You still have quite a bit to learn about the way our universe works. But not to worry, there is so much to learn no one knows it all! The most important thing is to keep being curious and be willing to learn more.
Nicely Done!
You didn't answer all questions correctly but you can certainly hold your own when it comes to discussing this universe of ours. You have some more to learn, but don't we all? You certainly have a scientific curiosity.
Superb Knowledge!
You know so much about physics, you could easily teach it! In fact, we hope you are. You stand on the knowledge of giants. Like them, you like to know and understand the world around you. This is a great attitude to life!
