Query: Cosmological significance of one-loop effective gravity   We study the one-loop effective action for gravity in a cosmological setup to
determine possible cosmological effects of quantum corrections to Einstein
theory. By considering the effect of the universal non-local terms in a toy
model, we show that they can play an important role in the very early universe.
We find that during inflation, the non-local terms are significant, leading to
deviations from the standard inflationary expansion.
