[plain talk]

What's not explained very well in this article is how one sets up particles at different parts of the universe to respond to one another. I sort of understand the concept but don't understand what allows one particle to respond to another when they are separated at great distances.

That is the rub. One has to entangle the particles, separate them, at less than the speed of light, and then, once separated, start measuring properties. The last part could communicate information at greater than the speed of light. This process might allow a space ship, traveling a less than the speed of light, communicate instantaneously with home as it traveled.
