2.1 SingularitiesPhysical and Relativistic Numerical Cosmology1 Introduction

2 Relativistic Cosmology 

The following sections are organized to track the chronological events in the history of our Universe (see figure 1), focusing on five defining moments in our current understanding of the classical picture: 1) the Big Bang singularity and the dynamics of the very early Universe; 2) inflation and its generic nature; 3) the quark-hadron phase transition; 4) Big Bang nucleosynthesis and the freeze-out of the light elements; and 5) the decoupling or post-combination epoch and large scale structure formation. This particular section summarizes some results on the early Universe (the first four subjects) and a few other topics in relativistic cosmology. The fifth item on the late or post-combination epoch is reserved to a separate section § 3 .

The main cosmological epochs discussed in this review are the Big Bang singularity at t =0, inflation at tex2html_wrap_inline770 secs, the quark-hadron phase transition at tex2html_wrap_inline772 secs, Big Bang nucleosynthesis at tex2html_wrap_inline774 secs, and the post-combination Universe where matter decouples from radiation at tex2html_wrap_inline776 years and structures such as galaxies and clusters begin to form at tex2html_wrap_inline778 years.
