When faced with weird quantum effects, many physicists are content to just calculate the probabilities of experimental outcomes using the Schrödinger wave equation. But does that approach explain why particles behave like waves or how entanglement is maintained over large distances? Or is the math just a computational tool that hides our lack of a fundamental understanding of quantum phenomena? Researchers working on the foundations of physics are hoping to reveal a causal explanation of quantum mechanics by diagramming the elements within an experiment.
