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

There is certainly something that will explain it further. The reason for this is because einstein’s theory breaks down. You’re wrong in thinking that einstein disprove newton. Think of it as einstein’s calculation just being more precise. Newton’s equation works up to a certain time and distance (normal every day stuff). If you use einstein’s equations at those time and distance you’ll get the same thing. The future stuff will encompass einstein’s calculations and just expand on it.
