Actually, both of those things are what I fear in this world. They are fascinating, yet too vast, mysterious, and frightening. However, if I have to choose, I will choose A. Space! I remember writing an article about black holes when I was still in junior high school! I am also interested in celestial objects such as stars, planets, galaxies, and so on. How beautiful God's creation is! (Although it's quite scary to see how 'big' they are). If the undersea world is just too mysterious, too terrifying... you know, imagining sea monsters! I wouldn't be able to handle it, especially since I can't swim :(
