For all intents and purposes, it is safe to assume that the universe is infinite in spatial extent, without edge or strange connectedness.

A vacuum consists of a minimum of two things.
1. A empty space.
2. Matter.
A empty space is not a vacuum, but a neutral space. Only when matter appears inside this space does a vacuum force appear. A vacuum is compared to a atmosphere of pressure "1 bar". There are a few ways to measure a vacuum and to determine its purity. The purer the volume of space is the closer it is to absolute zero pressure. In other words neutral. The less matter there is inside this volume of space the closer to absolute neutral the volume of space is. That is what vacuum is all about.
If a empty space is always neutral. It must be the matter that exists within that neutral space we measure negative vacuum force of.

It's confirmed: Matter is merely vacuum fluctuations
Any thoughts?
Fancy worded title. Completely misleading. The big thing here is they have found a way to make QCD calculations almost as easy as QED, which will have thousands of tech applications.
As for the virtual fermions(quarks) and virtual bosons (gluons) that they said make up most of our mass, this is already the standard picture. These virtual particle pairs are constantly going in and out of existence at a stupid fast rate, giving them the appearce of solid mass.
the last paragraph about the higgs contributing a small amount to mass, thats retarded casue virtual particles, if they had mass would get it from interacting with the higgs field too.
They are entering and exiting reality as we understand it, that does not mean that they are exiting reality.
Any thoughts?
No you got the wrong picture.
And im not patient enough to go through all the steps to make sense of virtual particle pairs.
Up and down quarks are the lightest of the possible six flavors of quarks that appear to exist in the universe. In addition to the proton's three resident quarks, the peculiar rules of quantum mechanics allow other particles to appear from time to time. These ghostly particles usually vanish in a tiny fraction of a second, but it's possible that they stay around long enough to influence the structure of the proton. Nuclear physicists set out to catch some of these ghostly particles in the act. They determined that the nextlightest quark, the "strange" quark, would be the most likely to have a visible effect.
According to Doug Beck, a professor of physics at the University of Illinois at Urbana-Champaign and the spokesperson for the G-Zero collaboration, one way to see these strange quarks is to measure them through the weak interaction. "If we look with photons via the electromagnetic interaction, we see quarks inside the proton. And then, if we do it with the weak interaction, we see a very similar, yet distinctly different view of the quarks. And it's by comparing those pictures that we can get at the strange quark contribution," Beck says.

Actually....

Do you think the vacuum the material universe resides in/is of... is infinitely "large",,is all that has always existed,, in the format that "what exists must exist in" ,,,
In an Infinitely large area of vacuum.. what caused our relatively massive universe to exist in a specific portion of the infinite vacuum? how did so much more then quantum fluctuations .. appear,, and continue to appear.?

Hard questions.
There isn't an answer for that yet. As far as we know you cant have a vaccum without space, cause thats what a vaccum is, space in its lowest energy form. Basically the closest you can get to "no action"

These quantum fluctuations interact with matter, and they are functional to its structure. The Universe is an object that as a whole, has a mass, where invariably separateness is not really the issue (EPR Paradox).
Not all quantum fluctuations are non-random. If that were the case, matter as we understand, it would be missing a component to its structure. The Universe is expanding into space-time, the matter inside of it with sufficient mass to fold some space-time around it, space-time being a substance/fabric. Which explains why quantum fluctuation can occur.
The virtual quark has to go somewhere......
Any thoughts?

No space/time is expanding. not the universe is expanding into space time.
As for the clown shoes, Im done talking to you. You didnt say how I was wrong, you just ramble. I
(b) If the universe is finite, the expansion just described increases the overall size of the universe. However, a more useful marker of the expansion is to consider any two objects, say galaxies, that are being driven apart by the expansion of space. You can think of them like two poppy seeds in a muffin that’s being cooked and as the dough expands, the poppy seeds move apart from one another. In this way of thinking, the expansion of space is reflected in the distance between two such galaxies growing larger and larger over time. And that characterization of the expansion holds true whether the universe is finite or infinite. So, when we speak of space expanding we mean that the distance between objects in space increases over time, even if there isn’t a useful sense in which the overall size of space is growing (as would be the case for an infinite universe).
