Move over Doctor Who: Scientists have effectively created a 'time machine' that goes in the opposite direction of times arrow
time machine' that moves tiny particles a fraction of a second into the past was built in Russia, scientists have claimed.
It may not rival Dr Who's Tardis but researchers have described it as being able to move the smaller than atom sized objects in the opposite direction of 'time's arrow'.
The experiments involved electrons - negatively charged particles that make up an atom - found in the realm of quantum mechanics, the study of sub-atomic particles.
They gave the analogy of a break for a game of pool, in which the balls are substitutes for the electrons.
After the break the 'balls' are scattered in what should be a haphazard way, according to the laws of physics.
But researchers managed to make them reform in their original triangle 'break' order - appearing as if they were turning back time - using a special quantum computer.
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 with the experiment.
This is a rule within physics that governs the direction of events from the past to the future, stating that everything in our universe tends towards decay.
The 'time machine' is built from a basic quantum computer, which is made up of 'qubits'.
These are units of information described by a 'one', a 'zero', or a mixed 'superposition' of both, that can be stored on an electron.
In the experiment an 'evolution program' was launched which caused the qubits to become an increasingly complex changing pattern of zeros and ones.
During this process, order was lost - just as it is when the pool balls are struck and scattered with a cue. Another program then modified the state of the quantum computer in such a way that it evolved 'backwards', from chaos to order.
