Yesterday, I read a document published by John Avery that says that “force fields and space are the only things that exist”. He wrote that in a document he shared as a Neo-Epicurean Epitome. It begins as follows:
A Neo-Epicurean Epitome1. Sub-atomic force fields and space are the only things that exist.2. All other things (such as trees, people, and historical events) are temporary attributes of theseforce fields and space. These compound objects have formed over 13.8 billions of years of trialand error in the natural world and one million years in the human world.
After reading that I immediately stopped reading and thought to myself: “An Epicurean has given up on particles when there is no need to do so. Oh no!” The next thought I had was that particle physicist Victor Stenger argues that:
- Quantum Field Theory fields and the particles of the Standard Model of Particle Physics are actually a unity and not at odds. The fields are theoretical parts of the model.
- The Large Hadron Collider detects particles. See for yourself here.
- The phrase “trial and error” of John Avery’s second item fails to explain how the structure of composites arises. It’s sound too random, when in fact forces with deterministic and indeterministic components (an Epicurean swerve) describe the particle motions.
Not being exactly sure of what Victor Stenger wrote, I browsed my copy of his book God and the Atom (Prometheus Books, 2013), the blurb on which says (the bolding is my own):
This history of atomism, from Democritus to the recent discovery of the Higgs boson, chronicles one of the most successful scientific hypotheses ever devised. Originating separately in both ancient Greece and India, the concept of the atom persisted for centuries, despite often running afoul of conventional thinking.
In this book, physicist Victor J. Stenger makes the case that, in the final analysis, atoms and the void are all that exists.
The book begins with the story of the earliest atomists – the ancient Greek philosophers Leucippus, Democritus, and Epicurus, and the Latin poet Lucretius. As the author notes, the idea of elementary particles as the foundation of reality had many opponents throughout history – from Aristotle to …
In conclusion, the author underscores the main point made throughout this work: the total absence of empirical facts and theoretical arguments to support the existence of any component to reality other than atoms and the void can be taken as proof beyond a reasonable doubt that such a component is nowhere to be found.
After reviewing the table of contents of my e-book, I decided to browse some chapters looking for clips to support my thoughts. In what follows, I use clips of Victor Stenger’s God and The Atom to support the idea that modern day Epicureans do not need to give up on the particles of atomism, and to “shout out loudly” that the Standard Model of Particle Physics is our modern day atomism which operates in the modern day space-time of General Relativity. First I start with a quick introduction to Atomism.
Atomism, Ancient and Modern
Epicurus’ Letter to Herodutus says (I’m paraphrasing) that bodies are matter and space, and that matter is composed of elementary particles that: bind (interlace), collide, unbind, and that some very fast particles are also emitted and absorbed as “images”.
It is our Epicurean position that Nature is composed of first bodies, called “elements,” … from them all things in the universe are generated… We Epicureans also maintain that the things that we see are real… The image that we observe in the mirror is proof that particles stream steadily from all things, … These images flow from all objects, and, because they impinge on our eyes, we are able to see external realities, and to have those impressions enter our minds …
And the atoms move continuously for all time, … others swerving, and others recoiling from their collisions. And of the latter, some are borne on, separating to a long distance from one another, while others again recoil and recoil, whenever they chance to be checked by the interlacing with others, or else shut in by atoms interlaced around them.
… these images exist, and that as they move they preserve, in some degree, their respective positions that they held in the solid bodies from which they came. Third, these images move with unsurpassable speed. …
— Epicurus, Letter to Herodotus
Cassius Amicus’ Elemental Epicureanism
…when bodies are carried downward through void by their own weight, at uncertain times and uncertain places they push themselves a little from their course by the slightest of inclinations. If these bodies did not swerve, … But that nothing swerves to any degree case from the straight course, who is there that can perceive? … If first-beginnings do not, by swerving, make some commencement of motion to break through the decrees of fate, … For this reason in first-beginnings too you must admit that besides outside blows and weight there is another cause of motion… Weight alone would require that all things were overmastered and caused by blows from outward forces …The swerve exists; it has always existed; it always will exist.
— Lucretius, On The Nature of Things
Cassius Amicus’ Elemental Epicureanism
The Standard Model of Physics also has elementary particles that bind, collide, and unbind with each other, and these are called fermions (leptons and quarks). The Standard Model also has particles that are emitted and absorbed, these are called bosons.
The bodies of everyday ordinary human life are composites formed by fermions and space. These particles bind with each other to form the chemicals molecules of everyday matter such as wood, steel concrete, stones, plants, animals and human beings.
The particles that stream and form images in our mirrors are known as photons and they move very fast, at the “speed of light”. These photons impinge on our eye’s retina’s photoreceptor cell molecules, causing them to temporarily change shape, which causes an signal (phototransduction) to be sent down nerves to our brain where the signal is processed into perceptions and finally mental impressions. The resolution of our vision is limited by the size and spatial distribution of these photoreceptor cells, the perceptions and impressions are further limited by the brain processing (interpretation).
The observed motion (binding and collisions) of the fermions indicates that they are “forced” away or towards each other in a deterministic way (by the exchange [emission and absorption] of bosons). So the particle motion is not so random (“trial and error”), it has a large deterministic component, and a small indeterministic component to their motion (a swerve).
With the rise of quantum mechanics and the Heisenberg uncertainty principle in the early twentieth century, the “true” randomness inherent in the motion of all bodies became built into the structure of physics. Physicists had (almost) no trouble giving up the determinism of the Newtonian world machine.
Victor J. Stenger, in God and the Atom (Prometheus Books, 2013)
QFT fields and the bosons of the Standard Model of Particle Physics are actually a unity and not at odds. No aspect of reality may contradict another aspect of reality, as that would be a sign of error.
I quote and do not summarize Victor Stenger. Everywhere he writes “quanta” we can substitute “particle”.
The claim that quantum mechanics has revealed a reality beyond matter is based on the mistaken notion that two separate realities exist: discrete, particulate matter and a plenum that is reminiscent of the long-discredited aether. …. You will often see it written that abstract, holistic quantum fields are the deeper reality while particles are simply the excitations of the fields. … Unfortunately, many theoretical physicists have contributed to the impression that quantum mechanics has done away with the concept of matter. …[they] are expressing the Platonic view of reality, commonly held by many theoretical physicists and mathematicians…. The application of Platonic reality to physics is fraught with problems. First, theories are notoriously temporary. We can never know if quantum field theory will someday be replaced … Second, as with all physical theories, quantum field theory is a model— a human invention. We test our models to find out if they work;… If there were an empirical way to determine ultimate reality, it would be physics, not metaphysics. Third, quantum fields all have quanta that we associate with the so-called elementary particles. In relativistic quantum field theory, which is the fundamental mathematical theory of particle physics and the basis of the standard model, each quantum field has an associated particle called the quantum of the field. These are the elementary particles of the standard model. The photon is the quantum of the electromagnetic field. The Higgs boson is the quantum of the Higgs field. The electron is the quantum of the Dirac field. I know of no proven example where a quantum field exists without its quantum. Particles are just as much building blocks of our theories as fields. In fact, they are the same building blocks. There are no exceptions. For every field, we have a particle; for every particle, we have a field. So it is incorrect to think that field and particle exist as separate realities. … We have… a field-particle unity.
Now, those who read the popular literature might have received the impression that, in fact, modern physics has not confirmed the picture of atoms and the void or perhaps even refuted it. … Now, maybe Democritus did not imagine quarks. But he imagined material particles, and quarks are material particles. The “new realm of entities” uncovered in modern physics is hardly beyond imagination. They are imagined in the quantum theory of fields, although just imagining something does not make it real— despite what some theologians claim and what some physicists seem to believe.
Far from demonstrating the existence of a holistic universe in which everything is intimately connected to everything else, relativity and quantum mechanics (and the standard model that was built upon their foundation) confirmed that the universe is reducible to discrete, separated parts. No continuous aether exists throughout the universe. Light is not some vibrating wave in a cosmic medium but is best modeled as a beam of photons streaming through the void. Electricity is not some continuous field moving from place to place but is best modeled as a beam of electrons streaming through the void. (A copper wire is mostly void.)
