In a unique experiment, an international group of scientists stated that it is possible to turn back the clock without violating the second law of thermodynamics. It States that for all spontaneous processes in nature characteristic of one-pointedness. For example, hot bodies, over time, inevitably cooled, at the same time cold by themselves will never heat up.
However, scientists managed to prove that this thermodynamic “arrow of time” is not an absolute concept. During the experiment they used the correlated particles, is conceptually similar to entangled particles that are used during the quantum research.
Researchers began the experiment with trichlormethane molecule composed of hydrogen and carbon. They made the nucleus of the hydrogen atom is more warm compared to the carbon atom, and to observe the flow of energy.
While the kernel was neskorrigirovannoe, the warmth spread as it should be – from the hot core to the cold, but as soon as they were skorrelirovany, heat has flowed back, back to the hot core, what made it even hotter and the cold colder.
According to studies, the studies of the second law of thermodynamics was not violated because it does not account for correlated particles. In other words, the experiment recorded only the exception to the rule.
