Stability and the Gauge Problem in Non-Perturbative Cosmology
Anna Ijjas, Frans Pretorius, Paul J. Steinhardt
In this paper, we describe the first steps towards fully non-perturbative cosmology. We explain why the conventional methods used by cosmologists based on the ADM formulation are g…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
Bouncing Cosmology made simple
Anna Ijjas, Paul J. Steinhardt
We introduce the "wedge diagram," an intuitive way to illustrate how cosmological models with a classical (non-singular) bounce generically resolve fundamental problems in cosmolog…
