Consider the Milky Way...

The human mind is not capable of contemplating the vastness of a universe, so this video encourages the viewer to contemplate instead a rather tiny, cosmically insignificant galaxy - our Milky Way.  It is, after all, the only thing we can see in our night sky (except for the Andromeda galaxy).  This presentation is an attempt to give us a perspective on its size.
