The Secret Connection Between Past and Future in the Quantum World ⚡ экспресс
A two-state vector formalism in quantum mechanics is introduced by generalizing Bell's hidden-variable model to higher dimensions. The hidden variable is given the physical meaning of a state evolving backward in time. A simple deterministic and time-symmetric rule for measurement outcomes is proposed, from which the Born rule is derived. It is shown that probabilistic results follow from deterministic assignment and averaging over future states propagating back to the present. This rule provides an alternative formulation and proof of the Pusey-Barrett-Rudolph theorem.
A typical recipe explains how to cook a dish. The new approach turns the logic around: the future pie itself dictates how much flour to add now. In the quantum world, researchers suggest, a particle receives signals from the future outcome of a measurement. That outcome determines what we see in the experiment.
Physicists, including John Stewart Bell, spent decades searching for the source of quantum randomness. A model with reverse time not only explains it but also serves as alternative proof: quantum states are not a computational trick but reality.
It’s akin to warping of time on microscopic scales. The rules of the Standard Model gain meaning if time flows both ways. No signal travels faster than light, and entropy is a measure of our ignorance of these backward influences.
🎯 The main law of quantum physics that predicts probabilities was taken on faith for almost a century—and only today is it being derived from the idea of the future's influence.
🎬 This work echoes the ideas of the film Tenet, where the future influences the past, but here everything stays strictly within science.
