The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. [ 1 ] [ 2 ] [ 3 ] The equation was formulated in 1961 by Frank Drake , not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 8 February 2025. Discrepancy of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy ...
The Rare Earth equation is Ward and Brownlee's riposte to the Drake equation. It calculates , the number of Earth-like planets in the Milky Way having complex life forms, as: According to Rare Earth, the Cambrian explosion that saw extreme diversification of chordata from simple forms like Pikaia (pictured) was an improbable event.
Drake equation – Estimate of extraterrestrial civilizations; Anthropic principle – Hypothesis about sapient life and the universe; Global catastrophic risk – Hypothetical global-scale disaster risk; Goldilocks principle – Analogy for optimal conditions; Inverse gambler's fallacy – Formal fallacy of Bayesian inference
The Search for Life: The Drake Equation is a 2010 BBC Four television documentary about that equation, which is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. [1] [2] It was presented by Dallas Campbell.
[1] [4] The Drake equation has been described as the "second most-famous equation in science", after E=mc 2. [9] In 1963, Drake served as section chief of Lunar and Planetary Science at the Jet Propulsion Laboratory. He returned to Cornell in 1964, this time as a member of the faculty (academic staff), where he would spend the next two decades ...
Without getting overly technical, the idea behind quantum is that these computers should have the ability to process data and derive solutions to problems that could take years or even decades to ...
The dark forest hypothesis is the conjecture that many alien civilizations exist throughout the universe, but they are both silent and hostile, maintaining their undetectability for fear of being destroyed by another hostile and undetected civilization. [1]
