      Explanation: How different does the universe look on very small scales?   
      On very large scales? The most famous short science film of its   
      generation gives breathtaking comparisons. That film, Powers of Ten,   
      originally created in the 1960s, has been officially posted to YouTube   
      and embedded here. From a picnic blanket near Chicago out past the   
      Virgo Cluster of Galaxies, every ten seconds the film zooms out to show   
      a square a factor of ten times larger on each side. The 9-minute video   
      then reverses, zooming back in a factor of ten every two seconds and   
      ends up inside a single proton. The Powers of Ten sequence is actually   
      based on the book Cosmic View by Kees Boeke in 1957, as is a similar   
      but mostly animated film Cosmic Zoom that was also created in the late   
      1960s. The changing perspectives are so enthralling and educational   
      that sections have been recreated using more modern computerized   
      techniques, including the first few minutes of the movie Contact. Ray   
      and husband Charles Eames, the film's creators, were known as quite   
      visionary spirits and even invented their own popular chair.
