Advanced Civilization Calculator – Drake Equation.
See how many civilizations are out there with advanced civilization calculator. Based on the Drake Equation the advanced civilization calculator is exactly the tool you need to find it out.
Ever wondered how many advanced civilizations might there be out there? Given the vastness of space populated by trillions of galaxies, each consisting of billions of star systems – how do you even approach the problem? The number of digits involved makes the head spin and the complexity of calculation boggles the mind. There is, however, a tool – an advanced civilization calculator – that makes this calculation relatively simple.
Dr Frank Drake, currently a member of the Board of the SETI Institute (Search for Extraterrestrial Intelligence), came up with the solution to the problem while working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West Virginia. The Drake Equation, as it has become known, was first presented by Drake in 1961 and identifies specific factors thought to play a role in the development of such civilizations. Although there is no unique solution to this equation, it is a generally accepted tool used by the scientific community to examine these factors.
The equation is usually written:
N = R* • fp • ne • fl • fi • fc • L
Where,
N = The number of civilizations in The Milky Way Galaxy whose electromagnetic emissions are detectable.
R* =The rate of formation of stars suitable for the development of intelligent life.
fp = The fraction of those stars with planetary systems.
ne = The number of planets, per solar system, with an environment suitable for life.
fl = The fraction of suitable planets on which life actually appears.
fi = The fraction of life bearing planets on which intelligent life emerges.
fc = The fraction of civilizations that develop a technology that releases detectable signs of their existence into space.
L = The length of time such civilizations release detectable signals into space.
Within the limits of our existing technology, any practical search for distant intelligent life must necessarily be a search for some manifestation of a distant technology. In each of its last four decadal reviews, the National Research Council has emphasized the relevance and importance of searching for evidence of the electromagnetic signature of distant civilizations.
Besides illuminating the factors involved in such a search, the Drake Equation is a simple, effective tool for stimulating intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for making us realize how much we are a part of that universe. A key goal of the SETI Institute is to further high quality research that will yield additional information related to any of the factors of this fascinating equation.
