Knowing how to use a scale on a map helps me understand distances in the universe because of the large objects and distances. They similar because it is the same objects just in a model and the same amount of the object if you were comparing sizes scaled down. They are much different because of the distances and sizes of the objects. None of the objects in space could fit on earth or anywhere near it. What is happening is that the speed of light is extremely fast and light years travel a long way. We see the light of the star only because it produced the light a long while ago, more precisely, we are seeing the light 16 years and 219 days later. One light year is 6 trillion miles so 16.6 multiplied by that 6 trillion is about 99.6 trillion miles away. Scientist will most likely never travel that mar in space, there is just not enough, technology, research, or supply. It is not critical to be so accurate with the numbers because the spaces and numbers are so big, up to the trillions, that it is impossible to visualize on earth. Scales make the large distances easier to comprehend, especially when measure in feet.
 * 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?**
 * 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?**
 * 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?**
