SpletWe argue for a relation between the measured value of the dark energy density Λ and the supersymmetry breaking scale. We derive it by combining two quantum gravity consistency swampland constraints, which tie the dark energy density and the gravitino mass, respectively, to the mass scale of a light Kaluza-Klein tower and, therefore, to the UV cut … SpletThe Swampland program aims to determine which low-energy effective field theories are consistent with nonperturbative quantum gravity considerations.

In physics, the term swampland refers to effective low-energy physical theories which are not compatible with quantum gravity. This is in contrast with the so-called "string theory landscape" that are known to be compatible with string theory, which is believed to be a consistent quantum theory of gravity.
