For the heck of it - I will clear up a few things, just in case there are an lurkers:
"And we would probably disagree with the definition of nothing. The particles that physicists observe springing forth come from a vacuum consisting of three spatial dimensions and a fourth dimension called time with energy present. This is certainly not nothing. True nothingness is a void not comprehendible to human cognizance."
Elementary particles do not according to the Standard Model have volume, so they do not have 3 spatial dimensions. Nor does it even make sense to say that particle has a temporal dimension - it may exist in a temporal dimension, but it is not a quality of the particle itself.
Many people like to think of particles as little "balls" - this is a useful analog sometimes, but it not really that close to what they really are. Problem is that they are so alien to human experience that words on't exist to truly describe them. Best I can do is to call them wholes in the vacuum.
"JEP: Kind of agreed, but only from my soap box. I believe our main contention on virtual particles might be their cause and origin. Some particle physicists would have us believe that these particles are springing from nothing. They just seem to poof into and out of, existence. But I dont believe this to be true. Hawking states that these particles spring from energy. "
You are misrepresenting Hawking here, but not intentionally - it just gets confusing. Virtual particles spring from fluctuations of the local vacuum energy which is best described a rolling sea of potentials (both positive and negative). The Vacuum energy, however, sums to zero - meaning that a spike in one place of positive energy has a corresponding (or several lesser) spike of negative energy. Thus, there is still zero energy causing particles to spring into existence. Of course, these particles exist within the boundraries of uncertainty - so they themselves never truly "exist," yet their effects do.
