TL;DR
This paper derives a general equation for quantum gravitational corrections to cosmological scalar fluctuations and estimates these effects in a de Sitter universe.
Contribution
It introduces a new framework for calculating quantum gravity corrections within a Born-Oppenheimer approach to cosmology.
Findings
Quantum gravitational corrections to scalar fluctuation spectrum are explicitly estimated.
The corrections are characterized for a de Sitter universe.
Provides a foundational equation for further quantum gravity cosmology studies.
Abstract
A general equation, describing the lowest order corrections coming from quantum gravitational effects to the spectrum of cosmological scalar fluctuations is obtained. These corrections are explicitly estimated for the case of a de Sitter evolution.
