The thing is these theories often led to us being able to do something practical with the knowledge. Our understanding of physics has led us to invent air travel, cars, nuclear energy and more. So even if we've made a fundamental mistake somewhere we must be correct about the aspects of how these concepts relate to each other.

As I said we can only measure and observe the world we see and work within the parameters given. The idea there could be something outside of that which would invalidate it (other dimensions, other forces, God) is useless to science as we can't test it. So it's an irrelevance as far as scientific research goes....
