No, they try their best to stay away from anything too difficult for the average dub to understand. Instead they focus on very simple middle school subjects like how ice freezes(wtf) and fractal patterns in a snowflake(granted that part is in the special features section).
At one point they use the standard creationist approach of "lets show a bunch of 'amazing' statistics to persuade the audience into beleiving in God". For example, they said early on in the video that there are so many stars that if you put a single star on each page of a book it would take you your whole life to flip through all of the pages.
