Scale of the Universe
This lecture gets us into the topic of "Lookback time," and is covered in Chapter 2 in the text.
There will be a graded homework assignment in "Launchpad" that goes with this.
After completing the above lecture, the video below should be more relevant. Note the distances cited on the left-hand side of the screen and how they are expressed in terms of light speed and "look-back time." Most of the images you will see are actual photos with very little CGI, except at the very end.

History
The following topics are also covered in Chapter 2 in the text. If we are to understand our current concept of the Universe, it's essential to know how we got here.
Yeah, history IS important!
