The big bang and all the rest: The geometry of the universe, the formation of the first light chemical elements, cosmology and quantum gravity
This page features an overview of all our Spotlights dealing with cosmology. In the category Basics, you will find some more information about the big bang models, their predictions and cosmological observations, notably about the cosmic background radiation. Under Cosmology and quantum gravity there are some texts about the cosmological consequences of the current attempts to describe quantum theory and general relativity in a unified setting. Physics in the background features a Spotlight giving background information that is useful for a deeper understanding of the Spotlight texts presented on this page.
The cosmic background radiation
How the spatial geometry of the universe can be derived by observing the cosmic background radiation
The first chemical elements
How the first nuclei of helium, lithium and other light elements were cooked up shortly after the big bang
The physics behind Big Bang Nucleosynthesis, the period shortly after the big bang that saw the first production of light elements such as helium and lithium
How to reconstruct the abundances of light elements shortly after the big bang, and thus test some important predictions of the big bang models against observation
Cosmology and quantum gravity
More information about possible cosmological consequences of the attempts to formulate a theory of quantum gravity.
