Posted on 08/13/2012 2:33:41 PM PDT by SunkenCiv
Explanation: 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.

February 1968 alternate take of the song, appeared on Anthology 2 in 1996.
What would have been real cool if in the video we got real close to one of the galaxies and skimmed over it for a while.
How fast are we going? Like warp factor 12?
Simply wonderful - thanks for posting.
‘Course, only on earth did intelligent life ever develop . . .
I think they missed a couple. Then again, my screen may not have been big enough to hold them all.
[ geek alert! geek alert! ] The warp factor in Star Trek is speed of light times the square of the number; one of the little tidbits one notices is, for example, in Star Trek IV: The Voyage Home, Sulu starts counting at “warp 2” — warp 1 is exactly the velocity of light, and the end-run around the Einstein limit is that warp 1 is off-limits. Sooooo, warp 12 would be 144 times c; also in ST4:TVH, timewarp is accomplished by a warp 10 (100 times c) slingshot trajectory around the Sun, an arbitrary figure required by the needs of scifi. :’)
Looks as if the TV shows got the view from a starship all wrong.
That’s a wonderful video! The way it will truly look when we have warp drive. ;-P
