“Why We Might Be Alone in the Universe”, a British short (24
minutes) by Cool Worlds, an examination of the “Rare Earth” hypothesis.
He talks about sextillions of stars in the Universe and
multiples of planets thereof.
It all depends on the actual probabilities?
He can’t estimate the probability that a self-replicating system
starts.
Of course if the universe lasts more trillions of years, there
could me much more time for it to start again if it hasn’t.
