Poor description all around. You aren't *changing* properties. You are measuring one of a pair of "related" properties. Until you make the mesaurement said properties do not have a value. Really. They've proved this experimentally via some interesting tests. But measuring it on one particle means that since the particles are entangled, the other one must have the same value. So it is instantaneous. It's an example of quantum non-locality. And yes, the experiments ruled out "speed of light" changes too. -- Leonard Erickson (aka shadow) shadow at shadowgard dot com
