If you think the old line, "Hey, baby, what's your sign?" was about astronomy, you might want to skip this section (that was ASTROLOGY - duh!). Hey, we know - the words DO sound alike, and any word with -logy at the end is just HARD, right?
But if you know a black hole isn't just the space between a lot of people's ears, you'll like these quizzes. If you can tell us what a black hole actually is, you'll LOVE them!
