The Secret Connection Between Past and Future in the Quantum World ⚡ экспресс
By generalizing Bell's hidden-variable model to more dimensions, the authors gave physical meaning to one of the variables — a state evolving backward in time. With a simple deterministic rule, symmetric in time, they derived the Born rule for quantum probabilities. Randomness emerges as an averaging over future states propagating into the past. Like a weather forecast where tomorrow's conditions influence the chance of rain today, the future determines quantum events.
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.
