Description
The Universe is fundamentally quantum and statistical, a many-paths/many-worlds information-theoretic random-field story that now pervades all discussions in cosmic theory. This lecture uses Cosmic Information Theory and Analysis (CITA) as a unifying theme to explore our ideas of how the Universe morphed from a smooth Hubble-patch within a vast and wild landscape into the ephemeral cosmic web we observe, with focus on early inflation, including preheating, and late inflation (aka Dark Energy). Particular topics will include: the confrontation of our nonlinear gastrophysical simulations of entropy generation with Compton scatterin! g observables aka the Sunyaev Zeldovich effect; the acceleration trajectory approach to inflation and current and forecasted constraints on gently-broken and radically-broken scale invariance and on gravity waves; the delivery of almost all of the entropy in the universe through a preheating "shock-in-time"; radical non-Gaussianity of primordial curvature fluctuations and its constraints; physically-motivated parameterizations for Dark Energy equation of state trajectories and their current and forecasted constraints.
