        Mysteries of Deep Space | Time Travel to the Edge of the Universe and Back!

        In this lesson, students will study the size of the universe, calculate the time to travel to destinations, and construct a time scale model of the universe by using time travel distances. When we observe the night sky, the planets, stars and galaxies appear to be close together. We know that some objects are closer to the Earth than others and that enormous distances separate us from other objects in the universe. As we gather information from the farthest reaches of the universe, we can learn about the history of the universe.
