		What would it be like to fly through the universe?
Possibly the best simulated video of this yet has been composed from 
recently-released galaxy data from the 
Sloan Digital Sky Survey.
Every spot in the 
above video is a galaxy containing billions of stars.
Many galaxies are part of 
huge clusters, 
long filaments, or 
small groups, while 
expansive voids 
nearly absent of galaxies also exist.
The movie starts by flying right through a large nearby cluster of galaxies 
and later circles the SDSS-captured universe at about 2 billion light years 
(a redshift of about 0.15) from Earth.
Analyses of 
galaxy positions and movements continues to bolster the case that 
our universe contains not only the bright matter seen, like galaxies, but also a significant amount of unseen 
dark matter and 
dark energy.
