Can somebody please confirm that my answers are right?
1. At what time on Earth did the light start from a galaxy 2 billion light years away?
My answer was 2 X 10^9 years. This problem seemed too easy to be true.
2. How far is the nearest star in kilometers (about 1.3 par sec away)?
My answer: 3.77 X 10^12 km
Thanks for the help!
