## Main Question or Discussion Point

Let us say we find the position of an electron at time

*t*to be here on earth. An instant before this, the electron must have been here on earth as well since nothing can travel faster then 670 million miles per hour. In other words the electron does have a speed limit, so 1 x 10^-15 seconds prior to locating the electron on earth, there would be no other place that the electron could have existed. The problem is that this instant before we discovered its position, quantum mechanic equations provide a probability that the same electron was on the dark side of the moon. Why does Quantum Mechanics provide us with a probability that seems to be an impossibility?
