Unintended consequences of time travel, known as “the butterfly effect”, may have a role in science fiction, but not in physics, scientists have proved.
“The butterfly effect” — the property of certain chaotic systems, consisting in the fact that a minor effect on the system can have significant and unpredictable consequences, including in a completely different place)
Scientists from the Los Alamos national laboratory in the US created a simulation using a quantum computer IBM-Q.
“On a quantum computer there are no problems with simulation of evolution in a reverse order or a simulation process is run in the direction of the past,” says physicist Nikolai Sinitsyn.
It turned out that a small scene consisting of a correlated quantum States, enough to play event with a tiny change and understand that change.
“So we can see what happens with a complex quantum world, if we travel back in time, make small changes and go back. We found that our world remains, that means that in quantum mechanics there is no butterfly effect,” — said Sinitsyn. “The damage does not increase in the decoding process,” adds colleague Sinitsyna Bin Yang.
“We found that the concept of chaos in classical physics and quantum mechanics must be understood differently,” — said Sinitsyn.
Previously, scientists have found evidence that before our Universe there was another.
