Mini-Quiz: Characteristics of the Universe

by Ron Kurtus (revised 30 November 2011)

Take this Mini-quiz to check your understanding of the lesson material.

1. Why are light-years used to measure the size of galaxies?

Because the indicate the number of years in the Universe

Other measurements are too small to denote the great distances

Light travels faster than the eye can see

2. Is there any proof that the Big Bang really happened?

There is evidence that it could have happened but no proof

Yes, because telescopes can look into the past to see the explosion

No, but there is proof that it did not happen

3. How can there be other universes?

It is nonsense, because this is the only Universe

Space ships have already been to those universes

They may exist outside the boundaries of our Universe

If you got all three correct, you are on your way to becoming a Champion in Astronomy. If you had problems, you had better look over the material again.
