I simply had nothing new to add myself. I did not think I could add 
anything that might help you understand each others point. I was clear 
to me that everybody seemed intent to stick to their own 
(mis)interpretation. So why bother?

Huh. I thought it was going. I learned a fair amount from it myself, at 
least.

Thank you for explaining.  I sincerely appreciate you telling me what 
I'm doing wrong.  Thanks!

Umm, yeah. Kind of figured that is what science is supposed to do right? 
lol But, I think it scales well anyway. If an electron is passing 
through a wire, some "escapes" when it gets near the edge, otherwise it 
has constraints on "where" it can show up. Since that can't be in the 
middle of an existing particle, and other forces seem to deny it 
appearing "too close to" another one, its only real option is to shove 
something out of the way, or stay where it is (more or less). Which one 
it does depends on the level of stability inherent in the other 
particles around it, and the forces thus being applied to it. In that 
sense you obviously "can" narrow its allowed area of fluctuation, and 
increase it by firing it through less dense materials.

Well, I suppose its more like what I describe above. Your right though, 
I over extended it a tad. lol

Or, maybe not. If you have a vacuum, one of the properties of that 
vacuum is that there are no other particles to "force" any particles 
left in it to "stay" within the "normal" space they occupy. So, maybe 
they are not "virtual" so much as, existing, but with an increased range 
of "wobble" that is now in meters, instead of millimeters? The 
assumption has always been that virtual particles are not "real" in the 
same sense as normal ones, but what if they already exist, just the lack 
of material density lets some existing particles "drift", at least 
temporarilly, outside the bounds that their normal constraints would 
allow? Not sure how the heck you would test that though. Look for 
virtual electrons while simultaneously looking at every object for 5 
feet in all directions to see if it "temporarilly" lost one?

My emphasis was on "one experiment". There have been hundreds of 
unintuitive results from experiments. Trying to explain just one, when 
it contradicts a bunch of others, isn't likely to be too productive. 
Fun, perhaps, but unproductive. :-)

It has very few constraints, really. There are very few conditions where 
probability is actually zero.

Actually, it can, depending on the polarization.

I don't know what you mean. Vacuum is full of other particles, and I'm 
not sure what "normal space" would be.

I wasn't aware of that.

In any case, I can't follow what you're talking about. It's either too 
far from the terms that everyone else uses, or too vague for me to have 
any idea what you're trying to say.

I mean real in the sense that they "stay put", instead of vanishing 
again. You know, like a "virtual" thing that isn't always there? I 
presume that is what they mean, otherwise you wouldn't have a vacuum 
very long, particles would keep popping into it until it was full again. 
So, one alternative to the idea that they *are* virtual, is that they 
are in fact not popping into existence at all, they already "do" exist, 
but that its the absence of a lot of, comparitively, dense materials 
that allows "existing" particles to sometimes "show up", with a greater 
odds of doing so, in the vacuum. However, since there is also nothing to 
stabilize them in that location, they "pop" back to their original range 
soon after, since there is nothing to keep them in the vacuum and the 
attraction of the other particles where they where before is greater. 
Sort of the opposite of dispersion you see with most things. Instead of 
being attracted to places that 'do not' contain the substance, like with 
osmosis, in this case, the lack of anything to attract them means they 
can't stay there, even if they do occasionally "jump" into the empty 
area very briefly.

But, just speculating. After all, the point, if you have one experiment 
that doesn't make sense, and you can't resolve the difference, is to try 
to unify the results, and that "may" mean reconsidering your assumptions 
about what particles "appear" to do normally, rather than presuming that 
you have just found some odd special case.

According to the math, they don't "stay put". Virtual particles are 
created when a "real" particle vanishes. Then the virtual particles bump 
into each other again and turn back into the "real" particle.

Sure. Or do more experiments to figure it out.

Actually, this just out...

It's a lack of reality, and not a lack of non-local interactions, 
according to these guys. :-)

Not *quite* what I was getting at, in that my suggestion would, by this 
logic, imply that some particle in a solid object nearby vanished, 
generated two virtual particles, bumped into each other to make a real 
one again, which you could detect in the vacuum, or, if unmolested, 
vanished into two virtual ones again, just to "pop" back into being 
inside the solid object where they started from. That would be actually 
*more* disturbing than what I implied as a solution. lol

Yep. That's pretty much what can happen.
