No I don't assume anything and not it isn't crumbling. It's cause experiments show the bosons to exist as predicted.
You keep saying reality is virtual in nature. I've shown you that virtual particles doesn't mean what you think it means so it most certainly doesn't mean immaterial or nothingness. Things that can be measured are said to be real, are said to exist. I feel like that's so fundamental I can't understand having to even say it.
All these particles are points, localized vibrations, in a field. It is the field that is all important. The 'particle' cannot exist without the field. Anyway, I'm going with the following description:
"Physicists now use a class of theories called quantum field theories, or QFTs, which were first postulated in the late 1920s and developed over the following decades. QFTs are intriguing, but they take some getting used to. To start, let’s think only about electrons. Everywhere in the universe there is a field called the electron field. A physical electron isn’t the field, but rather a localized vibration in the field. In fact, every electron in the universe is a similar localized vibration of that single field.
Electrons aren’t the only particles to consist of localized vibrations of a field; all particles do. There is a photon field, an up quark field, a gluon field, a muon field; indeed there is a field for every known particle.
And, for all of them, the thing that we visualize as a particle is just a localized vibration of that field. Even the recently discovered Higgs boson is like this. The Higgs field interacts with particles and gives them their mass, but it is hard to observe this field directly. Instead, we supply energy to the field in particle collisions and cause it to vibrate. When we say “we’ve discovered the Higgs boson,” you should think “we’ve caused the Higgs field to vibrate and observed the vibrations.”

A rather poor analogy, I am sure, would be the refresh rate of PC monitors, which constantly creates and maintains the image on the screen, making it appear as if it were a single static image.
The assumption that we live in a material world was in place before Quantum Physics found issues with that idea. But the assumption was carried forward and still persists.
The same is true of The Laws, which were inherited from Judeo-Christianity. Science simply dropped the idea of a Law-Maker, and kept the laws. But perhaps these so called 'laws' are more patterns than laws.
