, were identified. Two more articles followed: "On the Inevitability and the Possible Structure of Super Civilizations" and "Cosmology and Civilizations", published in 19, respectively the Soviet astronomer proposed ways to detect super civilizations and to direct the SETI (Search for Extra Terrestrial Intelligence) programs.Ī number of scientists have conducted searches for possible civilizations, but with no conclusive results. In a second article, entitled "Strategies of Searching for Extraterrestrial Intelligence", published in 1980, Kardashev wonders about the ability of a civilization, which he defines by its ability to access energy, to sustain itself, and to integrate information from its environment. A Type III civilization is able to capture all the energy emitted by its galaxy, and every object within it, such as every star, black hole, etc.A Type II civilization can directly consume a star's energy, most likely through the use of a Dyson sphere.Hypothetically, they should also be able to control natural events such as earthquakes, volcanic eruptions, etc. A Type I civilization is able to access all the energy available on its planet and store it for consumption.He proposed a classification of civilizations into three types, based on the axiom of exponential growth: Starting from a functional definition of civilization, based on the immutability of physical laws and using human civilization as a model of extrapolation, Kardashev's initial model was developed. Kardashev first outlined his scale in a paper presented at the 1964 Byurakan conference in Armenia, a scientific meeting that reviewed the Soviet radio astronomy space listening program. Various extensions of the scale have since been proposed, including a wider range of power levels (Types 0, IV, and V) and the use of metrics other than pure power (e.g., computational growth or food consumption). The scale is hypothetical, and refers to energy consumption on a cosmic scale. The measure was proposed by Soviet astronomer Nikolai Kardashev (1932–2019) in 1964 and was named after him. The Kardashev scale ( Russian: Шкала́ Кардашёва, romanized: Shkalá Kardashova) is a method of measuring a civilization's level of technological advancement based on the amount of energy it is capable of using. The search for exoplanets on which extraterrestrial civilizations could be found is one of the many missions of the VLT.
