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, per-
haps as young as a tiny fraction of a second? If so, this gives us
a hope to test competing theories about the origin of the Uni-
verse at ultra high energies. In this talk I review the present status
and future prospects on our quest to probe the physical condition of
the very early Universe. |
