A talk given by Prof. Ravi Gomatam at the DPG Frühjahrstagung (Spring Meeting) of the Matter and Cosmos Section, German Physical Society University of Bremen, March 2017 Abstract: Physics at present treats observations, not as our experiences, but as objective physical events in the external world. This reduction, achieved via the assumption of naïve realism (NR), has served well both in the classical physics and microscopic quantum mechanics (QM). However, when the same QM is extended to the macroscopic regime, naïve realism drastically breaks down at the point of observations, as shown by the famous cat paradox. This is because historically QM developed by presupposing the classicality of the macro world via NR. The measurement problem is a direct result of assuming NR. The Schrodinger equation demands superposition of the wave function, but the classical macro world of determinate pointer states cannot become superposed. Eschewing NR will immediately render the observations to be just our experiences. This step leads to two other benefits: physics will become truly empirical; and experiences can superpose. The only mystery in QM then would be: how to objectivize our observations qua experiences, without NR, for doing physics. I motivate a new conception of quantum information called Objective Semantic Information ©, that could help solve this mystery.
