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

All theories are an approximation to reality. None of them including Einstien are absolutely true. They are usually good enough to work with. The basic problem with Einstein’s General Theory of Relativity is that it isn’t a quantum theory.
