Here’s a possible story which helps demystify quantum field theory. A personal visualization, which stays within the bounds of spacetime and avoids needless paradoxes [1].

There are two key concepts to my sketch:

- The first is the Grid, as characterized by Frank Wilczek.
- The second is a quantum’s tail.

The Grid defines a cosmic **superconducting landscape** in which quanta can extend in spacetime essentially without limit, without loss of energy or waveform integrity, unless they interact with or are confined by other quanta within fields.

A quantum’s indefinite tail provides a **context for superposition and entanglement**. So-called waveform collapse and distant correlation of quantum state.

Yes, there are issues as to the viability of these two concepts. Later I’ll try to summarize any commentary that I’ve found so far.

This post lays out the first idea, namely, the Grid.

### The Grid

The Grid [that ur-stuff that underlies physical reality] fills space and time. Every fragment of Grid – each space-time element – has the same basic properties as every other fragment. The Grid is alive with quantum activity. Quantum activity has special characteristics. It is spontaneous and unpredictable. And to observe quantum activity, you must disturb it. The Grid also contains enduring, material components. The cosmos is a multilayered, multicolored superconductor. The Grid contains a metric field that gives space-time rigidity and causes gravity. The Grid weighs, with a universal density. – Wilczek, Frank. The Lightness of Being: Mass, Ether, and the Unification of Forces (p. 111). Basic Books. Kindle Edition.

#### Grid analogy

A grid is often used to describe how various things are distributed in space. b. The Grid, which underlies our most successful world-model, … – Wilczek, Frank. The Lightness of Being: Mass, Ether, and the Unification of Forces (p. 74). Basic Books. Kindle Edition.

One of the best analogies for Wilczek’s Grid (which he uses himself, as noted above) is a Geographic Information System’s **multilayered data model**, as discussed in this article:

#### The Grid as superconductor

Thus we come to suspect that the entity we call

empty space is an exotic kind of superconductor. – Ibid. p. 96.Even though the conceptual and mathematical parallels run very deep,

Grid superconductivity differs from conventional superconductivityin four main ways: … – Ibid. p. 213.

#### The Grid as multilayered

The primary ingredient of reality is alive with quantum activity. … The primary ingredient of reality also contains enduring material components. These make

the cosmos a multilayered, multicolored superconductor.I will use the word Grid for the

primary world-stuff. That word has several advantages [vs. ether, space-time, quantum field]:We’re accustomed to using mathematical grids to position layers of structure, … – Ibid. p. 74.

#### Ordinary matter = Grid excitation

Ordinary matter is a secondary manifestation of the Grid, tracing its level of excitation. – Ibid. p. 75. [2]

So the recent astronomical discovery that Grid weighs – that the entity we perceive as

empty space has a universal, nonzero density– crowns the case for its physical reality. – Ibid. pp. 104-105.

#### Visualizing the Grid

We’ve seen that not only can two quanta be entangled with each other, but

a single quantum can be entangled with the quantum vacuum.– Hobson, Art. Tales of the Quantum: Understanding Physics’ Most Fundamental Theory (p. 181). Oxford University Press. Kindle Edition.

#### Grid dynamics analogy (shear)

**Objective**: Visualize layered Grid interplay with spacetime geometry, within context of stress–energy–momentum tensor in relativity theory.

Layered (stratified) systems are common in fluid dynamics, e.g., for plasma, gas, water. Macroscopic stellar and planetary atmospheres, oceans. Where there are gradients, due to density, temperature, …

As a physical model, stratification introduces the notion of **shear** (stress) between layers. And perhaps conceptually as quantum **curvature** and inertia. [3]

### Notes

[1] As a counterpoint to statements like this:

• New Scientist > “How quantum entanglement really works and why we accept its weirdness” by Michael Brooks (22 May 2024) – Subatomic particles can appear to instantly influence one another, no matter how far apart they are. These days, that isn’t a source of mystery – it’s a fact of the universe and a resource for new technologies

“

These quantum correlations seem to appear somehow from outside space-time, in the sense that there is no story in space and time that explains them,” says Nicolas Gisin at the University of Geneva, Switzerland.

[2] Here’s a quote from one of Wilczek anecdotes about Feynman.

Feynman told me that when he realized that his theory of photons and electrons is mathematically equivalent to the usual theory, it crushed his deepest hopes. He had hoped that by formulating his theory directly in terms of paths of particles in space-time – Feynman graphs –

he would avoid the field concept and construct something essentially new. For a while, he thought he had. – Wilczek, Frank. The Lightness of Being: Mass, Ether, and the Unification of Forces (p. 84). Basic Books. Kindle Edition.

[3] Here’s an article about research on “**the shape of space-time surrounding a proton**” – **twisting shear forces and pressure changes**. Which someday might explain “*why quarks bind themselves into protons at all*.”

• Quanta Magazine > “Swirling Forces, Crushing Pressures Measured in the Proton” by Charlie Wood (March 14, 2024) – New experiments – exploring the distribution of subatomic energies, forces and pressures – show [shear] forces push one way near the proton’s center and the opposite way near its surface.

Over decades, researchers have meticulously mapped out the electromagnetic influence of the positively charged particle. But in the new research, the Jefferson Lab physicists are instead mapping the proton’s gravitational influence — namely, the distribution of energies, pressures and shear stresses throughout, which bend the space-time fabric in and around the particle.

Schweitzer [Peter Schweitzer, a theoretical physicist at the University of Connecticut] has spent most of his career thinking about the gravitational side of the proton. Specifically, he’s interested in a matrix of properties of the proton called the

energy-momentum tensor. “The energy-momentum tensor knows everything there is to be known about the particle,” he said.

The new approach measures the region of space-time that’s significantly curved by the proton.But protons are made from the lightest members of the quark family. And lightweight quarks can also be thought of as lengthy waves extending beyond the proton’s surface. This picture suggests that the binding of the proton may come about not through the internal pulling of elastic bands but through some external interaction between these wavy, drawn-out quarks.
