Scientists generally proceed on the basis that physical laws are constant at all locations in the Universe.
That's why Einstein didn't believe in so-called "black holes". Einstein clearly stated in his theory that the physical laws of the Universe are the same at ALL locations in the Universe. So-called "black holes" and the "big bang" specifically rely on physical laws being set aside.
There is an arrogance present when a hypothesis based on a priori, mathematical equations attempts to trump the recognized principle in science that the physical laws of the Universe are immutable and constant.
"But black holes exist, the big bang happened, if the physical laws have to be set aside to preserve these ideaswell, I guess the physical laws will have to be put aside."
So says the "modern" astronomer.
