Answer 1

I can only help you with the last two questions from lesson 5.01

-Because light is the fastest thing in our universe you can calculate the distance by how much time light has to take in order to travel that distance which is light years

-Light years, and every measurement you can think of. Except light years are the easiest most efficient way to measure distances
