Background independence is a condition in theoretical physics, especially in quantum gravity (QG), that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime, and in particular to not refer to a specific coordinate system or metric. The different configurations (or backgrounds) should be obtained as different solutions of the underlying equations.

Famous quotes containing the words background and/or independence:
“... every experience in life enriches one’s background and should teach valuable lessons.”
—Mary Barnett Gilson (1877–?)
“The [nineteenth-century] young men who were Puritans in politics were anti-Puritans in literature. They were willing to die for the independence of Poland or the Manchester Fenians; and they relaxed their tension by voluptuous reading in Swinburne.”
