Planetarium Show: Imagining the Size of the Universe

How big is the universe? How can we seek to answer this question or understand the answer once we have it? Our universe is much bigger than we imagine it to be but, using analogies and visualizations, we can start to grasp its true dimensions. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.
