Abstract :
The Cosmic
Microwave Background (CMB), the fossil light of the Big Bang, is the oldest
light that one
can ever hope to observe in our Universe. The CMB provides us with a
direct image of
the Universe when it was still an "infant" - 380,000 years old - and
has
enabled us to
obtain a wealth of cosmological information, such as the composition, age,
geometry, and
history of the Universe. Yet, can we go further and learn about the primordial
universe, when it
was much younger than 380,000 years old, perhaps as young as a tiny
fraction of a
second? If so, this gives us a hope to test cosmic inflation, the leading
paradigm
on the origin of
our Universe at ultra high energies. In my
talk I will review the physics of
temperature and
polarization anisotropies of the CMB and the key results from the recent
experiments, and
discuss future prospects on our quest to probe the physical conditions
of the very early
Universe.
