Abstract
Nonperturbative quantum gravitational effects can act as a damping mechanism in primordial inflation. It is shown that this effect can reduce the value of to an acceptable value of ∼ in primordial inflation. The same effect reduces the gravitational-wave background by a factor , making the primordial inflation viable.
