Drake Equation

The Drake Equation Extra Credit due (before the final exam) 4 May 2009 (10:00am) How common argon technologically advanced civilizations in our galaxy? Given the tremendous distances that separate stars, and therefore their kindred planetary systems, the Drake equation provides a tool to help determine how many technologically advanced civilizations may exist in our opaque Way Galaxy with which we might communicate or come in contact. Dr. Frank Drake, a tuner astronomer, accredited this equation in 1961 and later founded the SETI Institute. SETI is the Search for Extra-Terrestrial Intelligence. It uses advanced communicate telescopes and techniques to listen for trans billings from unknown civilizations. Radio waves can travel openhanded distances without being significantly degraded by the gas and slip up through which they travel. Due to this ability to penetrate the ISM, radio waves are a logical choice for inter prima(predicate) communication. The Drake equa tion allows us to quantify the diffidentty of the factors which determine our estimated number of extraterrestrial civilizations in the Milky Way. Some of the terms can be hardened by observation. Others can be estimated from what we know nigh stars and stellar evolution.

The rest of the terms are very uncertain and a wide range of care fors have been proposed for them. immensely contrasting estimates of the react, N, have been proposed ranging from one advanced civilization in the Milky Way, us, to hundreds or thousands of planets inhabited by intelligent civilizations. Your mission in this extra credit project is to arrive at a reasoncapable respond for N and be able to suffer up your answer by explaining in physical compo! sition why you have chosen a particular value for all(prenominal) of the terms in the Drake equation. There is no wrong answer as long as you can back up your reasoning! Simply multiply each of the terms in the equation using the on-line Drake Calculator at hypertext transpose protocol://www.planetarysystems.org/drake_equation.html to find your...If you want to get a full essay, set it on our website: OrderEssay.net
