1. History of the Universe
How did the universe evolve so uniformly?
Why is the CMBR temperature the same everywhere ?
When and how did matter form ?
Why are the H and He abundances the same everywhere (except for He produced in stars) ?
Why is the expansion accelerating?
Is the universe open or closed ?

2. Fluctuations and Large-Scale Structure
Disturbances
in the early
universe
grow in time;
their size
determines large-scale
structure and
properties such as the curvature of
the universe.

3. “Hot spots” in the early universe as we see them today:
Indicators of the curvature of the Universe

4. Uniformity and Isotropy of CMBR
Why is the temperature of CMBR the same everywhere?
The extremely uniform background radiation everywhere in the Universe presents a problem since different parts of the Universe may have been out of touch (even by light) from each other, i.e. outside each other’s event horizons
