Motion of the Solar System

The video was kewl, but I'd punch up the sound track.

"It's a great big universe and we're all really puny…"

or

"It's all a dream… light passing by on a screen…
and there's you and I on a beam…
speeding through the universe…"

Animaniacs, or Moody Blues? Hmm.

Srsly, I've seen part 1 before. Part 2 was less informative, but still interesting. Increasingly, we see the universe modeled, and it's increasingly amazing.
