That’s roughlya million billion billion planets. The enormity of this number means it’s probably safeto assume that there are many many *many* other planets with life - even intelligentlife.And this, together with some basic physics and fancy statistics, implies it’s morelikely that species of intelligent extraterrestrials w...
