Two weeks ago Mr. Gianforte an astronomer came to our school to teach us about space. I learned that the universe doesn't go on forever. He said at the end of the universe there was nothing and I still want to know, what is nothing? I also learned that we don't have a real picture of our galaxy (the Milky Way) because we can't get out far enough to get it all because it is so big. I now know that the Sun is as small as a grain of sand compared to some other stars that we've found. He taught us a lot in the short amount of time he got to teach us about space.
