by David Solomonoff

“Only a very small fraction of exoplanets will just happen to be randomly aligned with our line of sight so we can see them transit. But all of the thousand stars we identified in our paper in the solar neighborhood could see our Earth transit the Sun, calling their attention.”

“If we found a planet with a vibrant biosphere, we would get curious about whether or not someone is there looking at us too.”
