A Slice Through an Artificial Universe.

We live in the era of humanity when most of our Universe is being mapped . To help understand these maps , astronomers computationally estimate the appearance of several possible candidate universes, to which maps of the real Universe can be compared. Pictured above is a slice through one of these artificial universes, displayed so that each part of the universe is seen at the same time after the Big Bang . The above map corresponds to an area nearly ten billion light years across. Highlighted in red are filaments that each contain thousands of galaxies , while darker regions are nearly de void of galaxies. Our good-sized Milky Way Galaxy would hardly be visible on this map.
