Drako's theory :
- average amount of new stars per year in our galaxy - 50
- stars with planets - 50% of all stars
- habitable planets - averagely 4 out of 10 are
- living planets - life can form in 90% of habitable planets
- intelligent life form - maybe only in 10% of living planets will form
intelligent being
- communicating being - maybe 10% of intelligent life forms will find a
way for interstellar communication
- period of civilization's existence - averagely 10000 years
Due to these facts we can await that in our galaxy exist
50 x 0.5 x 0.4 x 0.9 x 0.1 x 0.1 x 10000 = 900 alien civilzations, with which we can theoretically communicate.
But well, it's just a theory.
Anyway if we are about to find out an intelligent life form at other planets far away, it will be way stranger being than in any of our imaginations.
