Covers the relationship between primordial curvature perturbations and inflationary magnetic fields, emphasizing observational evidence and theoretical models.
Explores precarious naturalness, addressing hierarchy and cosmological constant issues through new post-naturalness paradigms and selection mechanisms.
Explores the naturalness problem in UV completions of the Standard Model and proposes a mechanism related to the Higgs mass determining the universe's expansion.
Explores the importance of the perfect fluid in cosmology and its coupling to gravity, leading to a discussion on the Einstein universe and static gravity.
