Jun 15, 2020 suggests there are 36 planets in the Milky Way galaxy, a calculation the experts have dubbed "the Astrobiological Copernican Limit."

The two Astrobiological Copernican limits are that intelligent life forms in less than 5 billion years, or after about 5 billion years - similar to on Earth where a communicating civilization formed after …

DOI: 10.3847/1538-4357/ab8225 The 36 civilizations estimate, per the authors, was arrived at by following the "strong limit" of the Astrobiological Copernican. That figure, however, is conceded as being on the "lower" end of “This type of life has developed in a metal-rich environment.” As explained in the study published in The Astrophysics Journal and its press release, that’s the simple strong or upper Astrobiological Copernican Limit – a star showing sufficient metal content to make a safe assumption that its life-bearing planets also have the metals needed to evolve enough to have intelligence.

The other is the Strong Condition in which life must form between 4.5 to 5.5 Gyr, as on Earth.

First author of the study, Tom Westby, explained how the Astrobiological Copernican Limit simplified previous estimations which relied on “making guesses of values relating to life, whereby opinions about such matters vary quite substantially.” The more objective methodology used here is based on two central limits.

The calculation, what the researchers have dubbed Astrobiological Copernican Limit, aims to look at evolution on a cosmic scale rather than an Earth-centric one, and gets its namesake from Nicolaus Copernicus, the astronomer who first formulated a model of the universe that placed the Sun rather than Earth at its center.

Named for Copernican heliocentrism, it is a working assumption that arises from a modified cosmological extension of Copernicus's argument of a moving Earth.

Named for Copernican heliocentrism, it is a working assumption that arises from a modified cosmological extension of Copernicus's argument of a moving Earth. The Astrobiological Copernican Strong limit is that life must form between 4.5 to 5.5 billion years, as on Earth, while the weak limit is that a planet takes at least 4 billion years to form life There are two variations of the Astrobiological Copernican Limit. To have a “weak” limit suggests that at least 5 billion years are needed for a habitable planet to develop life, whereas a RECENT ARTICLES “Life Beyond Our Universe?” –The Eerie Implications of Infinite Space March 31, 2021 “The Galaxy Report” –Opt-In for Our Free Weekly Newsletter March 31, 2021 At one extreme is the Weak Astrobiological Copernican scenario—such that a planet forms intelligent life sometime after 5 Gyr, but not earlier. The other is the Strong Astrobiological Copernican scenario in which life must form between 4.5 and 5.5 Gyr, as on Earth. Tom Westby, Christopher J. Conselice.

The other is the ‘Strong’ limit where life formed between 4.5 billion and 5 billion years years ago. 2020-06-15 The Astrobiological Copernican limits come in two forms. One is the ‘weak’ limit, which suggests that intelligent life forms on a planet any time after 5 billion years. Astrobiology, formerly known as exobiology, is an interdisciplinary scientific field concerned with the origins, early evolution, distribution, and future of life in the universe.Astrobiology considers the question of whether extraterrestrial life exists, and if it does, how humans can detect it..
