Blue skies research

Blue sky research is a kind of scientific research that's based on thinking outside the box and coming up with new and unusual ideas. It's not focused on practical applications, but on understanding the world better. It's called "blue skies" research because the sky is often a blue color and that can symbolize openness and possibilities. Blue sky research is important for exploring possibilities for new technologies and for deepening our knowledge about the world around us.
