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

Every physicist on the planet would be overjoyed, as long as the new equations hold up to testing the same way. Scientists dont tend to be bothered by new information or being proved wrong.
