RUTA said:I'm not sure I understand what you are describing. You're not thinking about the wavefunction on a 3 sphere, are you? The wave function for N particles exists in a space with 3N dimensions, so it doesn't map into the space of spacetime unless you're only talking about one particle.
You must understand this one basic point, or nothing else will make any sense:
Schrodinger equation = Laplace's equation:
http://en.wikipedia.org/wiki/Laplace's_equation
If you do not understand me when I say that all we are looking for is a simple, harmonic standing-wave solution to the Laplace equation (i.e. we can understand this as a pure "eigenstate"), then the entire logical foundation of this entire theory falls apart.
In other words, wavefunctions, qua themselves, have nothing whatever to do with particles. All that a wavefunction does is to tell its infinitesimal spaces how to oscillate. This is easy to observe in the 1 and 2 dimensional cases when we look at harmonically oscillating guitar strings and drumpads. But in order to construct our own 3D universe, it is necessary that we solve this equation for all three dimensions. But the problem here is that we cannot visualize the infinitesimal spaces (tiny volumes in this instance) as extending into another dimension, as with the 1 dimensional case when we see the parts of the wave extending into the second dimension. So, for this oscillating extension to make sense, we have to "bend" the flat 3D space so that it becomes a superficial manifold within a logical fourth dimension.
Now, the "typical" manifestations of the Schrodinger equation are just this very same principle, but only applied to the trajectories of "material points." However, this entire picture is simply the very same thing as the classical, Newtonian model wherein bodies move on simple, parabolic paths through space. The only difference is that it is now the Schrodinger/Laplace equation that governs the movements of particles rather than Newton's classical equations of motion.
It is vital to understand that the only thing that conceptually distinguishes quantum theory from classical kinematics is the idea of harmonically oscillating, space-filling standing waves. If we simply want to "interpret" this notion so that it degenerates back into a kind of "weird" classical model, then that is our right, but we will have ultimately gained nothing from it.
So my project is to get you guys to see the folly in this kind of "interpretive" behaviour, and just start to embrace the utter beauty and simplicity of the things that we call "standing waves." And once we do this, then we can start to realize that anything is possible in terms of coming up with "manifestly believable" models of physical reality. So then, if you can go back and reread what I have already written in terms of the paradigm of "pure waves" rather than "crazily moving particles," then you will be able to start to visualize in your own head what the mathematical object that is known as 'U' is telling you.
