WATCH THE UNIVERSE EVOLVE... What you see is a computer simulation depicting the evolution of our entire universe... At the top is a slice of the universe soon after the Big Bang - over 13 billion years ago. As time progresses towards below, the initially smooth universe can be seen becoming more and more clumpy ( stars, galaxies, clumps of galaxies, superclumps, megaclumps, and... sheer emptyness... ). The vertex near down below marks the 21st century AD.

This artificial universe, called a Hubble Volume, was designed to mimic what humanity might see were we to have powerful enough telescopes. Nevertheless, by comparing different computer simulations to reality, we WILL be able to at least better tell what kind of universe we live in. Peace, J.
