Cosmology almost always lacks context.
Cosmology books, papers and articles typically provide a historical account and often elaborate mathematical explanations, but rarely present a physical grounding framework to explain how it fits in with firmly established physics.
My concerns about this led to an invitation to give a talk for a Cosmology Conference sited in the magnificent Olympic Peninsula entitled “Ground Rules for Cosmological Physics.” That talk resulted in an invitation to provide a paper based upon it.
This paper “Ground Rules for Cosmological Physics” is simply a reminder for cosmology enthusiasts of the bright line separating the laws of physics from science fiction. To help examine cosmology science claims and concepts it provides some tools: rules, guidelines and a definition of space.
It explains the stringent thresholds for an idea before it can accurately be called a scientific theory or hypothesis; and how theorists nearly always bear the burden of proof for their ideas.
“These simple tools provide solid ground so you may more easily examine cosmology claims to help make up your own mind which side of the science / science fiction line a specific claim belongs on.”
