Early-Universe Cosmology

In General > s.a. astronomy; inflation; kaluza-klein theory; observational cosmology; standard cosmological model.
* Goals: Explain the matter/antimatter asymmetry and the growth of inhomogeneities to become galaxies (by models for the formation of these inhomogeneities and proposals for dark matter).
* Features: The main paradigm that has emerged is that of inflationary universe (uses guts, symmetry breaking, etc).
* Classical modifications: They include oscillating universes and bounces.

Quantum Gravity, the Transplanckian Issue and Pre-Big Bang > s.a. brane world; quantum cosmology; string phenomenology.
* Transplanckian challenge: The issue appears when we trace fluctuations with presently physical wavelengths backwards in time until they cross the Planck scale, the limit of validity of conventional quantum field theory; One concludes that unknown ultraviolet physics left an imprint in the observable cosmological fluctuations. This issue is usually addressed within the inflationary context, but it is much broader.
* Ekpyrotic cosmology: Based on brane world cosmology as pre-big bang scenario.

Particle Production > s.a. astrophysics; graviton; relativistic cosmologies.
* Inflation: Based on a cosmological phase transition as pre-standard model scenario.

Other Stages > s.a. baryogenesis [and leptogenesis]; nucleosynthesis
* Decoupling: The period when the Universe was dark, stars had not yet formed, and the cosmic microwave background no longer traced the distribution of matter, in which the primordial soup evolved into the rich zoo of objects we now see.
