The Vacuum Where the Evidence Should Be

Zach Bush, a physician in good standing, sits across from an interviewer and describes the soul, calm and fluent, generous with wonder. He says that every millionth of a second the atoms of your body dissolve and return, that a single fertilized cell organizes itself into a child by reading a map no biologist can locate, and that the map lives in the vacuum, in the electromagnetic field that fills the empty space inside every atom. He calls this the anatomy of the soul. In a 2021 essay on his own website he writes that the body projects itself as a hologram, and that its apparent solidity is an impression made by light. The performance is seductive because the vocabulary is real. Differentiation, migration, electromagnetic field, vacuum: each of those words has a home in a textbook. The trouble begins the moment you check whether they are being used the way the textbooks use them, or whether they have been borrowed to dress an idea that biology and physics both reject.

I want to take the idea seriously enough to test it, because the man saying it is no stranger on a street corner. He trained in internal medicine, endocrinology, and hospice care, and he speaks with the authority that training confers. When a person of that standing tells a large audience that science has no answer, the audience tends to believe him. So the question worth asking is narrow and answerable. Is the anatomy of the soul a description of nature, or a story wearing the costume of one?

A number that means nothing

Begin with his arithmetic, since numbers are the easiest claims to check. He says differentiation, the moment a generic cell commits to becoming a kidney cell or a neuron, arrives around the 260th round of division. The figure collapses under a pocket calculator. Each division doubles the count, so the forty-fifth doubling already yields roughly thirty-five trillion cells, near the size of an adult human body, which is commonly estimated at about thirty-seven trillion. The 260th doubling would produce a number on the order of ten to the seventy-eighth power, comparable to the count of atoms in the observable universe. No body holds that many cells. No process in embryology counts that high. The real sequence is humbler and well charted. Differentiation begins earlier and smaller, with the split between the cells that will form the placenta and the cells that will form the embryo arriving around the fifth or sixth doubling, when fewer than two hundred cells exist. The kidney cell and the neuron he names appear weeks later, during gastrulation and organ formation. His 260 approximates none of this; it is a figure chosen for the sound of precision.

A blueprint he says is missing

The center of his argument is a denial. In a filmed conversation he states it without hedging: inside human DNA there is no blueprint and no information, and so the body must be organizing itself from somewhere outside the cell. In a recorded segment for a health-education series he goes further, telling viewers that any physician, scientist, or regulatory body claiming to understand what happens inside them is simply wrong. This is the load-bearing wall of the whole edifice, and it is false in a way that should embarrass anyone who has opened a developmental biology journal in the last half century.

We have the map. We have held large portions of it for decades, drawn by people whose names are on the work. In 1969 the biologist Lewis Wolpert proposed positional information, the principle that a cell learns where it sits in the body by reading the concentration of signaling molecules around it and behaving accordingly. Those molecules are real and named: Sonic hedgehog, the bone morphogenetic proteins, the Wnt family. A cell bathed in a high concentration becomes one thing, a cell in a low concentration becomes another, and the gradient between them paints a coordinate system across living tissue. Layered above sit the Hox genes, a set of master switches arranged along the chromosome in the same order as the body parts they govern, so that the genome carries a literal head-to-tail address book. We even know what happens when an address is misprinted. A mutation in the fruit fly gene Antennapedia causes legs to sprout from the head where antennae belong, a grotesque proof that the DNA was carrying spatial instructions all along. In 1995 the Nobel Prize in Physiology or Medicine went to Edward Lewis, Christiane Nüsslein-Volhard, and Eric Wieschaus for uncovering this genetic control of early development. The prize was awarded for finding the map the physician says cannot be found.

To claim that DNA holds no blueprint is to wave away that entire enterprise, the experiments, the mutant flies bred across generations, the award in Stockholm. The honest statement is less convenient for a tidy soul. The map is real, it is part chemical and part mechanical and part electrical, and it is incomplete. Biologists argue among themselves over whether the word blueprint even fits, since a genome works more like a recipe whose outcome depends on conditions than like a fixed architectural drawing, yet that quarrel concerns the precision of a metaphor and has no bearing on his far larger claim that the cell holds no information at all, which the genetic code refutes on its own. Open questions survive about how patterning holds its accuracy when an embryo is cut in half and still grows a whole animal, or how the same instructions scale from a mouse to a whale. An incomplete map is a standing invitation to the next experiment. It grants no one the right to declare the territory unknowable and move the answer into the vacuum.

The two fields he welds together

Here the argument performs its cleverest move, because it stands beside a real and surprising science before walking past it. There is a documented field called bioelectricity. At Tufts University the biologist Michael Levin has shown that patterns of voltage across cell membranes carry anatomical instructions, that rewriting those electrical patterns can prompt a frog embryo to grow an eye where no eye belongs, or push a flatworm to regenerate a head it was never cut to grow. Recent work models the developing body as coupled electrical and mechanical fields that steer its growth. All of this is peer-reviewed, repeatable, and strange enough to feed any hunger for mystery. All of it is also, in every particular, biology. The voltages come from living cells pumping charged atoms across their membranes, powered by the same metabolism that runs your muscles. They have nothing to do with the quantum vacuum, with zero-point energy, or with the empty space inside an atom.

The physician fuses the two anyway. He takes the word field from cell biology, where it names voltage maintained by ion channels, and the word vacuum from physics, where it names the lowest energy state of empty space, and he welds them into one glowing object that lives in neither discipline. The quantum vacuum is genuine. Its fluctuations have been measured in the laboratory at the femtosecond scale, a millionth of a billionth of a second. It does not reach into your abdomen and instruct a cell to become a kidney. Bioelectricity does some of that instructing, and it does so with chemistry you could read off an electrode. Calling both by the same mystical word hides the seam between them without ever joining the two.

The body that supposedly blinks

Then comes the image that lodges in the memory and travels furthest, the claim that you dissolve and reappear about a million times a second. He has put it in print and repeated it aloud: every millionth of a second the atomic structure of the body dissolves and returns. No physics supports this. The fastest relevant process in the same vacuum he invokes, the flicker of the electromagnetic field, runs at the femtosecond scale, nine orders of magnitude faster than his figure, which leaves his clock wrong by a factor of a billion. Nerve signals run on milliseconds. Molecular vibrations run on femtoseconds. Nothing in the body resets your identity a million times a second, because nothing resets it on a fixed clock at all. The number wears the costume of a measurement while measuring nothing, and its only office is to make a poem feel like a readout.

He extends the same picture to death. On his website he writes that when a body dies its energy is not destroyed and simply moves back into the vacuum of the universe. The first half of that sentence states a law of physics, since energy is conserved. Its second half is a sleight. The energy in a living body sits mostly in chemical bonds and body heat, and at death it disperses, warmth leaking into the room and matter feeding decomposition, the joules conserved to the last and the arrangement that held them gone. The law that governs the fate of the pattern is entropy, and entropy guarantees that the structure which was you scatters and never reassembles. A burning candle conserves its energy down to the last joule, and no one waits for the flame to gather itself back out of the warm air. Conservation of energy was only ever a promise about joules, and a dispersing body keeps that promise in full while keeping nothing of the person.

The damage

A reader of generous temper will object that the man is speaking poetically, reaching for awe, and that picking apart his arithmetic misses the spirit of the thing. I would welcome that defense if he offered the words as poetry. He does not. The interviews and the essays insist on the reverse. One published account of his worldview presents the claims as literal biology and refuses any reading of them as metaphor. He presents the dissolving body and the missing blueprint as established findings, and he wraps them in the credibility of a medical license. That is where the harm enters.

Two reactions are easy to anticipate and easy to grant. A man may find the universe beautiful, and it is. He may suspect that something survives us, and no laboratory can refute him. The harm sits elsewhere, in a single instruction he has given his audiences: that every physician, scientist, and regulatory body claiming to understand your body is wrong, and that you should trust the awe he is offering instead. Consider what that does to a frightened person holding a real diagnosis. It teaches them that the oncologist consulting the evidence is no more reliable than the speaker consulting the vacuum. It converts the honest scientist’s admission that some questions remain open into a license to believe anything at all. When a physician tells the public that medicine knows nothing, he strips away their means of telling a tested claim from an invented one, precisely when they need that skill most.

The same move powers a large industry. Declare the experts blind, cast yourself as the rare seer who perceives the hidden field, and the audience that follows you out of the clinic has nowhere left to place its trust except in you and in whatever you are offering, whether a supplement, a program, or a worldview. The physician in question built an advocacy organization around fear of a single agricultural chemical, and he speaks across a commercial platform that rests on the authority of his coat. None of this requires bad faith on his part. Sincerity and damage share a bed without difficulty. A person can believe every word he says and still teach a million listeners that confidence and proof are the same currency.

It is worth asking who keeps showing up for this, and why they sit within his reach. His audience is rarely careless. It is largely made of people whom medicine has helped and failed in the same breath, the chronically ill, the frightened, the ones handed a prognosis without a sentence of comfort and sent home to sit with it alone. Modern medicine treats the body well and the meaning of the body hardly at all. It will name the tumor and book the operation and fall silent on the questions a patient lies awake holding, why this is happening, what they are, whether any of it matters. Bush steps into that quiet and tells them their body is a luminous intelligence, a marvel past any machine, present here by its own choosing. What he says is unproven and the relief it brings is real, and a person in pain will reach for real relief even when it is fastened to a false fact. That is the hunger he feeds, and what he draws from feeding it is plain enough, the reverence owed to a healer and the income of a thriving brand. He hands them back a feeling of significance and awe, and he charges for it in the trust they can no longer spend on the doctors who could still save them.

The thing that is actually true

What stings most about the anatomy of the soul is that the real story dwarfs the counterfeit. A single cell does build a precise, three-dimensional animal, and it does so by reading a coordinate system written in chemistry, electricity, and force. Its genome carries an address book that sets the spine ahead of the tailbone. Cells migrate across measurable distances to reach the right organ, steering by signals an electrode can detect. The voltages that pattern an embryo can grow an eye in the wrong place when an experimenter rewrites them. All of it is documented, all of it astonishing, and none of it needs a vacuum to be complete. It loses nothing by being checkable.

The soul, if there is one, sits beyond the reach of an electrode, and an honest physician can say so without dressing the silence in borrowed physics. My objection to this man’s teaching has nothing to do with his speaking of the soul. It concerns what he does next: he assigns the soul an anatomy, gives that anatomy false coordinates, and signs the diagnosis with a medical license. A claim offered as science carries obligations. It must be dated and sourced, and built so that evidence could in principle prove it wrong. His meets none of those tests, which is why it does not qualify as science, whatever the white coat implies. Wonder is free to anyone who wants it. The authority of evidence has to be earned one checkable claim at a time, and it can be spent only once before the people who trusted it discover they were paying for a hologram.
