The Chances for Intelligent Lift? The Chances for (Intelligent) Life?  Is there intelligent life elsewhere?  How could we contact them?  How will humanity evolve?

The Habitable Zone Distance around our Sun supporting Life Distance around our Sun supporting Life Originally narrow, between Venus & Mars Originally narrow, between Venus & Mars Depends on planet size, capability of life to survive in various conditions Depends on planet size, capability of life to survive in various conditions Now – Venus to Jupiter? Even Moons of giant planets? Now – Venus to Jupiter? Even Moons of giant planets?

Drake’s Equation N = R * x f planet x n e x f life x f intell x f civ x L N = # intelligent, transmitting civilizations N = # intelligent, transmitting civilizations R * = # stars formed/year R * = # stars formed/year f planet = fraction of stars w/ planets f planet = fraction of stars w/ planets n e = # of planets/system that can support life n e = # of planets/system that can support life f life = fraction that develop life f life = fraction that develop life f intell = fraction with life that becomes intelligence f intell = fraction with life that becomes intelligence f civ = fraction that produce interstellar communications capability f civ = fraction that produce interstellar communications capability L = “Lifetime” of how long they try to communicate L = “Lifetime” of how long they try to communicate

Drake’s Equation Example N = R * x f planet x n e x f life x f intell x f civ x L R * = 40 (400 Billion stars in our galaxy about 10 BY old) R * = 40 (400 Billion stars in our galaxy about 10 BY old) f planet = 50% f planet = 50% n e = 0.5 n e = 0.5 f life = 1 (optimistic – we did, so others could too!) f life = 1 (optimistic – we did, so others could too!) f intell = 1 f intell = 1 f civ = 1 f civ = 1 L = 10,000 years L = 10,000 years N =100,000 communicating, intelligent civilizations in the Milky Way alone! N =100,000 communicating, intelligent civilizations in the Milky Way alone!
