I don't mean to be rude but this quiz is wrong. Some questions are great but the answers of some are wrong.

Some of your questions ( such as how long does it take light to reach us) are not clear, the "correct" answer to the question about being able to see a black hole with a telescope isn't right, because you cannot see a black hole by itself, you just see the matter circling around it, and the question about what the universe is made mostly of is wrong, as Dark Energy makes up 68% of the universe while Dark matter only makes up 27%. Just letting you know! :)
