Drake equation: L f f f n f R N c i l e p s × × × × × × = where: N = the number of civilizations in our galaxy with which we might expect to be able to communicate at any given time R s = Rate of star formation in our galaxy f p= is the fraction of those stars that have planets n e= Number of earth like planets in each system f l= Fraction of earth like planets producing life f i= Fraction of life where intelligence develops f c= Fraction of intelligent species interested in communicating L = Lifetime of such a civilization Drake’s equation is an estimate of the different places or the planets where the life might sustain in our galaxy. After solving the drake’s equation it gives an approximate number of planets where life might exist. Due to lack in technological development this equation helps us by giving a good estimation. 2.) Yes. I expect to see life elsewhere in the universe in the next hundred years. If we roll back a
