A tour through the Universe, introducing many of its inhabitants (stars, galaxies, clusters of galaxies, the tapestry). Get an idea of relative sizes and timescales for objects and processes.

Outlining the global properties of the Universe: Isotropy, homogeneity,
expansion, Hubble law. How we access cosmic history. The cosmic age.
Helium synthesis. The five cosmic components. Expansion history.
(3) The First Million Years
A fairly detailed summary of the properties of the Universe during its
first million years. Topics include the Universe's density, temperature,
pressure, radiation field, fogginess; and how all these things change
with time. The ocurrence of sound waves, and how these are generated.
(4) The Growth of Structure
How the first stars are born from gravitationally amplified sound waves.
The succession of ever increasing structures: Stars, to galaxies, to clusters,
to the tapestry. Each formation illustrated with movies.
