Q:
Where on the web can I find a picture of the structure of the
universe? The universe as currently mapped shows a fibrous
structure, with large voids of about 150 million light years
across. This picture, I presume, comes from light that started
traveling from these galaxies several million years ago. Does
this mean this picture was formed before the galaxies (or
clusters of them) had a chance to travel much relative to each
other?
A:
For a good image of the large scale structure of the universe
try NASA's Astrophysics
Data Base and searching the reference below.
