# The Swampland: Introduction and Review

## TL;DR

This paper introduces and reviews the Swampland program, which seeks to identify effective theories compatible with quantum gravity, covering key conjectures and ideas in the field.

## Contribution

It provides a comprehensive overview of the Swampland program, summarizing key conjectures and concepts for the first time.

## Key findings

- Summarizes the Weak Gravity Conjecture
- Reviews string theory compactifications
- Discusses the de Sitter conjecture

## Abstract

The Swampland program aims to distinguish effective theories which can be completed into quantum gravity in the ultraviolet from those which cannot. This article forms an introduction to the field, assuming only a knowledge of quantum field theory and general relativity. It also forms a comprehensive review, covering the range of ideas that are part of the field, from the Weak Gravity Conjecture, through compactifications of String Theory, to the de Sitter conjecture.
