Yeah it’s stuff like this that reinforces my belief that it’s arrogance to think there isn’t intelligent life out there. There are around fourteen million galaxies in that survey.
There are about a hundred million stars in an average galaxy, so that works out to about 1.4 quadrillion stars. 1,400,000,000,000,000. If even a small fraction of them (wild guess, one in ten million?) have planets that could yield intelligent life, that’s still 140 million stars with those types of planets.
And this is a small slice (1%) of the night sky. The numbers are beyond boggling.
