NBIA and Discovery Colloquium by J. Richard Bond

Probing the Cosmic Information in Early and Late Universe Physics

J. Richard Bond
(Canadian Institute for Theoretical Astrophysics)

The Universe is fundamentally quantum and statistical,
a many-paths/many-worlds random-field story that pervades all
discussions in cosmic theory. This talk uses “Cosmic Information
Theory and Analysis” as a unifying theme to explore our ideas of how
the Universe morphed from a smooth Hubble-patch within a vast and
wild probability landscape into the intricate evolving complexity of the
cosmic web we observe. I will discuss the information content of cosmic
parameter measurements, with applications to acceleration trajectories of
late-inflation Dark Energy and of the early-inflaton.

I will also talk about how we try to probe the two great entropy generation
epochs. The first epoch, from which almost all of the entropy of the
universe is thought to arise, is from post-inflation preheating through the
“shock-in-times” of highly non-equilibrium interacting fields. The second
epoch, from which most of the entropy in electrons and baryons arises, is
from crashing density waves as nonlinearities in the cosmic web grow
hierarchically, through the more conventional shocks (in-space).
