Why was the Search for #Extraterrestrial Intelligence (#SETI) 👽 unsuccessful so far ?

#Life 🦠 appeared pretty much as soon as it could, right when the #oceans formed and our #planet stopped being a molten 🌋 hellscape. That might have been as early as 3.7 billion years ago. But #intelligent life appeared basically yesterday—what we identify as anatomically modern humans arose about 120,000 years ago. https://arstechnica.com/space/2023/05/were-essentially-alone-in-the-universe-and-thats-ok

We’re effectively alone in the Universe, and that’s OK

Solitude is not a curse—it urges us to explore the mysteries of our galaxy and beyond.

#CambridgeUniversity 📆 2022 While our #Anthropocene phase displays key features of a #planetary #intelligence, it appears to lack the critical characteristic of autopoietic self-maintenance. Driving the coupled #Earth 🌏 systems beyond their safe-operating boundaries, early-Anthropocene human 👫 activity is threatening/degrading, rather than maintaining https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/intelligence-as-a-planetary-scale-process/5077C784D7FAC55F96072F7A7772C5E5#sec6

In 📆 1995 the first #exoplanet was discovered orbiting Pegasus 51, 50 light-years 📏 distant from #Earth. Since then, there have been more than 4,000 confirmed discoveries of exoplanets 🪐 in our #galaxy. Almost all #stars 🎇 have #planets, which radically improves 📈 the odds of our discovering #intelligent life in the #universe 🌌 https://www.washingtonpost.com/science/intelligent-life-probably-exists-on-distant-planets--even-if-we-cant-make-contact-astrophysicist-says/2021/06/18/ee6a5316-cd2d-11eb-8cd2-4e95230cfac2_story.html

Despite the odds, the existence of such life-forms in the universe matters deeply to me and many others on Earth.
