Abstract: | It seems likely that quantum dynamical law doesnot have a separate objective existence, but is oneaspect of the quantum process of nature, amatter-spacetime-dynamics unity, and is not onlyvariable, but may be the only variable. This is oneresult of a systematic application of the criteria fora group contraction given by Inonu and Wigner (1952).They point out that nonsemisimplicity is circumstantial evidence for a group contraction in which somecoupling coefficient has been taken to a singular limit.In their example, the coupling coefficient is c and thegroup contraction c passes from special to Galilean relativity. |
