Are There Dynamical Laws?
Abstract
The nature of a physical law is examined, and it is suggested that there may not be any fundamental dynamical laws. This explains the intrinsic indeterminism of quantum theory. The probabilities for transition from a given initial state to a final state then depends on the quantum geometry that is determined by symmetries, which may exist as relations between states in the absence of dynamical laws. This enables the experimentally well confirmed quantum probabilities to be derived from the geometry of Hilbert space, and gives rise to effective probabilistic laws. An arrow of time which is consistent with the one given by the second law of thermodynamics, regarded as an effective law, is obtained. Symmetries are used as the basis for a new proposed paradigm of physics. This gives rise naturally to the gravitational and gauge fields from the symmetry group of the standard model, and a general procedure for obtaining interactions from any symmetry group.
