A question I’ve always had is, assuming we do pick up very strong signatures or signals of life very far out, would it ever make sense (or, is it even possible) to create a ginormous optical telescope in space that could attempt to take pictures at a resolution that would be the next best thing to being there?
How big would it have to be in order to get a Google Earth resolution on a planet many light years away?
