Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding what happened in the earliest times after the Big Bang, and reconciling observations with the basic theory.
Meget af det aktuelle arbejde i kosmologien drejer sig om at forstå, hvordan galakser dannes inden for rammerne af Big Bang, om at forstå, hvad der skete ved Big Bang, og om at forene alle observationer med den basale teori.
