Timelines

So an interesting thought is that there are an infinite amount of universes. All nearly identical, except that in each one there is a single difference from another. Basically every time someone makes a choice, soda or juice, a new universe comes to existence. One where you had soda, the other where you had juice. So ideally if I could find the universe where I made all the perfect decisions. Then I simply swap places and live in an awesome life. If only, right? Anyways I think that being complete with this term at school it is only appropriate to start looking at another video series, this one about the great man of science, Carl Sagan.
