People say, "Oh, see scientists, we thought this was right and now we all cuddle around this thing that's right." That is not how it works.
The way it works is if you have an experimentally determined result and it's verified and double-checked and triple-checked, that will not later be shown to be false. What you can find is a deeper understanding of the world that encloses that understanding.
That's what happened with Einstein. Einstein's theories of motion and gravity. If you put in low speeds and low gravity in the equations, they become Newton's equation. So Newton's universe is a subset, an accurately described subset of a larger universe that Einstein has described. And even with Einstein, his equations can't take us to the center of a black hole.
