A very important idea in General Relativity is, same laws in all reference frames.
How does that work in rotating reference frames?

This is a time-worn question with a simple answer. Special relativity is not restricted to inertial reference frames. The equations of electromagnetism, relativistic mechanics, etc, can just as well be written in a curvilinear coordinate system, and you are still doing special relativity. You haven't changed the physics merely by using curvilinear coordinates!A very important idea in General Relativity is, same laws in all reference frames.

you said: "The laws of physics are the same in both coordinate systems."
Then how are centrifugal forces explained in the "rotating" frame?
General Relativity is a theory of gravity proposed by Albert Einstein in 1915. It describes how the force of gravity is a result of the curvature of space and time caused by the presence of massive objects.
In GR, all frames of reference refer to any observer or reference point in the universe. This means that the theory applies to all objects, whether they are stationary or in motion, and from any perspective or point of view.
Newton's theory of gravity describes the force of gravity as a pull between two objects with mass. GR, on the other hand, explains gravity as the curvature of space and time caused by the presence of matter and energy.
GR has been used to accurately predict the orbits of planets, the bending of light around massive objects, and the existence of black holes. It also plays a crucial role in modern technologies such as satellite navigation and GPS systems.
Scientists are currently working on incorporating GR into a theory of quantum mechanics to better understand the fundamental workings of the universe. Additionally, researchers are studying the effects of GR in extreme conditions, such as near the event horizon of a black hole.
