The question behind the paper
Think about an old photograph of a distant star. The light in that photograph left the star thousands of years ago. By the time it landed on the film and produced a chemical change — an actual physical mark, something you can touch — the star might not even exist anymore. But the mark is real. It’s a record of something that happened. You can look at it, show it to other people, compare it with other photographs.
Now ask a slightly unusual question: what had to be true about the world for that mark to be possible at all?
Not: what light behaves like, or what the star is made of, or how the chemistry of the film works. Those are all good questions, and physics answers them well. The unusual question is different. It’s about the universe itself: what kind of universe can contain stable marks in the first place? What kind of universe can’t?
Why this is worth asking
Every physics experiment ever performed has relied on the same basic thing: the ability to produce stable, distinguishable records that can be referred back to. A pointer position. A click on a detector. A chemical trace on film. A digital readout. Without records, there is no measurement, no data, no confirmation or refutation of any theory whatsoever.
Physics is very good at describing what happens to records once they exist. It’s far less explicit about what makes records possible in the first place. This is usually fine — we assume the world cooperates, and it does. But if we ask the question seriously, something unexpected happens.
It turns out not every mathematically conceivable universe could produce records. You can write down specific examples of substrates — some of them used every day in physics, as parts of larger theories — which, taken on their own, simply couldn’t support the kind of observations physics requires. A universe whose dynamics ran equally well forwards and backwards, with no way for anything to become permanent, couldn’t hold records. A universe with infinitely fine distinctions between configurations, but no way to turn any of those distinctions into a physical mark, couldn’t either.
The partition is real. Some universes can support observation; some can’t. And if we ask what places a universe on the “can” side of the line, we find something surprising: the answer isn’t empty. There’s structure there.
Facts as physical events
The paper turns on a specific idea: what we call a commitment event. A commitment event is a moment when something that could have gone one way or another actually becomes fixed. The click of a Geiger counter. The emission of a photon. The moment a quantum system stops being “both” and becomes “this, definitely.”
What’s distinctive about our framework is that it treats commitment events as physical things in their own right — not as epistemic labels we attach to processes, but as elements that actively shape what happens next. When a commitment event occurs, it doesn’t just record the universe; it changes it. The past isn’t a story we tell. It’s a set of actual marks that influence the future.
This is more radical than it might sound. In most physics, reversibility is the default. The equations of motion run just as well backwards as forwards. Irreversibility is usually treated as a statistical illusion, something that emerges from averaging over many tiny reversible processes. Our framework takes a different view: irreversibility is fundamental, and records don’t just describe the world — they participate in it.
You can see the intuition without any equations. A clock works because each tick leaves a permanent trace. An atomic clock counts transitions between energy levels of a caesium atom; the count is physically meaningful only because each transition stays put. Run the process in reverse and the clock doesn’t work backwards — it doesn’t work at all. The thing we call time, in any working clock anywhere, is the accumulation of irreversible commitments. We’re asking what happens if we take that observation seriously.
What this buys us
If you take this idea seriously and follow where it leads, something remarkable happens. The framework ends up predicting specific numbers. The fine-structure constant — the strength of the electromagnetic force, about 1/137 — comes out of the geometry, rather than being put in by hand. The ratio of gravitational waves to density fluctuations in the early universe is predicted to sit within a specific, narrow range. Certain enzyme reactions are predicted to show a specific signature. None of these numbers are fitted. They come out of the structure of what’s required for records to exist.
Some of these predictions can be tested now. One in particular — concerning cosmological measurements the BICEP Array telescope is currently making — could falsify the framework outright in the next few years. That’s unusual for a foundations-of-physics paper, and it’s deliberate. We’ve written the paper so that if we’re wrong, we can be shown to be wrong. Cleanly, and without hedging.
Why the paper has two parts
The paper is organised in a way that lets it be read at two levels.
The first part makes a general argument that doesn’t commit to any specific framework: that treating the preconditions for observation as constraints (rather than assumptions) is a productive way to do foundational physics. A reader who agrees with the first part but disagrees with the second part hasn’t lost anything; the general argument stands on its own.
The second part presents our specific proposal — the Void Energy-Regulated Space Framework, VERSF — as one substantive way of pursuing that approach. It has specific axioms, specific predictions, and specific places where it could fail. It’s written in a question-and-response format because a programme of this scope attracts many different kinds of objection, and working through them systematically is more useful than presenting a single linear argument and hoping for the best.
Where this fits in the broader picture
VERSF isn’t the only substrate-level approach in the foundations of physics. It shares commitments with older programmes by John Wheeler, Wojciech Zurek, Carlo Rovelli, Lucien Hardy, and others — all of whom, in different ways, have asked what physical structure follows from the operational preconditions of observation. What distinguishes our approach is a specific move: treating commitment as a physical source, something that enters the equations of motion rather than riding on top of them. Whether that move is right is an empirical question, and the paper is explicit about what evidence would settle it.
For anyone interested in the deeper structure of physics — why the world is the way it is rather than simply how it behaves — this is the kind of work we think is worth doing. It isn’t meant to replace anything. It’s meant to ask whether the foundations we usually take for granted have more to tell us than we usually listen for.
The full paper is available on the VERSF site. We welcome engagement, pushback, and especially the kinds of questions that show us where we’ve gone wrong.
