The Number of Civilizations In Space and The Drake Equation

The Number of Civilizations In Space and The Drake Equation


As we near the Fall Conference called “PARACON”, attendees need to know why we are so focused on UFOs for this event.  Different civilizations beyond ours are projected to be in existence in the Milky Way.  The following information comes from the article “The Drake Equation” on the site,

An amazing mathematician, Dr. Frank Drake, in 1961, wrote an equation that predicts the number of civilizations that are at our level or higher in the Milky Way cosmic system. His famous equation is: N = R x fp x ne x fl x fi x fc x 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.

At the point when the equation is finished it would appear that this, N = 7 × 1 × 0.2 × 0.13 × 1 × 0.2 × 109 = 36.4 million (Wiki source) planets with civilizations.

If this information intrigues you, then read the whole article that expands the ideas and the discussions around life beyond Earth.

Walk in peace!
