/sci ... is this true or woo?

There is a principle in physics that states that any event that is not prohibited by the laws of physics should happen! What, then, happens to the pendulum? All the points on it behave the same way; therefore, all of it must for a tiny fraction of a second move at infinite velocity. Can a physical object move faster than the velocity of light?

Let us approach this from a different angle. We have heard about Heisenberg’s principle of uncertainty. This principle states that in trying to measure two parameters of a particle—for instance, its momentum and its position—we find that the more accurately we can measure its momentum, the less we can know about its position, and vice versa. (Momentum simply means: mass x velocity.)

If we want to measure either the momentum or the position of a particle, we can measure precisely only one of these quantities. If we know the exact momentum of a particle, then its position is completely indefinite or unknowable, and vice versa. This is an example of those strange ways in which particles of atomic size or smaller behave.
