First and foremost, [[Quantum Mechanics|quantum mechanics]] is a mathematical framework that predicts how particles at the smallest scale behave. The theory predicts values that we are expecting to see in an experiment. In this regard, quantum mechanics is one of the best tested theories to date. However, when using the formalism, the question of meaning naturally occurs: do [[Wave Function|wave functions]] really exist in Nature or are they just a statement of our knowledge about the process at hand? What does it mean to observe and what does it mean that a wavefunction collapses? These questions are hard to test since they usually do not lead to a difference in the prediction: if both so-called *interpretations of quantum mechanics* use the same mathematical tools and yield the same number as outcome for an experiment, it is impossible to distinguish them in experiment. In quantum mechanics, there are many different interpretations with famous scientists advocating for them. Some examples are - [[Multi-World Interpretation]] - [[Superdeterminism]] - [[Copenhagen Interpretation]] - [[Bohmian Mechanics]] - [[Q-Bism]] >[!read]- Further Reading >- [[Quantum Mechanics]] >[!ref]- References
