Motion of the photon proved the existence of the past and the future at the same time

(ORDO NEWS) — Scientists at Oxford University have made an unexpected discovery and managed to prove the existence of the past and future for photon particles at the same time.

The article was published by the journal Communication Physics.

The team of physicist Giulio Ciribella discovered a single movement of parallel processes in two directions.

The proof was the movement of photons moving forward and backward in time, which was called “quantum time reversal”.

The researchers said that the usual ideas about time are simply erased at the microscopic level.

Through experiment, they proved that quantum time reversal is possible. They took a photon splitter, where each particle of light is split into two paths through the crystal, one going from right to left, the other in the opposite direction.

Scientists could not determine the direction of the photons until they came to an unexpected conclusion. They proved statistically that photons are necessarily in a superposition of paths and in two time processes at the same time.

Experts say that these results allow us to simulate a hypothetical scenario when the arrow of time can be in a quantum superposition.

Chiribella and his colleagues believe that their discovery will lead to other innovations and even to the creation of a new theory of quantum gravity.
