Astronomy animations include an exploration of
the Big Bang idea of how the Universe came into existence, roughly about
13.7 billion years ago. Big Bang theory combines the cosmological principal
with the idea of continuing universal expansion according to the Friedmann-Lemaitre
model of general relativity. Lots of ideas at the moment include the notion
of Dark matter, providing a gravitational pull on the visible matter of
the galaxies which would explain the observed acceleration of the universe’s
continued expansion.
Other (loop quantum gravity) ideas suggest that the Big Bang was the beginning
of a period of expansion that followed after a period of contraction.
The Big Bang was in effect a Big Bounce. The Big Bang theory might be
seen to imply infinite density (all those infinite galaxies, planets,
comets etc had to come from somewhere), which is seen by some as a tricky
concept. The Big Bounce idea gets round this.
Animations also include shots of Cassini exploring Saturn and Titan -
a simply fantastic site at http://saturn.jpl.nasa.gov/home/ covers all
this with shot of Titans surface, Saturn rings, updates on Cassini’s mission,
where Cassini is at the moment etc.
