Now the usefulness of this is questionable as the rare earth hypothesis uses conservative values leading to a number less than one. But a more favourable set of criteria set the number at 15,000,000 species.
So we actually don’t know with certainty if the likelihood of intelligent life is rare on a universe level scale. |
I think it's worthwhile to think of this question also in terms of the sheer size of the universe. Even if the universe is teeming with life, it is all so far away that we have no good reason of ever imagining that we could know one way or the other. It seems reasonable to conclude that nothing travels faster than light, and even at light speed the nearest star is more than a four-year journey away.
