The Search For Extra-Terrestrial Intelligence (SETI) and Whether to Send "Messages" (METI)

Persistent null results from the Search for Extra-terrestrial Intelligence do not invalidate continuing the search, but they do raise questions about long-held assumptions over how we search.

The Digital Revolution will make human civilization invisible to Extraterrestrial Search -- Frank Drake. Some of the world's leading astronomers -- including Great Britain's astronomer royal, Sir Martin Rees -- believe advanced extraterrestrial civilizations, rather than using different radio waves or visible light to signal, may be using an entirely...

What are the chances of intelligent life in the universe? What is SETI, and what is its mission? What technologies form the basis of this search? What are the more advanced and successful technological breakthroughs in the recent years that have enhanced the SETI approach? What is the SETI@Home project and what is the meaning of volunteer “gridware”? These questions answered by: David Brin - Scientist, Futurist and  Author

Xenology: The Science of Asking Who's Out  In the 1960s, Stellar astronomers faced unsettling data from new classes of objects called "quasars" and "radio galaxies."And now an abundance of exoplanets. Still, the greatest intellectual challenge to the worldview of modern astronomers came in the early sixties, not because of new space probes, telescopes, and computers but because of an idea.

Earth's "foreign policy." What are the obstacles toward interstellar travel? Should humanity announce its presence to the cosmos?

I debated British METI enthusiast Nick Pope on the Canadian Broadcasting System regarding the wisdom of shouting “yoohoo” messages at the cosmos. It was a fun and lively radio show. You can listen here.

Singularities and Nightmares: Extremes of Optimism and Pessimism About the Human Future:In order to give you pleasant dreams tonight, let me offer a few possibilities about the days that lie ahead — changes that may occur within the next twenty or so years, roughly a single human generation. Possibilities that are taken seriously by some of today’s best minds. Potential transformations of human life on Earth and, perhaps, even what it means to be human.

Speculating about extraterrestrial civilization boils down to asking “what are the factors that went into making us?” It spans every science,.

Is there intelligent life in the cosmos? Speculating about extraterrestrial life spans sciences, from understanding stellar evolution and exoplanets to filling in the remaining gaps between raw chemistry and complex biology. With so many Earth species - dolphins, apes, parrots, sea lions - showing borderline abilities to think in sophisticated ways, we are starting to see that word as encompassing a spectrum, not a unique gift. That spectrum may span many other realms, out there…
