For over a century, quantum mechanics has challenged our established notions of physics. At the heart of this problem are questions that disrupt our understanding of the universe: when does a quantum particle take on a defined state? Like Schrödinger’s famous feline, the properties of an object seem to depend on observation. But the enigma extends further: does such a particle instantly influence distant entities, defying any localized interaction? Einstein dubbed this “spooky action at a distance.” Exploring these quantum puzzles reshapes our understanding of reality, pushing the boundaries of what is locally real.
