ET Expert Thinks That ET Is Probably AI (Artificial Intelligence)

Given the immense interstellar distances, not being alive might be the only way ET could get here.

Search for Extraterrestrial Intelligence (SETI) astronomer Seth Shostak (pictured) confesses that these are exciting times for alien hunters like himself, what with the Pentagon’s anticipated July 25 report on unidentified aerial phenomena. Still, he doesn’t expect any big revelations: “I think it’s overwhelmingly likely that aliens are present in our galaxy. But I don’t believe they’re hanging out in our airspace. Not now, and not in historic times.” On the other hand, he goes on to say, every third star in our galaxy could host an Earth-like planet so the odds are we are not alone. Few life forms on Earth resemble humans, so why should extraterrestrials? But if we are not alone, what would ET be like? A gaseous…

Astronomer Bets a Cup of Coffee That We’ll Encounter ET by 2036

Seth Shostak points to the increase in the number of exoplanets identified and the increase in computing power

Seth Shostak, iconic astronomer who directs the Search for Extraterrestrial Intelligence (SETI), is so confident that the vast increase in computing power, based on Moore’s Law, will make the difference in detecting signals from alien civilizations that he will bet you a cup of Starbucks coffee that we make contact by 2036. Moore’s Law (1965) originally held that computers would double in power every two years. But today’s pace is actually faster than that. And on the horizon is quantum computing and carbon computing, which would speed things up while reducing energy consumption. So Shostak (pictured) is looking at considerable reinforcements for a systematic search. He stresses that the search for ET is now largely computerized: “We don’t sit in…

Seven Reasons (So Far) Why the Aliens Never Show Up

Some experts think they became AI and some that they were killed by their AI but others say they never existed. Who's most likely right?

Science fiction author Matt Williams is writing a series at Universe Today that offers the leading explanations for why They never write, They never phone… It’s based on an incident in 1950 when Italian physicist Enrico Fermi (1901–1954) asked colleagues at the Los Alamos National Laboratory a question: If space aliens are a sure thing, “Where is everybody?” As Seth Shostak puts it at Search for Extraterrestrial Intelligence (SETI), The remark came while Fermi was discussing with his mealtime mates the possibility that many sophisticated societies populate the Galaxy. They thought it reasonable to assume that we have a lot of cosmic company. But somewhere between one sentence and the next, Fermi’s supple brain realized that if this was true,…
