How do we know Einstein has it right?

Question

We constantly say that Einstein’s General and Special theories of relativity have passed many different tests, insenuating their accuracy.

Before Einsten, we tested Isaac Newton’s theories, which also passed with accuracy until Einstein came along.

What’s to say another Einstein/Newton comes along 200-300 years from now to dispute Einstein’s theories?

Is that even possible or are his theories grounded in certainty at this point?

Answer 1

These theories are descriptive, not prescriptive. They are grounded in a limited reality. Newtonian stuff works in its own “bubble”, but it comes short in broader application. Einstein’s theories have far more applications but it’s not the end or a theory of everything and one day someone will surely surpass Einstein as he surpassed Newton.
