Quantum Theory vs Macroscopic Realism
Quantum theory allows for an object to be in two different states at the same time. This is described as a super position state, which combines different observable states. But could this really be true? Or could the particle be in a very specific state, at a very specific location and we just can’t observe it? The behavior of quantum objects has been discussed using a very simple classical theory. In 1985, the “Leggett-Garg Inequality” was first introduced as a way to measure quantum behavior. It states, in effect, any theory that describes particle behavior without the superposition states in quantum theory must obey the Leggett-Garg inequality. The inequality is fulfilled by all macrorealistic physical theories. macroscopic realism is a classical world view defined by the joining of these two hypotheses. "A macroscopic object, which has available to it two or more macroscopically distinct states, is at any giv...
