Hi, I know the title isn't really going to explain much, but I hope I can get you to understand my problem. My book is a sci-fi book (actually the same one that I came onto the forums almost a year ago to ask about, how long is it going to take me to start it?) with action set in both outer space and on planets. What I want to know is, how could I get the right balance so that both worlds seem huge? I don't want the characters to just go, say, "He's on Earth." "Ok." As if just knowing something's on Earth tells them exactly where it is. Does anyone have any advice on this?
