A wave function is the probabilistic measure of a superposition. To the extent that a wave function is collapsed, the superposition is also proportionally collapsed. The collapse of a wave function only occurs when a quantum measurement is taken.

My concept of wave function as a probability spread comes from Mr Richard P. Feynman's April 3rd, 1962 lecture about the Thomas Young double slit experiment. I have the Six Easy Pieces CD set. Superposition, of course, comes from the Copenhagen interpretation that say's the particle actually does go through both slit's. I was guessing about "wave function collapse".

Any and all quantum measurements are subject to the uncertainty principle, that the product of the uncertainty in the quanta's position and the uncertainty in the quanta's velocity must be greater than Planck's constant. If we measure the quanta's position with complete accuracy, we have stopped it dead and have zero data concerning it's velocity. If we measure the quanta's velocity with complete accuracy, we have measured some effect of it's passing without interacting with the quanta in the slightest, and have zero data concerning it's position.

All of that is an attempted explanation of; (Delta x)(Delta p)=>h. That formulation also came from Six Easy Pieces.

Since any measurement of a quanta, even as static data, still contains the probability spread of the inherent uncertainty, the wave function is never wholly collapsed. The uncertainty of a system of multiple quanta will equal, not the sum of uncertainty's, But the product of the uncertainty's. Therefore, where the total collapse of a single wave function or superposition is theoretically impossible, the total collapse of a system of wave function's or superpositions is several orders of theoretically impossible.

And here I have blurred the line between data and reality, admittedly violating my own precept. That the map is not the territory. But in the first chapter of his book, "The Road To Reality", Mr Penrose discusses Platonic philosophy. Sinned as the greats I have.

In quantum physics, all forces, except gravity, are actuated through the exchange of quanta between quanta. The collapse of the wave function of the system would result in the disexistentiation of the quanta and thus also the forces.

In the standard model, forces are mediated with particles. Photons are exchanged in electroweak interactions. Gluons mediate the color force. And I forget the rest.

Admittedly, half of what I said, I made up. But consider the post I was answering. Poor Mr schiz0id was barking up the wrong tree in the wrong forest. While I cannot yet help him find the right tree, I can point him to the correct forest.

If you, Mr DrRocket, would learn to speak halfwit, than many halfwit's might learn some trig' maybe? A^2+B^2=C^2. Or in English; The sum of the squares of the two sides of a right angle triangle must equal the square of the hypotenuse. Funny thing about the Pythagorean's, they didn't believe in irrational numbers.
