How humanity came from believing Creation Myths to postulating the Inflationary Big Bang Theory. The key stages in our understanding of our place in the cosmos and the people who broadened our understanding.
In astronomy distances and times are confusing because of the large numbers of zeros in the figures. This is an easy-to-understand scaling of the Universe in both space and time. Distances in space are represented by the time light takes to travel there. The chronology of the Universe is compared to a real year.
