Creative and destructive, dynamic and dazzling, collisions have resulted in many things we take for granted -- the glowing Moon, the Sun's warmth and light, our changing seasons, waves washing up on a sandy shore. They've ended the age of the dinosaurs and changed the very map of the cosmos, reforming galaxies and giving birth to new stars and new worlds.
