I understand that we build models and do calculations but aren’t there any potential errors/assumptions? That accumulate over multiple calculations and grow bigger the further we go back or over distance?
I.e. “At approximately 10−37 seconds into the expansion, a phase transition caused a cosmic inflation, during which the universe grew exponentially, unconstrained by the light speed invariance, and temperatures dropped by a factor of 100,000.”

We don’t, not even close. There are a handful of examples of things like universal constants where we know the *exact* number, but far more where we *don’t*. I can’t sit here and list them all out for you, but just know that we very much do NOT know everything in the universe *at* *all,* let alone with any amount of precision. I mean we can’t even date ancient artifacts from a few thousand years ago without at least some range of error.
