The Weak Gravity Conjecture
Isabel Koltermann (JGU Mainz)

The Weak Gravity Conjecture (WGC) very basically states that “gravity is the weakest force”, which gives rise to many further implications. It is considered as being maybe the most important criterion to distinguish consistent theories of quantum gravity, the “landscape”, from the so-called “swampland”, i.e. the space of consistent low-energy effective field theories which cannot be completed into gravitational theories, and the evidence in favor of the WGK and its consistency steadily grows. The conjecture addresses phenomenological questions as well as deep general questions regarding the nature of quantum gravity and has appeared in different ways in recent papers.
