We present a brief overview of attempts to construct de Sitter vacua in string theory and explain how the results of this 20-year endeavor could point to the fact that string theory harbors no de Sitter vacua at all. Making such a statement is often considered controversial and "bad news for string theory". We discuss how perhaps the opposite can be true.

De Sitter vs Quintessence in String Theory
De Sitter solutions have been recently conjectured to be incompatible with quantum gravity. In this paper we critically assess the progress and challenges of different mechanisms to obtain de SitterExpand
A Comment on Effective Field Theories of Flux Vacua
We discuss some basic aspects of effective field theory applied to supergravity theories which arise in the low-energy limit of string theory. Our discussion is particularly relevant to the effectiveExpand
de Sitter extrema and the swampland
Recently it has been conjectured that string theory does not allow for dS vacua or dS extrema. To scrutinize such a conjecture, it is important to study concrete string theory compactifications andExpand
No classical (anti-)de Sitter solutions with O8-planes
Abstract It was recently proposed that type IIA string theory may allow classical de Sitter solutions with O8-planes as the only localized sources. We show that such solutions are incompatible withExpand
On stringy de Sitter spacetimes
We reexamine a family of models with a 3+1-dimensional de Sitter spacetime obtained in the standard tree-level low-energy limit of string theory with a non-trivial anisotropic axion-dilatonExpand
Open Problems on Classical de Sitter Solutions
Classical 10d string backgrounds with a 4d de Sitter space-time, D-brane and orientifold sources, are commonly believed to satisfy the following: 1. There is no classical de Sitter solution withExpand
Stringy Bubbles Solve de Sitter Troubles
Finding four-dimensional de Sitter spacetime solutions in string theory has been a vexing quest ever since the discovery of the accelerating expansion of the universe. Building on a recent analysisExpand
A Note on the dS Swampland Conjecture, Non‐BPS Branes and K‐Theory
We point out that the de Sitter swampland conjecture would be falsified if classical fluxed Type IIA orientifold vacua with a single non-BPS D7-brane were indeed part of the string theory landscape.Expand

In the first part of this talk, a short overview of the ongoing debate on the existence of de Sitter vacua in string theory is presented. In the second part, the moduli stabilisation and inflationExpand
de Sitter vacua in the string landscape
The late-time behavior of our universe is one of accelerated expansion, or that of a de Sitter space, and therefore motivates us to look for time-dependent backgrounds. Finding such backgrounds inExpand

Constraining de Sitter Space in String Theory.
TLDR
It is argued that the heterotic string does not have classical vacua corresponding to de Sitter space-times of dimension four or higher, and suggests that the genericity arguments used in string landscape discussions should be viewed with caution. Expand
A global view on the search for de Sitter vacua in (Type IIA) string theory
A bstractThe search for classically stable Type IIA de Sitter vacua typically starts with an ansatz that gives Anti-de Sitter supersymmetric vacua and then raises the cosmological constant byExpand
Brane/antibrane dynamics and KKLT stability
String theory has few or no stable nonsupersymmetric or de Sitter vacua, only metastable ones. Antibranes are a simple source of supersymmetry breaking, as in the KKLT model, but various argumentsExpand
