The Universe Evolves
Explanation:
Scroll right and watch the universe evolve.
Above is a computer simulation depicting the
evolution of our entire universe.
On the far left is a
slice of the universe
soon after the
Big Bang - over 10 billion years ago.
As time progresses toward the right,
the initially smooth
universe can be seen becoming more and
more clumpy. The vertex near the far right marks the present day.
The largest slice of the universe actually surveyed is
simulated to the vertex's right.
This artificial universe, called a
Hubble Volume, was designed to mimic what
humanity might see were we to have powerful enough telescopes.
By comparing different computer simulations to
reality, we might be able to better tell what kind of
universe we live in.
