Change in one particle affects change in the other entwined particle, no matter how far apart that they have been spaced.
Faster than the speed of light.
It thus appears that one particle of an entangled pair "knows" what measurement has been performed on the other, and with what outcome, even though there is no known means for such information to be communicated between the particles, which at the time of measurement may be separated by arbitrarily large distances.
The working of matter, at the subatomic level, transcends out understanding, in real time, of space.
