TL;DR
This essay explores the potential significance of the pre-inflationary phase in cosmology and the possible role of Quantum Gravity before inflation began, addressing foundational questions in early universe physics.
Contribution
It investigates the theoretical and phenomenological implications of the universe's state prior to inflation and the influence of Quantum Gravity in this context.
Findings
Pre-inflationary phase may have observable effects
Quantum Gravity could influence early universe dynamics
Provides new perspectives on initial conditions for inflation
Abstract
While inflation has been an extremely successful cosmological paradigm, almost certainly something have had to have happened before it began. Can the pre-inflationary phase be of any theoretical or phenomenological significance? Could Quantum Gravity have played any interesting role in this story? These are some of the questions we want to explore in this essay written for the Gravity Research Foundation 2013 "Awards for Essays on Gravitation" competition.
