Have you ever met someone who claims to have solved the entire universe? We have, and we took the claim seriously enough to test it. Welcome back to FreeAstroScience, dear reader; whether you are a lifelong physics fan or simply curious about big ideas, you belong here. Today we examine The Modest Theory, a self-published model that calls the cosmos a fractal and gravity a pressure gradient. Its author is a software engineer, so we borrowed his own professional language and ran a full debugging session on the idea. Stay with us to the end, and you will leave with a tester toolkit you can point at any theory of everything that lands in your feed.
TL;DR — The Direct Answer: The Modest Theory claims the universe is one repeating fractal and gravity is a pressure gradient. Observations disagree: galaxy surveys show the cosmos becomes statistically homogeneous above roughly 100 to 300 megaparsecs, and pressure-based gravity models fail the precision tests that general relativity passes. With no equations and no testable predictions, the idea remains a metaphor rather than a working theory.
The fractal universe theory has a long and respectable history in cosmology, stretching from 18th-century hierarchical models to modern galaxy surveys. The Modest Theory is its newest and boldest descendant, and it makes three central claims we can put on the test bench: mass is a loop of energy, gravity is a pressure gradient around that loop, and one self-similar pattern runs through everything from particles to superclusters.
What Does The Modest Theory Actually Claim?
The Modest Theory claims that mass is a loop of energy, that gravity forms around the loop as a pressure gradient, and that the whole universe repeats one fractal pattern across every scale. Its author, James Hutchison, is a computer scientist and software engineer with about two decades of industry experience. He published the theory and a series of addenda on Medium between 2025 and 2026, together with a simulator on his website.
The name is a deliberate joke. Hutchison calls it a theory of everything, but not the Theory of Everything, and he describes it as intentionally incomplete. He is candid about the vagueness: he admits the fractal is a fuzzy idea that is hard to nail down, one he compares to a crime scene full of evidence that always allows alternative explanations. At the same time, his confidence is total:
I’m 100% certain this is how things work. There is no doubt.
That combination is worth pausing on. A model with no fixed mechanics that its author holds with absolute certainty is unusual in science, where confidence normally grows out of surviving tests, not preceding them. We will come back to this point, since it turns out to be the deepest bug of all. First, let us be fair to the strongest part of the idea: the fractal itself.
Is the Fractal Universe Theory Supported by Evidence?
Only up to a point: galaxy clustering really does look fractal below roughly 100 megaparsecs, but the pattern dissolves into smoothness at larger scales. That distinction is the difference between a fascinating property of cosmic structure and a claim about the whole universe.
The idea itself is old and honorable. Hierarchical universes appear in the 18th-century writings of Swedenborg, Kant, and Lambert. In 1922, the Swedish astronomer Carl Charlier built a formal model in which clusters of galaxies nest inside ever larger clusters without end. Benoit Mandelbrot gave the pattern its modern name, fractal, in the 1970s, and statistical studies of galaxy catalogs later measured a fractal dimension between 1.5 and 2 on scales below about 100 megaparsecs. Field theorists such as Hector de Vega, Norma Sanchez, and Francoise Combes even showed that gravity itself can generate this self-similar clustering, treating the galaxy distribution as a system near a critical point. Fractal cosmology is still an active research area today, with published models testing scale-invariant alternatives against survey data.
So Hutchison is standing on real ground when he points at self-similar structure. The problem is the extrapolation. Modern surveys, from the Sloan Digital Sky Survey onward, show the galaxy distribution transitions to statistical homogeneity somewhere around 100 to 300 megaparsecs. Above that scale, the universe stops repeating and starts averaging out. The cosmic microwave background makes the same point even more sharply: the early universe was smooth to about one part in 100,000 in every direction we look. A fractal without limit would leave fingerprints on both measurements. Neither shows them.
However beautiful the pattern feels, the data draw a hard boundary around it. A theory built on the claim that the fractal continues through all scales starts its life in conflict with two of the most solid observations in cosmology.
Can Gravity Really Be a Pressure Gradient?
No experiment supports it, and roughly 250 years of attempts show why the idea keeps failing. Push gravity, the family of models in which masses are pressed together by some external medium, goes back to Georges-Louis Le Sage in the mid-1700s. It is intuitive, mechanical, and satisfying. It is also quantitatively broken: any medium dense enough to push planets around also drags on them as they orbit and heats them as it flows past. The drag alone would have spiraled Earth into the Sun long ago. No instrument has ever detected either effect.
Meanwhile, the theory a pressure gradient would need to replace has an intimidating scoreboard. General relativity has passed every precision test thrown at it for over a century:
- Mercury’s orbit precesses an extra 43 arcseconds per century, and Einstein’s equations predicted the number exactly.
- GPS satellite clocks would drift by about 38 microseconds per day without the relativistic corrections engineers build into the system.
- The Hulse-Taylor binary pulsar loses orbital energy at precisely the rate general relativity predicts for gravitational-wave emission.
- LIGO has recorded gravitational waves since 2015, and every signal matches templates computed from Einstein’s equations.
Here is the standard we hold every challenger to, and it is the same one working physicists apply to their own ideas: a replacement for general relativity must reproduce all of these numbers before it earns the right to explain anything new. The Modest Theory computes none of them. It offers the phrase pressure gradient where general relativity offers ten field equations and a century of confirmed predictions. In physics, a phrase is not a competitor.
Where Exactly Does the Theory Break Down?
Every claim fails in a specific, checkable place, so we wrote it up the way the author would: as a bug report. Here is our full ticket list, ranked by severity.
| Bug ID | Claim | What breaks | Severity |
|---|---|---|---|
| BUG-001 | Gravity is a pressure gradient | Push-gravity models predict orbital drag and heating that no instrument has ever detected, while general relativity passes every precision test the model ignores. | Blocker |
| BUG-002 | Mass is a loop of energy | No mechanism keeps the loop stable, and the model predicts no particle masses and no electron g-factor, a number quantum electrodynamics gets right to twelve decimal places. | Blocker |
| BUG-003 | One fractal spans all scales | Galaxy surveys show statistical homogeneity above roughly 100 to 300 megaparsecs, and the cosmic microwave background is smooth to 1 part in 100,000. | Blocker |
| BUG-004 | Total certainty, zero mathematics | The author reports 100% confidence yet supplies no equations, so no experiment could ever fail the theory. A claim that cannot fail sits outside science. | Design flaw |
| BUG-005 | Atoms resemble solar systems, so scales rhyme | The Bohr planetary atom looked right and failed quantitatively; quantum mechanics replaced it. Visual resemblance across scales is not shared mechanics. | Regression |
Notice what the table does not say. It does not say the author is foolish, and it does not say fractals are nonsense. Cosmic structure genuinely shows self-similar clustering on small scales, and spotting patterns is a real cognitive gift. The bugs live in the jump from pattern to mechanism, and in the refusal to let any measurement referee the jump.
What Separates a Scientific Theory from a Beautiful Idea?
One thing above all: a scientific theory tells you, in advance and in numbers, what would prove it wrong. The philosopher Karl Popper called this property falsifiability, and it remains the cleanest boundary line we have. Einstein passed the test spectacularly. He said, in effect: measure light bending around the Sun during an eclipse, and if you get half my number, throw my theory away. The 1919 eclipse expedition got his number, not half of it, and general relativity earned its reputation the hard way.
The Modest Theory inverts this structure. It withholds mechanics on purpose, which means it also withholds every possible point of failure. The physicist Wolfgang Pauli had a famous phrase for ideas built this way: not even wrong. It sounds like an insult, but it is really a category label. A wrong theory has done something useful; it made a prediction sharp enough to be shot down. An unfalsifiable theory never enters the shooting range at all.
There is a second lesson hiding here, and it is one every physics student learns through the Bohr atom. Electrons orbiting a nucleus look exactly like planets orbiting a star, and for about a decade physicists treated the resemblance as a guide. Then measurement after measurement failed, and quantum mechanics revealed a microscopic world running on completely different rules: probability clouds, quantized states, no orbits at all. Resemblance across scales is a hypothesis generator, never evidence. A fractal eye sees rhymes everywhere; an instrument checks whether the rhymes carry weight.
How Can You Debug a Theory of Everything Yourself?
You can test any grand claim in five steps, and none of them requires graduate mathematics. This is the same checklist we ran on The Modest Theory, and it works on every viral theory of everything you will meet online.
- Ask for one number. A real theory computes quantities an instrument can check, such as an orbital precession or a particle mass. No number, no theory.
- Ask what would kill it. If no possible observation could prove the idea wrong, it is not yet science, whatever else it may be.
- Run the regression suite. Any new gravity model must first reproduce Mercury’s precession, GPS clock corrections, binary pulsar decay, and LIGO waveforms. Established results are the tests a new build has to pass.
- Treat certainty as a warning light. Working scientists attach error bars to everything. Total confidence usually signals a missing test, not a finished proof.
- Separate analogy from mechanism. Two systems that look alike, such as atoms and solar systems, can run on entirely different rules. Demand the shared equation, not the shared picture.
Apply these five steps and you will find that most theories of everything fail at step one. That is not cynicism; it is quality control, and it is exactly how physics protects the ideas that do survive.
Conclusion
We opened with a person who is 100% certain he has solved the universe, and we close with a gentler verdict. The Modest Theory gets one thing right: cosmic structure really is fractal-like on scales below about 100 megaparsecs, a fact with a research pedigree running from Charlier to modern survey science. Everything else fails inspection. Gravity as a pressure gradient collides with 250 years of failed push-gravity models and a century of general relativity passing precision tests. Mass as an energy loop predicts nothing that quantum theory has not already measured to a dozen decimal places. And certainty without equations is not strength; it is the absence of a way to lose, which is the absence of science. Our challenge to the author is the same one we offer every bold thinker: give us one number your theory predicts that standard physics does not, and tell us which measurement would kill it. Deliver that, and we will happily write the follow-up.

Frequently Asked Questions
Is the universe really a fractal?
Partly. Galaxy surveys show fractal-like clustering below roughly 100 megaparsecs, with a fractal dimension near 1.5 to 2. Above roughly 100 to 300 megaparsecs, the distribution turns statistically homogeneous, and the cosmic microwave background is smooth to one part in 100,000. An unlimited fractal universe is ruled out by observation.
What is The Modest Theory?
The Modest Theory is a self-published idea by software engineer James Hutchison. It proposes that mass is a loop of energy, that gravity forms as a pressure gradient around that loop, and that the universe repeats a fractal pattern across scales. It offers no equations and no testable predictions so far.
Can gravity be explained as a pressure gradient?
Not with current evidence. Push gravity models date back to Le Sage in the 1700s and fail on measurable grounds: they predict orbital drag and heating we never observe. General relativity, in contrast, matches every precision test to date, from Mercury and GPS clocks to gravitational waves.
What makes a theory of everything scientific?
A scientific theory must make precise, testable predictions that could prove it wrong. It needs mathematics that outputs numbers an experiment can check, such as orbital precession or particle masses. Certainty is not a criterion: a claim that cannot fail any test sits outside science, no matter how elegant it feels.
Who first proposed a fractal universe?
Hierarchical universe ideas go back to Swedenborg, Kant, and Lambert in the 1700s. Astronomer Carl Charlier built a formal model of endless galaxy clustering in 1922, decades before Benoit Mandelbrot coined the word fractal in the 1970s. Modern surveys later limited the idea to scales below a few hundred megaparsecs.
