Description
The hot big-bang model has changed a lot since its
formulation due to both a better theoretical understanding
and an increasing quantity of observational data. In this
lecture, the hot big-bang model will be described. Its
successes will be detailed as well as its problems. One of
the most important evolutions lies in the understanding of
the structure formation. In particular, the origin of the
density perturbation during inflation and their imprint of
the cosmic microwave background will be explained. Among the
recent developments, the acceleration of the universe is one
of the puzzles to be resolved. The origin of these problems
and various models to solve it will be presented. We will
finish by some highlights on various links between cosmology
and high energy physics (such as topological defects, dark
matter and others).
