Why a Universe with “Facts” Can’t Be Arbitrary
One of the deepest questions in physics is this: why does the universe follow the strange rules of quantum mechanics at all? Why not some completely different system of rules?
In the VERSF framework, we take a different approach. Instead of starting with equations and asking if they match reality, we start with something much simpler:
A universe must be able to produce real, definite outcomes — what we call “facts.”
A fact is something that actually happens. A particle is detected here, not there. A coin lands heads, not still spinning forever between heads and tails. If nothing ever settles into a definite outcome, then nothing is ever truly real — and that wouldn’t be a universe we could observe or live in.
What This Paper Shows
This paper takes that simple idea — that facts must exist — and pushes it further. It asks:
What rules must any universe follow if it is capable of producing real facts?
Two important answers come out of this.
1. No Hidden “Behind-the-Scenes” Differences
If two situations look exactly the same in every way that could ever matter physically, then the universe is not allowed to secretly treat them differently behind the scenes.
In other words, if there is no possible way to tell two states apart — not now, not later, not even in principle — then they must behave the same.
This might sound obvious, but it’s actually a powerful constraint. It rules out the idea that hidden, unobservable details could influence outcomes. The universe can’t “cheat” by using information that never shows up in reality.
2. No Ghost Possibilities That Never Become Real
The second result is even more striking.
The paper shows that you cannot have a leftover piece of “possibility” that:
- never becomes a real outcome,
- but still leaves a detectable trace on the world.
Think of it like this: you can’t have a ghost of an outcome that never actually happens, but still subtly influences what does happen.
If such “uncancellable leftovers” existed, the universe would contain effects that are not tied to any real event — which contradicts the idea that only facts carry physical meaning.
So the conclusion is:
All possibilities must either resolve into facts or cancel out completely. Nothing in between is allowed.
Why This Matters
These two results close important gaps in the broader VERSF argument.
They show that once you demand a universe capable of producing real, definite facts:
- You can’t have hidden, unobservable influences steering outcomes.
- You can’t have stray, half-real possibilities lingering in the background.
And together, these constraints push the structure of reality toward something very specific — the kind of mathematical framework we see in quantum mechanics.
The Bigger Picture
This doesn’t mean everything is fully explained yet. One key principle — called internal admissible closure (IAC) — is still assumed rather than derived, and understanding whether it can be proven from deeper ideas is the next big step.
But what this paper does show is something important:
The existence of facts is not a trivial requirement — it strongly shapes the rules the universe is allowed to follow.
Once you take “things must actually happen” seriously, the freedom to invent arbitrary laws disappears. The structure of reality becomes tightly constrained.
And that may be one of the reasons the universe looks the way it does.
