Quantum Interpretations

Welcome to the Quantum Interpretations forum!

Discuss the foundations of Quantum Mechanics as a theory structure and different published interpretations of Quantum Mechanics.

Interpretations of quantum mechanics are a way to explain how the mathematical theory of quantum mechanics "corresponds" to reality.

These discussions present unique challenges since they deal with matters for which there is not an established "right" answer that has been confirmed by experiment and is generally accepted by scientists in the field. As a result, such discussions do not usually reach a fairly quick resolution, and often do not reach a resolution at all.
