This is a fascinating video! It really makes me realize how small we really are.
The video's description:
The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.
Though I think the background music is fine, I think Pink Floyd's Shine On You Crazy Diamond would fit better.
Try it yourself: Start both videos at the same time. Then turn down the volume of the top video and turn up the volume of the bottom one. Then only watch the top video.
