Extraterrestrial intelligent beings do not exist
Abstract
The singularity vs. the plurality of inhabited worlds in the universe is debated. Attention is given to astrophysical constraints on the evolution of intelligent species and to motivations for interstellar communication and exploration. It is argued that it is plausible that there is only one inhabited planet in the universe.
