摘要：

A non-zero cosmological constant allows massless gravitons to self-interact via a coupling of dimension three. If the cosmological constant is positive then the background geometry will subject gravitons to an enormous redshift. These two facts are together responsible for the severe infrared divergences which detailed, explicit calculations [N.C. Tsamis and R.P. Woodard, Strong infrared effects in quantum gravity, preprint CRETE-92-17, UFIFT-92-24] reveal in loop corrections to the gravitational force law. We argue that, as a result, the cosmological interaction has a finite lifetime. Furthermore, this lifetime is consistent with inflation.
