弱引力猜想认为，在量子引力理论中，对于某些粒子，任何规范力都必须中介比重力更强的相互作用。这一说法与物理和数学的许多不同领域有着惊人的深度和广泛的联系。已经提出了对基本猜想的几种变体，包括更强有力的声明，但仍然被所有已知的一致量子引力理论所满足。我们回顾了这些相关的猜想，以及它们在弦理论中的有效性的证据。我们还回顾了关于这些猜想的各种论点，这些论点往往分为两类：根据一般原理认为猜想是可信的定性论点，以及针对各种特殊情况或猜想的类似的定量论点。我们还概述了这些猜想对粒子物理学、宇宙学、广义相对论和数学的影响。最后，我们指出了未来研究的重要方向。
The Weak Gravity Conjecture holds that in a theory of quantum gravity, any gauge force must mediate interactions stronger than gravity for some particles. This statement has surprisingly deep and extensive connections to many different areas of physics and mathematics. Several variations on the basic conjecture have been proposed, including statements that are much stronger but are nonetheless satisfied by all known consistent quantum gravity theories. We review these related conjectures and the evidence for their validity in the string theory landscape. We also review a variety of arguments for these conjectures, which tend to fall into two categories: qualitative arguments which claim the conjecture is plausible based on general principles, and quantitative arguments for various special cases or analogues of the conjecture. We also outline the implications of these conjectures for particle physics, cosmology, general relativity, and mathematics. Finally, we highlight important directions for future research.
