As is evident from von Baeyer’s article, quantum theory truly challenges us to think outside the box—and, in this case, I submit that the box is spacetime itself. If this seems farfetched, consider the eloquent point made by physicist and philosopher Ernan McMullin:
“Imaginability must not be made the test for ontology. The realist claim is that the scientist is discovering the structures of the world; it is not required in addition that these structures be imaginable in the categories of the macroworld.”
Only if we face the strange non-classical features of the physical world head-on can we have a physical, non-observer-dependent account of our reality that solves longstanding puzzles such as the problem of Schrödinger’s Cat.
