Explanation:
What did our
universe look like when it was young? To answer this, cosmologists run
sophisticated
computer programs tracking the locations of
millions of particles. The
above
animated frame is the result of such a
calculation and shows how our
universe
might have looked when it was just a fracton of its current
age.
The universe started out very smooth - matter
and light are spread almost uniformly. As time progressed,
gravity
caused slight gatherings of mass to accrete so that ever greater
conglomerations formed.
Galaxies and long
filaments
formed - which are shown by the bright patches and streaks in the
above
frame. An
IMAX movie including hundreds of these frames was nominated for
an academy award.
