New research suggests that the presence of oceans, continents, and plate tectonics on Earth may be the reason for the lack of evidence of advanced extraterrestrial civilizations. Geoscientists from the University of Texas at Dallas and the Swiss Federal Institute of Technology propose a change to the Drake Equation, emphasizing the importance of plate tectonics in the emergence of intelligent life.
