New Study on Why Aliens Never Phone, Never Write, Never Visit

Planetary scientists suggest that civilizations follow a trajectory in which there is only a short window of time to look for intelligent extraterrestrial civilizations

On the one hand, the National Academy of Sciences has said that we may communicate with extraterrestrial intelligences during our lifetimes. On the other hand, Italian physicist Enrico Fermi (1901–1954) asked, “Where are they?” (the Fermi Paradox). A new study suggests that the natural development of civilizations may be to blame: In the hopes of answering this question, a new paper published on May 4 in the journal Royal Society Open Science claims that “civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.” “Either outcome — homeostatic awakening or civilization collapse — would be consistent with the observed absence of [galactic-wide] civilizations.”…

The Drake Equation at 60 Years: The Second Most Famous Equation

After Einstein's e = mc squared. New technology is improving our ability to search the skies for signs of possible extraterrestrial civilizations

Last year marked the sixtieth year of the iconic Drake Equation, developed by astronomer Frank Drake aimed at stimulating the public to think about the prerequisites for life on other planets. Seth Shostak at Search for Extraterrestrial Intelligence (SETI) says it is the most famous equation after e = mc2 and offers a bit of its history: The Drake Equation was cooked up by astronomer Frank Drake in 1961 to serve as the agenda for the first meeting on the topic of SETI. In 1960, Drake had conducted a pioneering search for extraterrestrial signals – a several-week long effort he named Project Ozma. Somewhat unexpectedly, this modest experiment attracted a great deal of attention, and Drake was encouraged by J.P.T.…
