What is Physical Cosmology?

Is a "physical cosmology" an equivalent term for "reality", or "universe". If I were to say one could "rewrite cosmology in any way they wish, even if logically impossible", would that be an equivalent statement as saying one has omnipotent control over energy/matter, spacetime, and the physical laws and constants?

Odd question yes.

Cosmology is "the study of the universe" not "the universe".

couldn't it mean like a cosmological model, or a religious cosmology, both of which mean universe?

It's like saying a charcoal sketch of a person 'means' the person.

I know those aren't the whole, or even true cosmologies, but I'm talking about the word in and of itself. If I were talking about a universe's "cosmology", wouldn't I be talking about it's spacetime, matter/energy, and physical laws/constants, as I am talking about it as a totality, including it's beginning and end?

Cosmology literally means 'study of the cosmos'

Cosmos being Universe.

And here I thought this was a thread directed towards me. Turns out it has nothing to do with physics. Oh well.

You think any thread regarding physics is directed at you?

Have you not noticed his enormous ego that makes it treat everything as a direct personal threat?

No. As explained below. The cosmological model wouldn't suffice either as it's simply a theoretical model based off our understanding of the universe.

I mean if someone were able to "rewrite the cosmology of their universe", what would that imply? What would they be able to affect, and on what scale?

You don't understand what the word means.

Wikipedia defines Physical Cosmology as "the study of the largest-scale structures and dynamics of the universe and is concerned with fundamental questions about its formation and evolution"

I don't know which term to use. What if I said "rewrite physical laws and constants"? Would that include spacetime and matter/energy? I need a term that is all-compassing. Thank you for the assistance

"rewrite the physical laws of the universe" would probably work, "constraints" is redundant in that phrase.

"physical constants"

the laws are what constrain things; or, constraints are a product of the laws

But when I say "physical laws", that includes spacetime, and matter and energy?

There are far more mathematical models of the universe, than there are universes.

avoiding a conversation about what phenomenon may or may not be a product of our universe, yes, I believe so

So if I were to say "one could rewrite the laws of physics anyway they wished, even if physically, mathematically, or logically impossible", that would intrinsically imply within it "omnipotent control over matter and energy"?
