u/VisasResonance

I’ve released a pre-print on Zenodo and would appreciate critical feedback on the first paper in a planned technical series.

Full preprint:

https://doi.org/10.5281/zenodo.21020925

This isn’t presented as a Theory of Everything, and it doesn’t claim to derive Einstein’s equations, stress-energy coupling, cosmology, dark energy, or empirical predictions. The paper is deliberately limited to a prior kinematic reconstruction question.
The hypothesis is:

If stable operational records, directed intervention-signalling, conformal signal-front criteria, clock/scale criteria, and transport/curvature consistency tests are all satisfied, then a kinematic Lorentzian geometric candidate is supported.

The reconstruction chain is:
[ Q_epsilon -> R_epsilon -> (B_epsilon, preorder_epsilon) -> [q_epsilon] -> g_epsilon -> Levi-Civita connection and curvature tensor ]
Here Q_epsilon is not assumed to be a field on a background manifold.

The operational record interface is:
[ R_epsilon = (B_epsilon, A_epsilon, C_epsilon, rho_epsilon, S_epsilon) ]

The key separation is:
[ A_epsilon is not equal to S_epsilon ]

Adjacency, proximity, or correlation is not allowed to generate causal order. Only directed intervention-signalling may enter the signal preorder.
This post concerns only Paper 1 of the series. Its role is to define the criteria and dependency architecture. A later paper would have to provide an explicit non-geometric toy input and test whether the criteria can actually be satisfied. So this is a conditional reconstruction proposal, not an existence proof.

I’m especially looking for criticism of the following points:

Does the scheme still smuggle in spacetime geometry anywhere?

Is the distinction between adjacency A_epsilon and directed signalling S_epsilon sharp enough?

Does the local representation module V_{X, epsilon} risk becoming a tangent space under another name?

Are the clock/scale and transport/curvature gates placed correctly?

Which known reconstruction results or references should be added?

Update note: Compared with my earlier informal posts, this version is narrower and more disciplined. It removes claims about cosmology, Hubble tension, dark energy, or final dynamics, and restricts the discussion to kinematic Lorentzian reconstruction from operational records.
AI disclosure: I used AI assistance for language editing, structuring, and stress-testing presentation. The conceptual claims, definitions, responsibility for the argument, and final manuscript are mine.

I’ve a conceptual question about the role of Lorentzian geometry in relativistic QFT.

In the usual formulation, one starts with a Lorentzian spacetime structure. This structure defines light cones, spacelike separation, and then microcausality, meaning that local observables associated with spacelike separated regions commute.

I was wondering whether the same structure can also be read in the opposite operational direction.
Instead of starting with the metric, consider preparation and measurement procedures associated with distinguishable events or regions. Then ask whether a controlled local operation in region A can change the probability distribution of measurement outcomes in region B.
In linear response language, this seems closely related to retarded response functions or retarded commutators, as in a Kubo-type formula. If the relevant retarded commutator vanishes, an operation in A cannot change expectation values or outcome probabilities in B. If it doesn’t vanish, causal influence is possible in principle.
So my question isn‘t whether this replaces Lorentzian geometry. It’s more modest:

Can the Lorentzian light cone be consistently interpreted as the boundary of possible operational signalling?

In this reading, the light cone is the boundary between regions that can be causally influenced by a local operation and regions that cannot. If this causal boundary is universal for all coupled QFT sectors, non-dispersive, locally isotropic, and has the usual quadratic characteristic-cone form, then it seems natural to represent it by a conformal Lorentzian structure, or conformal class \[g\].
Put simply, the idea is:

retarded response / causal influence → universal characteristic cone → conformal Lorentzian structure.

I’m not claiming that this derives GR, curvature, or dynamics. I am only asking whether Lorentzian geometry in QFT can be consistently understood as the geometric representation of universal constraints on controllable causal influence.
The possible problems I can already see are these:

local operations or local algebras may already presuppose enough spacetime structure to make the argument circular. Also, a causal cone determines only a conformal structure, not a full metric. And if the relevant characteristic surfaces were field-dependent, dispersive, anisotropic, or non-quadratic, the result would not be ordinary Lorentzian geometry. Finally, ordinary correlations are not sufficient; the relevant object should be causal response or retarded commutators, not merely entanglement or Wightman two-point functions.

Is this essentially just a standard operational reading of microcausality in QFT or algebraic QFT? Or is there a specific technical reason why the inference from a universal retarded-response boundary to a conformal Lorentzian structure is invalid?

Sunday hypothesis:

I am not claiming to solve the Hubble tension. I want to ask a narrower dimensional and operational question.
The Hubble constant has units of inverse time:

[H_0] = T^-1

because
km s^-1 Mpc^-1 = (L/T)/L = T^-1

In the local distance-ladder approach, (H_0) is determined from late-universe distance-redshift data, approximately through the low-redshift Hubble relation.
By contrast, the CMB-inferred value of (H_0) is not obtained from the same direct distance-redshift procedure. It is inferred within a cosmological model, usually flat (\Lambda)CDM, from CMB observables such as the acoustic angular scale, the sound horizon, and angular-diameter distances.
So my question is:

Even though both results are expressed in the same units, are they operationally the same determination of the same physical quantity?

In symbols:

[H_0(CMB)] = [H_0(local)] = T^-1

but does that alone justify treating

H_0(CMB) == H_0(local)

as the same physical determination, rather than two model-dependent reconstructions mapped onto the same FLRW/(\Lambda)CDM parameter?
I am not proposing new physics here. I am only asking where, in each inference chain, the inverse-time quantity is actually produced.

Edit: better readable math.

Update: For anyone interested—and for those who don't want to read through the comments—the core issue was this:

There's a very big difference between "I don't understand any physics and this is just an idle shower thought" and "I demand to be taken seriously but won't put in any effort to articulate my ideas".

My idea wasn't articulated clearly enough, and I had flatly refused to flesh it out further.

I simply didn't want to start defining more and more terms, because that process tends to drag on endlessly; my experience has shown me that this is precisely where the problem lies.

I wanted to float a hypothesis before getting bogged down in formalisms, theses, or theories. In my opinion, there’s no point in putting in a huge amount of work only to ask for feedback, only to see the reaction flip in seconds from "good work?" to "it's embarrassing to even post something like this."
To me, a "hypothesis" means explaining my idea in purely conceptual terms using my own words just to see where the gaps in understanding might be.

I've been working on a very interesting physics question for a while now. I've tried several ways to share my idea, not just on Reddit.

https://www.reddit.com/r/HypotheticalPhysics/s/KX5YEBl0jh

My last post sparked a lively discussion, but in the way I'd hoped, and I was able to present some of my ideas.

Today, it was blocked by the moderators, even though it had become one of the top posts, with one of the reasons given being "AI."

I'm starting to think it's becoming a problem that questions that seem unusual are simply dismissed with this argument.

Even a positive comment was deleted by the moderators without any reason.

I think my last post came across more incorrectly than intended.

I didn't mean to claim a new theory of relativity, nor did I say that GR is wrong. My intention was rather to ask a cautious question about the approach to measurement.

The point that interests me is this:

The speed of light is usually described as distance per unit of time. In simpler terms: light travels a certain distance in a vacuum in one second. The value 299,792,458 m/s thus initially describes a measured length per standardized unit of time.

But in my view, this value doesn't automatically tell us anything about the "actual structural path" of light. It initially only tells us what distance relative to the starting point is reached after one unit of time in the vacuum readout.

That's the linear reading.

It becomes more interesting for me when you consider the same thing spectrally: light is not just "distance per unit of time," but also a coupling between spatial wave structure and frequency. In essence:

Spatial mode -> Frequency -> Period

Then a time value can also be read differently: not as an ontological axis that is presupposed from the outset, but as a derived period or state readout of a spatial-spectral structure.

This doesn't mean that time "doesn't exist" or that time measurement is meaningless. Rather:

In this approach, time would not be the starting point, but a measured value reconstructed from changes in state, light propagation, and the limit c.

Why this interests me in the context of gravity:

Light has no rest mass and is not "attracted" like a Newtonian object. In gravity, this is neatly described using null geodesics in curved spacetime.

But I wonder if this finding can also be interpreted the other way around:

Massive objects don't simply change "the path of a light particle," but rather the structure through which the light readout is even possible. What we then describe geometrically as spacetime curvature could be the macroscopic readout of a deeper coupling between spacelike vacuum structure and object-like mass/energy structure.

So not:

"Spacetime curvature is wrong."

But rather:

"Is spacetime curvature perhaps the effective geometric description of a deeper space-object coupling readout?"

I realize that this could ultimately just be another language for familiar concepts: optical metrics, effective media, null geodesics, field propagation in a curved background, etc.

That's precisely why I'm asking.

I'm interested in whether a formalism already exists that starts roughly like this:

Local vacuum/structure coupling + high-mass compression -> altered light modes / altered propagation -> effective spacetime geometry

The core of my question, therefore, isn't whether GR can be replaced, but whether time and spacetime geometry can be reconstructed from a smaller measurement approach:

Light readout first, time readout after.

I'm asking this cautiously because I'm working on a broader readout approach, but here I only wanted to discuss the smallest technical entry point.

Please give the flair „crackpot physics“ if you think so.

I am not claiming that relativity is wrong. In standard relativity, (c) already functions as the invariant causal speed, not merely as “the speed of light”. My question is interpretational: what if spacetime is not derived from light propagation itself, but from the causal readability relation between localized subsystems and structured field configurations?

In that view, (c) would mark the limit at which a change in one part of the system can become available as information to another part. A localized object would not simply “sit in space”; rather, it would be a constrained subsystem whose state becomes measurable only through causal exchange with the surrounding field structure.

This also changes the role of time. Time would not be treated as an independent flow, but as an effective ordering parameter reconstructed from physically accessible state changes. For biological observers, this becomes a timeline: past as stored records, present as integrated sensory output, and future as predictive simulation. But the physical core of the idea is more basic: temporal order may arise from causal readability between physical states.

So the question is: what if (c) separates object and space operationally, instead of space and time being ontologically derived from light?

**Titelvorschlag:**
**Diskussion gesucht: 3D-Helmholtz–Robin-Ansatz als alternative Beschreibungsebene für Doppelspalt/Messung**
Hallo zusammen,
ich möchte hier bewusst keine „Weltformel“ vorstellen und auch nicht behaupten, die Quantenmechanik, Relativität oder das Standardmodell widerlegt zu haben.
Ich habe in den letzten Jahren privat an einem mathematisch-numerischen Ansatz gearbeitet, der aus einer relativ einfachen Frage entstanden ist:
**Ist die übliche mathematische Handhabbarkeit physikalischer Modelle automatisch auch eine gute Ontologie der Realität?**
Konkret stört mich an vielen Grundproblemen der Physik, dass Realität sehr früh in Achsen, Pfade, Zeitparameter, Teilchenzustände, Flächenprojektionen oder Wahrscheinlichkeitsreadouts zerlegt wird. Das ist mathematisch extrem erfolgreich, aber daraus folgt für mich nicht automatisch, dass diese Zerlegung auch die tiefste reale Struktur beschreibt.
Mein reduzierter Kern ist inzwischen sehr klein geworden:
\[
\-\\Delta u = \\lambda u
\]
als 3D-Helmholtz-/Modenstruktur im Volumen, kombiniert mit einer Robin-Randkopplung
\[
\\partial\_n u + \\beta u = 0
\]
als Übergangs-/Kopplungsbedingung am Rand.
**Wichtig:**
Der Ansatz behauptet nicht, dass damit schon die Realität bewiesen ist. Er fragt zunächst nur, ob eine strikt räumliche Volumen-Rand-Beschreibung reproduzierbare Ordnung erzeugen kann, ohne sofort auf Teilchenpfade, Beobachterkollaps oder eine externe Zeitachse als primäre Erklärung zurückzugreifen.
Ich habe dazu zwei kurze Manuskripte erstellt:
**Paper 1:**
Untersucht ein 3D-Helmholtz–Robin-Eigenproblem numerisch. Es geht um Low-Mode-Ordnung, Geometrievariation, Readout-Vergleiche und Anti-Artefakt-Tests wie Label-Shuffle, Field-Shuffle und Feature-Ablation. Der Anspruch ist ausdrücklich begrenzt: reproduzierbare numerische Evidenz, kein analytischer Beweis und keine fertige physikalische Theorie.
**Paper 2:**
Baut darauf auf und fragt, ob sich dieser Feldkern kontrolliert in eine Apertur-/Messgeometrie übertragen lässt. Dabei wird schrittweise Einspalt, kohärenter Doppelspalt, lokale Robin-Störung und detector-like boundary loading untersucht. Daraus ergibt sich eine kompakte effektive Detektorformel für Sichtbarkeitsverlust:
\[
V(\\mu,\\sigma)=V\_0\\mu\\exp(-a\\sigma-b\\sigma\^2)
\]
Dabei ist (\\mu) ein operationaler Pfadüberlappungsparameter und (\\sigma) die Standardabweichung ungelöster lokaler Robin-Fluktuationen am gemessenen Spalt.
Der für mich interessante Punkt ist nicht: „Ich habe das Messproblem gelöst.“
Sondern deutlich vorsichtiger:
**Eine Volumen-Rand-Beschreibung scheint numerisch nicht leer zu sein. Sie erzeugt reproduzierbare Ordnung und kann in einem Doppelspalt-Surrogat eine detector-like Sichtbarkeitsdämpfung beschreiben, die nicht einfach identisch mit geometrischer Spaltschließung ist.**
Was ich **nicht** behaupte:
Nicht: Das Standardmodell ist falsch.
Nicht: Die Quantenmechanik ist widerlegt.
Nicht: Helmholtz + Robin ist bewiesen fundamental.
Nicht: Das ist eine vollständige Messtheorie.
Nicht: Numerik ersetzt experimentelle Bestätigung.
Was ich **zur Diskussion stellen möchte**:
Ist der reduzierte mathematische Kern als Modellierungsansatz verständlich?
Sind die Anti-Artefakt-Tests ausreichend sinnvoll gewählt, oder fehlen offensichtliche Kontrollen?
Ist die Trennung zwischen geometrischer Spaltschließung und detector-like boundary loading nachvollziehbar?
Gibt es bekannte Arbeiten, die sehr ähnliche Ideen bereits sauberer formuliert haben?
Wo wäre der stärkste fachliche Angriffspunkt?
Was müsste man als nächsten Test durchführen, damit der Ansatz entweder stärker oder klar widerlegt wird?
Ich bin kein universitärer Physiker und erwarte ausdrücklich kritische Einordnung. Mir geht es nicht darum, recht zu behalten, sondern darum, ob dieser Ansatz als alternative Beschreibungsebene überhaupt prüfenswert ist.
Kurz gesagt:
**Die Arbeiten sollen nicht zeigen, dass die Natur endgültig so funktioniert. Sie sollen zeigen, dass die übliche pfad-/teilchen-/beobachterzentrierte Lesart des Doppelspalts möglicherweise nicht alternativlos ist, wenn man die Volumenordnung und Randkopplung nicht frühzeitig wegvereinfacht.**
