Scientists could have achieved the equivalent of a “time machine” by scattering electrons effectively against the direction of time.
It may not be the Tardis, a time machine that appears in Doctor Who, but physicists have loosely described as moving in the opposite direction of “time’s arrow”.
The team worked with electrons in the realm of quantum mechanics and achieved the equivalent of causing a broken rack of pool balls to re-order itself.
Researchers, from the Laboratory of the Physics from Moscow Institute of Physics & Technology (MIPT), say that they have effectively defied the second law of thermodynamics.
This is the branch of physical science which governs the direction of from past to future.
The balls scattered randomly around the pool table went into reverse and packed themselves back into their original pyramid formation.
To an outside observer, it looks as if time is running backwards, said lead researcher Dr Gordey Lesovik, who heads the laboratory of the Physics of Quantum Information.
“We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time”.
