Quantum theory applies to everything. It even explains how larger objects (as in, much larger than the molecular level) act very similar to Newtonian principles, as the mass of an object affects the waves as shown in Feynman's infinite histories. Basically, each possible outcome (of which there are infinite) translates into a spot on a wave. Outcomes that are similar to each other are also very close on the wave (i.e., both on the crest), and therefore reinforce each other. But there are some outcomes which are opposing each other (e.g., X molecule randomly deciding to turn right 90 degrees and fly off in that direction and X doing the same thing to the left side) are on opposing sides of the wave, thus essentially canceling each other out. The potential outcome of objects with higher mass are much more in sync with each other for the outcome that old Newtonian principles would predict. There is still a level of randomness, but not nearly as much.

And the uncertainty principle applies to everything as well. But when measuring large objects (say, a soccer ball or a car), the units we use to measure its location (even millimeters) do not come close to reaching all of the zeros in Planck's constant (the maximum amount of certainty we can have of an object's location and velocity). That number is really, really small, and even measuring in millimeters and meters per second don't come even close to reaching that level of certainty. But this does have a profound effect on locating molecules, and, interestingly enough, the uncertainty principle also shows that there is no such thing as empty space -- and that even if we can't see or measure anything, matter is constantly, in lay terms, popping in and out of existence.

So yes, Bleys is right. For once. Someone should alert the press.

I find this subject much more interesting than the time travel discussion.
