A Slice Through an Artificial Universe
Explanation:
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.
