Eternal Inflation and the Hermeneutics of the Infinite: Interpreting Cosmology at the Edge of Meaning

Философия и космология
The theory of eternal inflation — according to which our observable universe is just one bubble within an endlessly self-replicating multiverse — presents not only a physical but also a hermeneutic challenge.

Novel Possibility of Nonstandard Statistics in the Inflationary Spectrum of Primordial Inhomogeneities

Symmetry, Integrability and Geometry: Methods and Applications, 2012
Inflation is considered one of the cornerstones of modern cosmology. However, the account of the origin of cosmic structure, as provided by the standard inflationary paradigm, is not fully satisfactory. The fundamental issue is the inability of the usual

A step in flux to suppress axion isocurvature

Journal of High Energy Physics
The QCD axion in the pre-inflation scenario faces a stringent isocurvature constraint, which requires a relatively low Hubble scale during inflation. If the axion was heavier than the Hubble scale during inflation, its isocurvature is suppressed and the ...
