What's Bigger than a Galaxy?
A typical distribution of matter (light and dark) in a 100-megaparsec
cube of the universe. Scaled into this map, the Galaxy
Crystal would be less than 1 millimeter wide.
The cosmological model for this piece is tuned to match the Sloan
Survey, an investigation of all galaxies we can see in one quadrant of
the sky. It takes us out to within 1000 megaparsecs of Earth.
The survey isn't finished yet, so you are looking at current
research. Both bright and dark matter are shown, but dark energy
hasn't (yet) entered the picture.
This crystal is 2 1/2" square by 3 1/4" tall.
