The blue areas are the absence of dark mater. Dark matter is what holds the galaxies and super clusters together.
Dark energy is everywhere uniformly. It is a property of space itself. The blue areas are where dark energy is more influential than gravity due to the absence of matter and dark matter.
@cmarcallen: No, the red is regular and dark matter together in galaxies represented by red dots too small to show individually. They collapse towards each other under gravity, leaving the empty voids between them in 13 billuion years of time.
@Mueiwark: You misunderstand the scale of the view. The red are galaxies, way too small to be seen individually, thousands together making a red haze that slowly collapses together under gravity.
@chainsore: z is an inverse measure of time (that is, it gets smaller as simulated time advances), and it is logarithmic, so that near the end it slows down. If it were just linear time, all of the collapse would happen right near the end. After some study, and as itsafarcry says, it is a measurement of redshift.
The line at the bottom shows the size of 50 megaparsecs of length. A parsec is 3.26 light years, so 50 Mpc is about 163 million light years.
this video is amazing

Looks like the neural networking in the brain. I wonder if the blue area represents expanding dark matter/energy?

That's how the gallaxys probably have formed. Awesome.

what is z and whats mpc ????

z is the redshift which means time,it is earlier when z is larger. mpc is distance. million parsecond.about 3,000,000 light year~
