* Peaks: For fixed
,
the "spectrum''
c1 is expected to have peaks, whose
position, height and shape give us information on physical parameters (baryon
density,
Hubble constant, topological defects vs inflation, etc); The position of the
first peak indicates that the universe is spatially flat.
* Preferred directions?
2007, An alignment ("axis of evil") has been reported between the
quadrupole and octopole moments in the WMAP microwave sky survey, but its significance
is still being
debated.

Sachs-Wolfe Effect
* Idea:
A contribution from changes in the
's
4-momentum due to density perturbations; Allows us to correlate features in
the
cmb to large-scale structure.
