Ah yes, that’s why the equations make that n-dimensional trick to avoid the need for a single spot for the explosion’s ground zero. No, there’s no need right now for complications beyond Newton’s laws for this particular problem.
That’s a very interesting question. Can one really say that Earth is not the center of the solar system? What the equations say is only that the calculations are simpler if one assumes the Sun to be the center. The orbits come up “prettier”, that is elliptical instead of lemniscates or whatever. But is that right? Yes. And no. In the end, under this rule, the only thing we know is “the calculations fit”. There is an entire set of calculations where the Earth is the center of the universe. And, mathematically, they’re right. There’s another set where the Horsehead nebula is the center. None are particularly elegant.
What does it mean when we say Big Bang is scientifically sound? It means the same thing: “the calculations fit”. In those calculations there’s no particular “center of explosion”. That’s because the calculations were made based on the observation or lackthereof of said center.
