Went for my evening walk re-listening to the last astronomy lecture. It was about the different theories of the big bang and the universes that could have happened if it was weighted differently than the one we live in. Professor Bloom also discussed the prospects of intelligent life in other solar systems using astronomer Frank Drake’s famous equation N = R Fp Ne Fl Fi Fc L: (I copied the following from an online source)
N = the number of civilizations with whom we can connect
R = the rate of star formation (10 stars per year in our galaxy)
Fp = the fraction of stars that develop planets
Ne = planets suitable for life
Fl = planets that actually develop life
Fi = planets that develop life that is intelligent
Fc = civilizations that communicate
L = civilizations at the stage at which communication can occur
So you just plug in the numbers and depending on what numbers you use the results change in favor for or against intelligent life. Interesting!
