Does quantum field fills every single piece of the universe?

I mean I read there is no such thing as absolute nothingness (which is logical), you can't create something from nothing.
But does it mean that quantum field fills every single piece of the universe which means there are not "holes", actually in quantum field that are completely empty?
Big thanks for the answer.

I think what people often write, there is a probability of some quantum activity happening throughout the universe.

Eg. Pair creation and annihilation. This happens on a bed of quantum fields rather than coming from a |0> state.

Though, I have no real guess as to what happens inside a black hole

Wow! You're lucky that the notion that there is no such thing as absolute nothingness is logical to you! :D
To answer your question, I'm pretty sure the answer is yes. Referring to this article,
http://physics.about.com/od/quantumphysics/f/HiggsField.htm, I quote

"He proposed that this field existed throughout all of space and that particles gained their mass by interacting with it."

Also vacuum fluctuations don't make sense if there are regions where the fields are 'restricted' from.

Ok, big thanks for the link.

Well, nothing is a tricky term in QM and Lawrence Krauss does not entirely agree:

Depends what you mean by “fills” and “holes”... it’s like a “bubbling brew” of virtual particles, popping in and out of existence, so fast that you can never detect them, hence empty space is not completely empty. The fact is; the weight of your body comes mostly from the “borrowed energy” of virtual particles because the quarks (the building blocks of protons and neutrons in the atomic nuclei) weigh almost nothing (maybe a perfect ‘remedy’ for overweight people – “It’s only virtual!” :smile:).

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
