The diameter of the observable universe is known to be about 46 billion light years. That's big! Not only is 46 billion a big number but even one light year, the distance a beam of light travels in one year, is a very long distance. How far is it? In this seminar, we will investigate the size of things starting with familiar objects having sizes we can readily grasp and carefully working our way up to the largest most distant objects in the observable universe. We will describe how these sizes and distances were first measured by scientists/philosophers as our understanding of the universe we live in evolved and matured over the years.
