No.2 It is not so boring to learn astronomy
A lot of people think that astronomy is full of boring numbers and theories, but if you can compare the astronomy with the views you meet during you are travelling, you may find the astronomy is close to your small world.
For example, when you get into a city, you can imagine that this city is a type of cosmos system, like our Milky Way system. A building is a cosmos unit, and a lot of buildings and roads make up a cosmos system. In the center of the city, like Milky Way, people are crowded, and the buildings are thick. It is as same as the center of the Milky Way. In the center of our galaxy, the stars are crowded also. Do you think they are similar to each other?
