 * 1) Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? How are they similar? How are they different?
 * Yes, because it would be easier to measure distances in the universe with a scale if you understand how to use a scale on a map. They are similar because they are both calculating the distances. They are different because their both using different types of measurement and scale.
 * 1) Vast distances in space are often measured in light-years. A light-year is the distance that light travels in one year, or about 6 trillion miles. Altair, a star in the constellation Aquila, is 16.6 light-years away, which means that the light we see now from that star left its surface 16 years and 219 days ago. Describe what was happening in the world when the light we are seeing from Altair first left that star. How far away is Altair in miles?
 * We were looking back 16 years and 219 days back in time and at that time I had a brother who was 11 years old and I wasn't born at that time. Altar is 98.36 trillion miles away from the earth.
 * 1) Explain why it would be impossible for scientists to measure stellar distances that are accurate to within a few feet. Why is it not critical to attain such accuracy when dealing with astronomical distances?


 * It would be impossible because we don't measure in the universe with feet, inches, or miles because they are too small. It is not critical to attain accuracy when dealing with astronomical distances because the stars could be always changing its size.
