Does quantum field fills every single piece of the universe?

In summary, the article discusses how the mass of particles comes from the interaction of particles with a field, and how vacuum fluctuations don't make sense if regions of the universe have less of a field. Additionally, the article mentions that the weight of a person comes mostly from borrowed energy, and that the quarks that make up an individual's atomic nucleus weigh almost nothing.

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:).

FAQ: Does quantum field fills every single piece of the universe?

1. What is the quantum field theory?

The quantum field theory is a theoretical framework that combines quantum mechanics and special relativity to describe the behavior of subatomic particles. It states that all particles are actually excitations of underlying quantum fields.

2. How does the quantum field theory explain the filling of the universe?

The quantum field theory explains that the universe is filled with numerous quantum fields, each corresponding to a different type of particle. These fields are present everywhere in the universe, even in empty space, and interact with each other to give rise to the particles we observe.

3. Does the quantum field theory apply to all types of particles?

Yes, the quantum field theory applies to all types of particles, including matter particles (such as electrons and quarks) and force-carrying particles (such as photons and gluons). It also applies to particles that have yet to be discovered or fully understood.

4. How is the quantum field theory different from classical field theories?

Classical field theories, such as electromagnetism and general relativity, describe the behavior of particles as continuous waves in space and time. In contrast, the quantum field theory describes particles as discrete excitations of underlying quantum fields. It also incorporates the principles of quantum mechanics, which have no equivalent in classical physics.

5. Is the quantum field theory a complete description of the universe?

No, the quantum field theory is not a complete description of the universe. While it successfully explains the behavior of particles at the subatomic level, it does not yet account for the effects of gravity. Scientists are still working on developing a theory that combines the principles of quantum mechanics and general relativity to provide a complete understanding of the universe.
