de Sitter Space is Unstable in Quantum Gravity
arXiv:1608.07237 · doi:10.1103/PhysRevD.94.125025
Abstract
Graviton loop corrections to observables in de Sitter space often lead to infrared divergences. We show that these infrared divergences are resolved by the spontaneous breaking of de Sitter invariance.
