Each assignment is expected to be made up of your own words. Never lose sight of the fact that your purpose is to convey information and your ideas about that information. The Universe includes all the planets, stars, and material between them. Man's ability to study this vast system has improved rapidly with machines like the Hubble telescope and probes sent to other planets. There are many theories about the universe based on these indirect observations.
Astronomy is the science most directly related to studying the universe.
Much of astronomy is based in physics, but astronomers must be experienced in geology and chemistry as well. The Encyclopedia Britannica and these pages of astronomy links and geology links will be helpful in your research for the next two assignments. One theory about the beginning of the Universe is called the Big Bang Theory . Write two paragraphs, one detailing how this theory explains the beginning of the Universe, the other detailing how this theory predicts the Universe will end.
