Whatever our universe "really" is at the core, what we do know is that its physical rules have been constant since shortly after the Big Bang
We don't "know" that at all. The Big Bang is a mountain of speculation, many erroneous assumptions, and it has been falsified a dozen times over. Yet "scientists" who do not own an Occam's razor persist in the dogma that "even if" the theory is faulty, there are no
alternatives to consider. So they'll stick with Big Bang since it explains observed phenomena "well enough." Among the many internal inconsistencies is the notion that physical rules have not
been constant since the "Bang" (e.g. the faster-than-light "inflationary" period).
I said "shortly after," so I don't know what that
little rant of yours was motivated by.
