As unlikely as it seems in a galaxy with hundreds of billions of stars and as many as 40 billion Earth-size planets in habitable zones, we could be alone. There is no intelligent life besides us. This assumes, of course, that humans count as intelligent. Intelligent species lack advanced technology. Currently, astronomers utilize radio telescopes to listen intently to the night sky. Intelligent life self-destructs.

Whether via weapons of mass destruction, planetary pollution, or manufactured virulent disease, it may be the nature of intelligent species to commit suicide, existing for only a short time before winking out of existence. The universe is a deadly place. On cosmic timescales — think billions of years — life may be fleeting.

Space is big. Eighty years. As previously mentioned, space is big, so there are tons of regions to listen for alien signals. Alien technology may be too advanced. Radio technology may be commonplace here on Earth, but on far-flung worlds, alien societies may have graduated to more advanced communication technologies, like neutrino signals. Nobody is transmitting. Instead, everybody may be listening. In fact, if aliens have radio telescopes similar to what we have on Earth, our television and radio broadcasts would only be detectable up to 0. Earth is deliberately not being contacted. Just like in Star Trek, advanced alien societies may enforce rules that limit contact only to species that attain a lofty degree of technological or cultural evolution.
