When we reviewed the single slit experiment, we found literally two types of probability at work - one form leads to how matter waves travel, and the other form leads to how they collapse. It is easy to lump both these into one form of mundane probability. This is what has been done... which leads to mundane results. However, this isn't what is really happening - we find probability of travel, P2, is not the same as probability of collapse, P1. This leads to some interesting conclusions, and gets us one step closer to FTL communications. This is how the universe does it, and this is how we can do it too.

First, knowing that when we are talking about 'real' particles, we are really talking about complex entities - things that have both real and imaginary sides to them - which is what everything 'real' in the universe is. Also that both sides of complex particles play valuable roles in our universe. Either together, or alone. When a complex wave function collapses, a real particle is formed. It no longer has an imaginary characteristic. Most people are fine at this point - dealing with imaginary quantities just gets in the way. Electrical Engineers, for example, know full well their electronics equations have an imaginary component, but it just gets thrown away, and their applications -- integrated circuits, semiconductor lasers, cell phones, hair dryers -- work just fine. These are the components of our mundane existence - and for most tech fields, pretending complex is real will work out just fine. But, physics is the mother of all science. We can not afford to be so glib about the imaginary. Both the real and the imaginary must be dealt with in equal measure - even if most physicists might wish otherwise. This is our inheritance from the 20th century.

The single slit experiment has revealed another side to reality on the most fundamental level. Now, we have always known that imaginary quantities are needed... they just weren't liked very much, is all. For example, one I've said before, is the way imaginary particles mediate and weaken the nuclear forces. Though the nuclear force is so short range it only acts inside the atom, it is responsible for radioactive decay, and atomic stability in general. Without imaginary particles, this force would be much stronger and the particles that make up atoms would squeeze together so hard they would form black holes. Another is that simple probability is not so simple after all. There are at least two forms probability can take, P1 and P2. They are so relational that they can be combined and the results of experiment will remain valid. We know better. Separate, unanswerable questions become easy to understand. Also, the seemingly singular point that information is the same for both complex and imaginary waves and particles. Reality is not as important as information. That's why imaginary particles can do real world work. Ultimately, we have more information about the universe, and information is power, not just successful science. Mulling over the results of the single slit experiment, we realize these few important points.

The results of a simple misinterpretation, once corrected lead to some interesting results. One will follow from the other in logical order. Just because a matter wave collapses, does not mean the story is over. Since there was a definite probability that the matter wave both makes it through the slit and hits the slit at the same time, no matter what the combination, this probability adds up to 100%. It is more complicated than that, because even if a matter wave collapses at the slit, the portion of the probability that makes it through does not disappear - it just becomes imaginary. It is still there, just not complex any more. This is a P2 Remnant Wave (or just a remnant wave for short) - what's left over from how the universe makes its decisions. Now, wave functions are collapsing all the time, not just in our experiments, but in nature. So natural processes are also making remnant waves - it means the universe is filled with remnant waves.

It's important to still realize that these remnant waves are still waves, and still possess the properties they had while they were still complex - before they collapsed. They are probability waves - nothing in this area has changed. Now what do waves do when they intersect each other? They will add together constructively or destructively. Now, here is an interesting thought. When 2 remnant waves intersect with each other, and they add constructively to 100% what happens? For a time, there exists a 100% probability that there will be a particle at this particular point. We would see a particle appear and then vanish as the waves pass through each other. In fact, when we look at empty space, this is exactly what we really do see - particles appearing and vanishing, coming from nowhere, going to nowhere. This is in fact the energy floor of the universe - the so called Zero Point Energy. Since there is really no energy involved in the creation of these particles, calling them zero point particles is very appropriate. What we are really looking at is not energy at all, but the manifestation of pure probability at work. Probability created those particles, not energy. They don't last long, but while they are here, they can behave as if they were real particles. Imaginary particles can do real work because probability is more 'real' than energy. Remember, the imaginary particle still has the same information it had while it was a complex particle. An imaginary electron behaves the same way it did while it wasn't.

How long can these imaginary particles last? Well, we have something called Heisenberg's Uncertainty Principle which gives a sort of life time based on fundamental quantum constants. The astute reader will also realize some other factors - the angle of incidence between the imaginary waves, and also just what happens if the probability of two or more remnant waves add up to more than 100% . It seems Geometry of a sort is somehow related to Mr. Heisenberg's principle.... Anyway, this is all Academic. We know the two things we need to know to make up a FTL communicator. 1) We can manipulate the complex wave via conventional techniques, which means we can imprint information onto it. And 2) even after wave collapse, the imaginary remnant wave will contain the same information it had while it was still complex.

Also, as I said before, not only do these results offer a more complete phenomenological description of reality, it's important to know just how little they really deviate from accepted theory. Getting this far along, mayhaps your mind is buzzing with probabilities... I wouldn't blame you a bit. But so far most of these ideas are old, perhaps with the single exception of defining P1 and P2, (and the results that arise from separating them). Again, I recommend the Feynman Lectures on Physics. (If you do get the set, make sure it's the Hardbound one - It consists of 3 sturdy books, volume 3 on quantum physics. The paperback may save you a few dollars, but falls apart.) Anyway, I like Feynman not just because he knows his physics, but for his ability to get across the ideas he is talking about - the book has math in it, of course, but even a high school student will gain an understanding because Feynman explains what the equations mean in ways people can understand. It's been my belief that if an author can only speak about Quantum Physics in mathematical terms, he doesn't know what he is talking about - this web site has been 100 times harder for me to put together because of that belief.

Professor Feynman's book(s) were literally transcriptions of lectures he
gave at Caltech way back in 1961 - 1962. In the third volume, on quantum
mechanics, in chapter
21, on the Schrödinger equation, he gives an interesting talk about the
conservation of Probability - almost the same stuff we are talking about:
section 21-2 "The equation of continuity for probabilities". Remember I said
that for both P1 or P2 the wave equation will always add up to 100%... this is
the same as saying probability is conserved. Well, Feynman talks about how
probability is conserved in a local sense. If something interferes with the
probability of finding an electron at one place, say by lowering it, then the
probability of finding it somewhere else will increase, or vice versa. He was,
back in 1962, talking about local probability. Although non local physics was
known about in those years, there was no experimental proof: it could be
nothing more than a mathematical fantasy - and math is __not__ physics.
Feynman said that the mere conservation of probability was not enough to satisfy
the requirements of the wave equation. He was also concerned with the *
flow *of probability. He likened this flow to a current of probability in
much the same way that there is a flow of electrical current for voltage. He called this
quantity *J. *He then went on to show how *J *is real and
defines what it meant for this current of probability, *J* , to be
locally conserved.

**But, what about non-local conservation of J ?
This would involve an imaginary probability current ( **
