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?

We actually already know he didn’t have it truly correct.
He got a bit closer to describing a bit of reality than Newton did. We still use Newtons theories, because if you want to build a bridge, they work fine and are easier to work with.
If you want to build a rocket, you want Einstien level works.
But people building rockets are somewhat aware that his theorems aren’t how things really work, they are just close enough that they will do.
If you want to build a particle reactor, you need to think about post-Einstien quantum mechanics, and some very fiddly new theories indeed. And if we don’t break our high tech society, one day, we shall likely need to work with yet another set of theories, but stick to the old simple ones for such down to earth stuff as particle accelerators.
