Explores the expansion and Hubble law in astrophysics, covering the Hubble constant, cosmological redshift, critical density, and cosmic background radiation.
Explores precarious naturalness, addressing hierarchy and cosmological constant issues through new post-naturalness paradigms and selection mechanisms.
Introduces scalar gravity, covering covariant derivatives, Ricci tensor, Einstein Equivalence Principle, and the generalization of Newtonian gravity equations.
Discusses the inflationary theory as a solution to initial condition problems in the universe, covering scalar fields, density perturbations, and basic equations.
