Powers of Ten

You might think that you live on a pretty big planet. Well, as "Powers of Ten" shows, Earth is nearly atom-sized compared to the universe. Starting by showing some picnickers in Chicago, the scene zooms out showing squares, each one ten times larger than the previous one, extending all the way to the outer reaches of the known universe...before reversing and zooming in on the man's hand. This documentary, directed by Charles and Ray Eames, just goes to show how tiny we really are, and that the universe is truly more massive than we can ever truly imagine. This topic is one of the first steps towards understanding physics, but above all, it humbles you. Really good one.
