Love and Quantum Entanglement

Interesting discussion on NPR radio on how relationships can effect health through "quantum entanglement."

Once two particles have interacted, if you separate them, even by miles, they behave as if they're still connected. So far, this has only been demonstrated on the subatomic level.

But Radin wonders: Could people in close relationships — couples, siblings, parent and child — also be "entangled"? Not just emotionally, and psychologically — but also physically?

"If it is true that entanglement actually persists, by means of which we don't understand," he says, "if they are physically entangled, you should be able to separate them, poke one, and see the other one flinch."
This idea — that we may be connected at some molecular level — echoes the words of mystics down the ages. And it appeals to some scientists.

But it infuriates others — like Columbia University's Sloan. The underlying idea is wrong, he says. Entanglement just doesn't work this way.

"Physicists are very clear that the relationship is purely correlational and not causal," Sloan says. "There is nothing causal about quantum entanglement. It's good to be open-minded, but not so open-minded that your brains fall out."
