Indeed. In all the history of Science?
Not one time, has the Peer Review process had to go back and say, "well. This was unexpected! The <holy text> had it correct after all, and we were wrong!"
That never happened. In fact, it's rare that the Peer Review will look at an established theory, and conclude: "Well. That's it for Newton, then! Toss out all the Newtonian Textbooks-- they are now garbage. Clean Slate from now on, Only Einstein!"
Instead? Scientists have discovered where Newton's Model no longer works very well.
That does not mean it never works at all! It simply means if you push the limits, and try to apply Newton's Model, your predictions will be off.
So, in a way, Relativity could be seen as a kind of refinement of Newton: If you have very high relative speeds, or very-very large masses, or very deep gravity wells, or very lengthy time frames? Newton does not work very well.
