The Duality of Time Theory

There are two quantum informational approaches: information ontology, and epistemology. The latter describes an observer’s knowledge of the world, rather than the world itself, while the first have been described as a revival of immaterialism, such as the concept of John Wheeler (1911-2008): “it from bit”.

According to these views, the quantum mechanical state is not an objective property of an individual system, rather: it is the information obtained from a knowledge of how a system was prepared, which can be used for making predictions about future measurements. So it is a summary of the observer’s information about an individual physical system changes both by dynamical laws, and whenever the observer acquires new information about the system through the process of measurement. The existence of two laws for the evolution of the state vector becomes problematical only if it is believed that the state vector is an objective property of the system. The “reduction of the wavepacket” does take place in the consciousness of the observer, not because of any unique physical process which takes place there, but only because the state is a construct of the observer and not an objective property of the physical system.
