Quantum darwinism
p2pnet.net OT News:- Some US physicists believe they know how our objective, common reality, “emerges from the subtle and sensitive quantum world,” says Nature.
“If, as quantum mechanics says, observing the world tends to change it, how is it that we can agree on anything at all?” – asks the magazine. “Why doesn’t each person leave a slightly different version of the world for the next person to find?”
“Because, say the researchers, 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.
If it wasn’t for quantum darwinism, the researchers suggest, “the world would be very unpredictable: different people might see very different versions of it. Life itself would then be hard to conduct, because we would not be able to obtain reliable information about our surroundings… it would typically conflict with what others were experiencing.”
Well, er …..

There was a three hour special this week on Nova about quantum theory. It was a bit dumbed down of course, but that made it no less interesting. This article fits in pretty well with the rest of it and makes for interesting reading. If it didn’t get a comment here at p2pnet, I would have missed it completely. Thanks!
