Energy-Momentum Transfer and the Quantum Potential

Abstract

This chapter deals with a number of important conceptual issues and some theoretical problems of the Causal Theory. Contrary to claims in the literature, it is shown that energy conservation does hold in the Causal Theory. The function and role of the quantum potential is described in some detail with particular reference to the case of a Gaussian wave field. A novel explanation is developed of how quantum particles can ‘tunnel’ out of a finite potential well. Arguments are made in favour of the absence of a classical reaction for quantum entities. An account is outlined of what occurs physically when a measurement is made on a quantum system. Reasons are advanced for granting the same ontological status upon the quantum mechanical force as is given to the accepted fundamental forces of nature. A possible experimental test of the Causal Theory is suggested and some empirical consequences considered.
