Physical Science. The Drake Equation, also known as the Green Bank Equation after the conference where it was first presented, is a formula created by American physicist Frank Drake to estimate the number of intelligent alien civilizations which exist in the Milky Way and which, given sufficient technology and time, humanity might one day be able to communicate with. Although it takes the form of a mathematical equation, it is important to note that Drake never intended it to be solved precisely. Instead, he offered it as a sort of thought-experiment, taking into account all of the factors which would go into the likelihood of intelligent civilizations existing elsewhere in the universe:. In his work, Drake assumed that all life would emerge independently, and naturally, through evolution. As a result, one can imagine the universe as a collection of billions of sets of dice, all of them being rolled over and over again.

The Drake Equation is used to estimate the number of communicating civilizations in our galaxy, or more simply put, the odds of finding intelligent life in the Milky Way. First proposed by radio astronomer Frank Drake in , the equation calculates the number of communicating civilizations by multiplying several variables. The challenge at least for now is that astronomers don't have firm numbers on any of those variables, so any calculation of the Drake Equation remains a rough estimate for now. There have been, however, discoveries in some of these fields that give astronomers a better chance of finding the answer. These stars, however, are red dwarfs that might be too volatile for life. More study is needed to understand where life might be possible, and whether it could persist long enough to communicate with other civilizations. Astronomers certainly could imagine the existence of other planets outside the solar system in , but it took until until the first confirmed exoplanet was found around a main-sequence star Called 51 Pegasi b, the discovery ushered in a new era when astronomers were able to track down many other planets across the universe.
The Drake Equation – What are the Chances of Extraterrestrial Life?
The mathematics of dating is a series of formulae of increasing comlpexity, designed to describe various variables involved in dating and romance. The Standard Creepiness Rule states that if we define an individual's age as x , said individual should not date anyone under:. Now, this boring graph shows only the ages available. However does not take into account either the population of each age bracket something which would require individual research , nor the percentage of those who are single in each age bracket. It has been suggested however that graphing these equations will help boost your self-esteem, and generally give you something nice to put on your wall.
In this lecture and the subsequent lectures, we examine the more-speculative side of the search for life: the search for extraterrestrial intelligence SETI. This lecture focuses on the Drake Equation, a useful tool in this endeavour. So far, we have considered extrasolar life to be passive : it is something which sits there, waiting for us to discover it through our own endeavours. However, suppose that some extrasolar life is sentient, intelligent, and technologically advanced. Then, this life may be making attempts to signal its presence, and to contact other lifeforms in the Milky Way galaxy.
