The Duality of Time Theory

The transactional interpretation was introduced by John G. Cramer in 1986, inspired by the Wheeler-Feynman absorber theory. It describes a quantum interaction in terms of a standing wave formed by the sum of a retarded, forward-in-time, and an advanced, backward-in-time, wave. The author argues that it avoids the philosophical problems with the Copenhagen interpretation and the role of the observer, and resolves various quantum paradoxes.
