The Effective Field Theory of nonsingular cosmology
(21 pages)
|
An Effective Field Theory of a nonsingular bouncing cosmology is considered. The gradient instability responsible for no-go theorems forbidding a stable bounce is removed by including higher order curvature terms.
|
The resulting EFT describes a healthy, nonsingular bounce within it's regime of validity, and is capable of producing a spectrum consistent with observation.
