Astrophysicist Warns: Aliens May Be Boring or Unreachable

Researchers are taking the emissions from the vicinity of exoplanet Proxima B seriously. But if it is truly a technological signal, what would follow?

Boring? How very un-Star Trek of them! But it’s possible, says Caleb A. Scharf, director of astrobiology at Columbia University (pictured). He worries that, “Perhaps other life in the universe is, in the end, utterly dull.” Why might he think so? He is reflecting on the recent report of what may be a technological signal at roughly 982.002 MHz, coinciding with the direction of Proxima Centauri. If it is, what might the aliens turn out to be like? There’ll be some initial oddities, some curiosities that aren’t quite the things we planned for. A dull carrier wave signal for instance. Over time more evidence will show up, until eventually it’s clear that there are lots of species out there, puttering…

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…
