= Background independence
{wiki=Background_independence}
Background independence is a concept primarily used in theoretical physics, particularly in the context of general relativity and quantum gravity. It refers to the idea that the laws of physics should not depend on a fixed background structure, such as spacetime itself. In other words, the theory should be formulated in such a way that the geometry of spacetime is not predetermined or fixed, but rather emerges from the physical processes described by the theory.
