Improving Physical Cosmology: An Empiricist's Assessment
P. J. E. Peebles
TL;DR
This paper evaluates the current $\\Lambda$CDM cosmology, acknowledging its success while exploring less examined avenues that could lead to improved theories of the universe.
Contribution
It provides a curated list of underexplored ideas and potential research directions to refine or replace the standard cosmological model.
Findings
$\\Lambda$CDM passes rigorous tests as a good approximation.
Identifies less explored areas that may offer insights for better theories.
Suggests new research avenues for cosmological improvements.
Abstract
The CDM cosmology passes demanding tests that establish it as a good approximation to reality, but it could be improved. I present a list of possibly interesting and less well explored things that might yield hints to a better theory.
