Scientists link common reality to quantum physics:
[World News]: Washington, Dec 30 : Have you ever wondered why different people don't see the world differently? According to a team of scientist from the Los Alamos National Laboratory in New Mexico, the answer lies in quantum mechanics.
The researchers, whose findings were published in the "Physical Review Letters," our objective, common reality emerges from the subtle and sensitive quantum world.
They say that certain special states of a system are promoted above others by a quantum form of natural selection, which they call quantum Darwinism.
Information about these states proliferates and gets imprinted on the environment. So observers coming along and looking at the environment in order to get a picture of the world tend to see the same 'preferred' states.
They say that the that macroscopic or classical world emerges from the quantum world of many possible states through a phenomenon called decoherence, according to which interactions between the quantum states of the system of interest and its environment serve to 'collapse' those states into a single outcome. But this process of decoherence still isn't fully understood.
"Decoherence selects out of the quantum 'mush' states that are stable, that can withstand the scrutiny of the environment without getting perturbed," the researchers wrote in their study. (ANI)
