摘要

这篇简短的综述，旨在为高能和天体物理学的研究人员，探讨弦理论和沼泽计划的最新理论进展的含义，以理解量子引力中允许的正势结构的界限。这既关系到早期宇宙的暴胀模型，也关系到我们宇宙的命运。本文综述了dS猜想和TransPlanckian Censorship猜想及其与物种尺度的关系。我们为这些原则提供证据，以及它们可能导致的现象学预测。

On the origin and fate of our universe

This brief review, intended for high energy and astrophysics researchers, explores the implications of recent theoretical advances in string theory and the Swampland program for understanding bounds on the structure of positive potentials allowed in quantum gravity. This has a bearing on both inflationary models for the early universe as well as the fate of our universe. The paper includes a review of the dS conjecture as well as the TransPlanckian Censorship Conjecture and its relation to the species scale. We provide evidence for these principles as well as what they may lead to in terms of phenomenological predictions.

期刊介绍： General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
