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

Because in science it is encouraged to test out anything and everything. Scientists tested out Einstein’s Theory or Relativity by taking an atomic clock in outer space, and comparing it with an atomic clock on the Earth’s surface. They found that the two clocks diverged by a few nanoseconds.
