Quantum theory Quote by Lee Smolin
““The key question for a quantum theory of gravity is then the following: Can we extend to quantum theory the principle that space has no fixed geometry? That is, can we make quantum theory background-independent, at least with regard to the geometry of space? If we can do this, we will automatically merge gravity and quantum theory, because gravity is already understood to be an aspect of dynamical spacetime geometry.””

The quest is to formulate a quantum theory where spacetime geometry is not fixed but dynamic.
In simple terms: Make quantum theory work without a preset space shape.
