**Everything You Always Wanted To Know About The Cosmological Constant Problem**

by Jerome Martin

**Publisher**: arXiv 2012**Number of pages**: 89

**Description**:

This article aims at discussing the cosmological constant problem at a pedagogical but fully technical level. We review how the vacuum energy can be regularized in flat and curved space-time and how it can be understood in terms of Feynman bubble diagrams.

**arXiv**

Ekpyrotic and cyclic cosmologies provide theories of the very early and of the very late universe. In these models, the big bang is described as a collision of branes - and thus the big bang is not the beginning of time.
