Big DEAL !! So many times greats like Heinlein and Silverberg have written about us going to exoplanets, and it being like Earth. Sorry,,,, NO! from https://www.universetoday.com/167659/plate-tectonics-might-only-occur-on-0-003-of-planets-that-makes-earth-very-special-indeed/ Plate tectonics: Image Credit: NASA/Goddard Space Flight Center Scientific Visualization Studio POSTED ONJULY 2, 2024 BY SCOTT ALAN JOHNSTON Plate Tectonics Might Only Occur on 0.003% of Planets. That Makes Earth Very Special Indeed. Plate tectonics, oceans, and continents might just be the secret ingredients for complex life on Earth. And if these geological features are rare elsewhere in the universe, then perhaps that explains why we haven’t yet discovered intelligent alien life. New research from American and Swiss Earth scientists suggests that these ingredients represent missing variables in the famous Drake equation, devised more than half a century ago to estimate the chances of finding advanced civilizations in our galaxy. Including these new variables could completely rewrite the probability of detecting intelligent life in the Milky Way. Go to the citation for the rest ----.
