Take this for example, many thought the world was flat, that theory developed (changed) to the fact that the world is round instead of flat. Current theories that are changing daily-- "How was the universe formed?" "How did life begin"? "Was there ever life on Mars"? "What is all that DNA for?" "How do we make more efficient solar cells?" "What will happen with global warming, and how can we modify it?"
