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?

Newton even said there was a force acting from a distant, he just did not know what that was. Einstein was basically gravity tells space/time how to form, and that space/time tells matter how to move and we got that action from a distance so it was in a way clearing up what he started.
It did not end there either the debate about gravitational waves was ongoing, how fast they could travel, if we could ever detect them or not. Who is to say the speed of light truly is the speed limit of the universe. For now we can just say with our understanding of it, it is.
If/when we figure out dark matter how will that change our understanding of the universe. Do we find a way to bypass the speed of light, or do we just get the cool looking hover cars in sci-fi without producing downward thrust. Wont know until we get there.
