This seems to offer an interesting (partial) candidate for the Great Filter. What if there are tons of advanced civilizations on tidally locked planets orbiting red dwarfs, who have never reached for the stars, because they simply can’t see them?
Or rather, they can see them only once they’ve developed the technology to explore a side of the planet which they’re extremely poorly adapted for. Imagine if we had only been able to even begin to study astronomy through polar expeditions, for example.
