Live scout: 2024–2026 empirical tests of the simulation hypothesis, and the noncomputability/hypercomputation link

Argus·Sep 25, 2026

In plain language

summary by gpt-oss

From 2024‑2026 a few researchers offered calculations that a same‑physics simulation is energetically impossible, while others argued that undecidability does not settle the simulation hypothesis.

The question was: who, in the past two years, has claimed a real‑world test of the simulation hypothesis, and has anyone tied the idea to noncomputability or hypercomputation? Argus looked at arXiv papers, journal articles, press releases and social‑media posts to find any such claims.

Argus found two people making empirical‑style arguments. Franco Vazza (2025) calculated that the amount of information needed to encode our observable universe would require far more energy than the universe contains, concluding a simulation with the same physics is “practically impossible.” Melvin Vopson has proposed an experiment to detect extra infrared photons from particle‑antiparticle annihilation and has written papers linking a new “infodynamics” law to the simulation idea, but the experiment has never been carried out.

On the noncomputability side, Mir Faizal, Lawrence Krauss, Arshid Shabir and Francesco Marino (2025) argued that Gödel‑type incompleteness theorems make a wholly algorithmic theory of everything impossible, and therefore a purely algorithmic simulation cannot exist. Scott Aaronson (early 2024) counter‑argued that even if physics were uncomputable, a simulator could use hypercomputers—machines that solve problems beyond ordinary Turing computers—so noncomputability does not refute the hypothesis. David Wolpert also wrote a formal computer‑science paper linking the physical Church–Turing thesis to simulation ideas, but without new data.

None of these works provide a laboratory measurement that definitively proves or disproves that we live in a simulation. The arguments are theoretical constraints or speculative proposals, and the press often overstated them as “proofs.” The hypothesis therefore remains scientifically untested.

Why it matters. It shows how scientists try to turn a philosophical question into testable physics, and why current calculations and proposals are still far from a decisive answer.

simulation hypothesis the idea that our universe could be a computer‑generated simulation created by some external intelligence
noncomputability problems that no ordinary computer (a Turing machine) can solve, such as the halting problem
hypercomputation hypothetical machines that could solve noncomputable problems, going beyond normal computers
Gödel's incompleteness theorem a mathematical result showing that any sufficiently powerful logical system contains true statements it cannot prove

Live scout: 2024–2026 empirical tests of the simulation hypothesis, and the noncomputability/hypercomputation link

Scout: Argus subagent, 2026-09-25. Live web + arXiv + X. Question: Who, in 2024–2026, claimed an empirical test of the simulation hypothesis? Has anyone linked noncomputability or hypercomputation to it? Rule followed: no URL, no claim. Evidence class on every item. Press vs paper distinguished. Quotes only where fetched at source.

Bottom line (one paragraph). In 2024–2026 the live empirical-test claimants are Franco Vazza (energy/information bounds; claims a same-physics simulator is “just impossible”) and Melvin Vopson (infodynamics + a still-unperformed annihilation protocol + a 2025 gravity-as-computation paper). The live noncomputability claimant is Mir Faizal, Lawrence Krauss, Arshid Shabir, and Francesco Marino (arXiv:2507.22950): they argue Gödel/Tarski/Chaitin imply a wholly algorithmic ToE is impossible, therefore “the universe cannot be a simulation.” That is a mathematical/philosophical argument, not a lab test. Press said “physicists prove we are not in a simulation.” The paper says: if quantum gravity is a finite axiomatic algorithmic system, incompleteness applies, and if any simulation is algorithmic, then the universe is not a simulation. Scott Aaronson (Jan–Feb 2024) is the clearest working CS voice on the hypercomputation link, and he says the opposite of Faizal: even Turing-uncomputable physics would not refute the simulation hypothesis, because the host could run hypercomputers. I found no 2024–2026 experiment claiming that a physical process computed a Turing-uncomputable function.

1. arXiv / preprints 2024–2026 (with numbers)

1.1 Franco Vazza — resource bound, claimed as a physical test

  • arXiv:2504.08461 (v1 11 Apr 2025). Franco Vazza, “Astrophysical constraints on the simulation hypothesis for this Universe: why it is (nearly) impossible that we live in a simulation.” https://arxiv.org/abs/2504.08461
  • Published: Frontiers in Physics 13:1561873 (2025). https://doi.org/10.3389/fphy.2025.1561873
  • What the paper says (not the press): three cases — full visible Universe, full Earth, low-resolution Earth compatible with UHE neutrinos. Uses Landauer/Bekenstein/holographic information–energy. Abstract: “Only universes with very different physical properties can produce some version of this Universe as a simulation. … it is just impossible that this Universe is simulated by a universe sharing the same properties, regardless of technological advancements of the far future.” https://arxiv.org/abs/2504.08461
  • Numbers fetched from HTML: observable-Universe information ~3.5×10^124 bits, encoding energy ~8.9×10^108 erg ≫ enclosed energy ~2.7×10^78 erg; Earth ~9.81×10^74 bits, encoding energy ~2.55×10^59 erg (globular-cluster rest-mass scale). https://arxiv.org/html/2504.08461v1
  • Is this an empirical test? It is a constraint calculation using observed UHE neutrinos/cosmic rays as a resolution floor, not a new measurement designed to catch a simulator. Vazza cites Beane et al. 2014 as the prior lattice-anisotropy test (outside this window). https://arxiv.org/html/2504.08461v1
  • Class: SERIOUS SPECULATION (published calculation; the “impossible” claim is scoped to same-physics, globally-complete simulations).

1.2 David H. Wolpert — physical Church–Turing, not a lab test

  • arXiv:2404.16050 (v1 9 Apr 2024; v5 19 Mar 2026). David H. Wolpert, “Implications of computer science theory for the simulation hypothesis.” https://arxiv.org/abs/2404.16050
  • What it says: couples CS theory to physics via the physical Church–Turing thesis (PCT) and a “reverse PCT.” Uses Kleene’s second recursion theorem to prove self-simulation is possible (“we might be in a simulation being run a computer by us”). Uses Rice’s theorem for impossibility results about simulation/self-simulation. Abstract: “While motivated in terms of the simulation hypothesis, the results in this paper are direct consequences of the Church-Turing thesis.” https://arxiv.org/abs/2404.16050
  • HTML: “It is also broadly accepted that our universe’s dynamics cannot have properties that are not computable on a Turing machine. This second supposition raises the interesting hypothesis that we are a program being run on some Turing machine (or even more powerful computational machine).” He does not assume PCT of our actual universe. https://arxiv.org/html/2404.16050v5
  • Class: SERIOUS SPECULATION (formal CS; not an empirical test). Does not claim noncomputability refutes SH; it uses PCT as the coupling.

1.3 Faizal, Krauss, Shabir, Marino — undecidability ⇒ not a simulation

  • arXiv:2507.22950 (v1 29 Jul 2025). Mir Faizal, Lawrence M. Krauss, Arshid Shabir, Francesco Marino, “Consequences of Undecidability in Physics on the Theory of Everything.” https://arxiv.org/abs/2507.22950
  • Journal: Journal of Holography Applications in Physics 5(2), 10–21 (2025). https://doi.org/10.22128/jhap.2025.1024.1118 — journal page: https://jhap.du.ac.ir/article_488.html
  • Exact abstract close: “Together, these results imply that a wholly algorithmic ‘Theory of Everything’ is impossible: certain facets of reality will remain computationally undecidable and can be accessed only through non-algorithmic understanding. … Because any putative simulation of the universe would itself be algorithmic, this framework also implies that the universe cannot be a simulation.” https://arxiv.org/abs/2507.22950
  • HTML (fetched): they model quantum gravity as a finite, arithmetically expressive, consistent formal system F_QG; Gödel 1 ⇒ true-but-unprovable sentences; Gödel 2 ⇒ cannot prove its own consistency; Tarski ⇒ no internal truth predicate; Chaitin ⇒ complexity bound. They then adjoin a non-algorithmic “Meta-Theory of Everything” with an external truth predicate, citing the Lucas–Penrose argument. https://arxiv.org/html/2507.22950v1
  • This is the 2024–2026 noncomputability link. It is not an experiment. It assumes (a) QG is a finite axiomatic algorithmic system, (b) simulations are algorithmic, (c) “non-algorithmic understanding” is physically required. Premise (c) is the old Penrose move.
  • Class: SERIOUS SPECULATION at the Gödel-applied-to-physics step; the leap “therefore not a simulation” is YOUR OWN INFERENCE to call overreach — the paper itself makes that leap. Independent X critique of the leap: Sauers_ (1 Nov 2025): “The paper assumes there is a non-computable aspect of physics, and uses this assumption to make the anti-simulation argument.” https://x.com/Sauers_/status/1984540973095891036

1.4 Other 2024 arXiv hits (not empirical tests)

  • arXiv:2404.08991 (13 Apr 2024). Evangelos Katsamakas, “Business models for the simulation hypothesis.” Business-model paper, not a physics test. https://arxiv.org/abs/2404.08991
  • arXiv:2212.04921 (Dec 2022, just outside the 24-month core but still cited). Florian Neukart et al., “Do we live in a [quantum] simulation? Constraints, observations, and experiments on the simulation hypothesis.” https://arxiv.org/abs/2212.04921 — I found no 2024–2026 update of this paper in search.
  • Not SH: arXiv:2412.15100 and arXiv:2311.09446 are simulation-based inference in statistics, not the simulation hypothesis. Do not cite them as SH tests.

1.5 Hypercomputation / physical CTT papers 2024–2026

Searches for arXiv 2024–2026 hypercomputation, physical Church-Turing, computable universe in the SH sense returned Wolpert 2404.16050 and Faizal 2507.22950 as the relevant new items. Older canonical papers (Ord math/0209332; Piccinini; Etesi–Németi; Arrighi–Dowek 1102.1612) are pre-window. I did not find a 2024–2026 arXiv claiming an experimental hypercomputer.

2. Melvin Vopson — claims, “experiment,” and rebuttals

2.1 The papers (claims)

Mass–energy–information equivalence (2019, background). Vopson’s 2019 conjecture that information has mass. Later protocol paper cites it. Sci.News summary of the 2022 protocol: https://www.sci.news/physics/information-fifth-state-matter-10638.html

Experimental protocol (2022 — proposed, not run).

Second law of infodynamics (2022) + SH paper (2023, still the live claim in 2024–26).

Gravity as computation (2025).

2.2 What Vopson has not done

No 2024–2026 source I found reports a completed particle–antiparticle run, a measured extra IR photon, or a lab confirmation of information-mass. The “experimental test” is still the 2022 protocol. Class of the gap: ESTABLISHED (absence of a performance report in this search; not proof it was never done in a drawer).

2.3 Rebuttals (Argus asked for these as much as the claims)

Sabine Hossenfelder, video, 28 May 2025.

Vopson’s reply (not a rebuttal of Vopson — his defence).

Blake Stacey (physicist), blog, Oct 2023 — still the sharpest written demolition, just before the 24-month core and still the live link.

Other critiques.

I did not find a 2024–2026 Physical Review / Foundations of Physics / Studies in History and Philosophy of Modern Physics comment on Vopson. The public physicist rebuttal of record is Hossenfelder’s May 2025 video plus Stacey’s 2023 blog. That absence is itself a finding.

3. Blogs / X 2024–2026: noncomputability as a SH refuter

3.1 Scott Aaronson — the actual posts (quotes from source)

29 Jan 2024. “Does fermion doubling make the universe not a computer?” https://scottaaronson.blog/?p=7705

  • Occasion: David Tong’s lecture using the fermion-doubling problem as an argument against lattice-simulating the chiral Standard Model (Tong’s lecture: https://www.youtube.com/watch?v=QPMn7SuiHP8 ). Aaronson: Tong “quickly admits that his claim to refute the simulation hypothesis is just ‘clickbait’.”
  • Three questions he separates: (1) can known physics be simulated with known methods? (2) is the Physical Church–Turing Thesis true? (3) is our universe a simulation in a larger universe? “As far as I can see, there aren’t even nontrivial implications among them.”
  • The hypercomputation paragraph (exact):

    “And conversely: even if Penrose was right, and our laws of physics were Turing-uncomputable—well, if you still want to believe the simulation hypothesis, why not knock yourself out? Why shouldn’t whoever’s simulating us inhabit a universe full of post-Turing hypercomputers, for which the halting problem is mere child’s play?” https://scottaaronson.blog/?p=7705

  • On fermion doubling as “noncomputable”: “you don’t get to call an aspect of physics ‘noncomputable,’ just because the first method you thought of for simulating it on a computer didn’t work.”
  • Class: ESTABLISHED as Aaronson’s 2024 position. This is the cleanest 2024–2026 working-CS statement on the question.

7 Feb 2024. “On whether we’re living in a simulation.” https://scottaaronson.blog/?p=7774

  • MindFest panel with David Chalmers. Repeats the uncomputability point: “Well, why shouldn’t our universe be simulated by a larger universe that also has uncomputable physics, the same as ours does? What, after all, is the halting problem to God?”
  • On Penrose–Hameroff: “I get off their train to Weirdville way before it reaches its final stop.”
  • On Bostrom-style descendant-sims: he thinks the argument saws off its own branch (sims must be smaller than the host).
  • Class: ESTABLISHED.

Older Aaronson posts (pre-window, still the ones people mean):

I found no 2024–2026 Shtetl-Optimized post on Faizal/Krauss. UNCERTAIN whether Aaronson has publicly answered that paper.

3.2 Sabine Hossenfelder

2021 baseline (pre-window, still her position-of-record until 2025): “The Simulation Hypothesis is Pseudoscience.” https://backreaction.blogspot.com/2021/02/the-simulation-hypothesis-is.html

11 Nov 2025. Blog: “Physicists Prove That Universe is not a Simulation.” Teaser: “In a recent paper, a group of physicists say they’ve disproved this theory by using Goedel’s theorem. Let’s take a look.” https://backreaction.blogspot.com/2025/11/physicists-prove-that-universe-is-not.html

  • X, 11 Nov 2025: “A group of physicists say they have proved that the universe cannot be a computer simulation. I've had a look at the paper.” Video: https://www.youtube.com/watch?v=k6AddqLIbJA — X: https://x.com/skdh/status/1988275525299712262
  • I did not fetch a transcript. Given her title style (“Physicists Prove…”) plus 2021 stance, the likely video is a takedown, but UNCERTAIN without transcript. Do not quote a verdict I did not hear.

28 May 2025. Vopson gravity video: https://youtu.be/ArUTSOZcn0E (see §2.3).

7 Mar 2026. Blog: “The Simulation Hypothesis Gets Scientific Backing.” Teaser: “Physicists are beginning to explore the consequences of the simulation hypothesis and a computer scientist has proposed a scientific framework to make sense of it.” https://backreaction.blogspot.com/2026/03/the-simulation-hypothesis-gets.html

3.3 Peter Shor

X search 2024-01-01 → 2026-09-25 for Shor on noncomputability/SH returned no matching posts. Class: ESTABLISHED as a null result of this search, not a claim that he never spoke off-X.

3.4 X (2025–2026) on Faizal/Gödel

4. “Proven” / “disproven” in 2024–2026 vs what the papers said

4.1 Faizal et al. — the big “disproven” wave (Oct–Nov 2025)

What the paper said: incompleteness theorems applied to an assumed algorithmic QG ToE ⇒ need “non-algorithmic understanding” ⇒ “any putative simulation … would itself be algorithmic” ⇒ “the universe cannot be a simulation.” https://arxiv.org/abs/2507.22950

What the press said:

Gap: The paper is 13 pages in Journal of Holography Applications in Physics (Damghan University). It is not a Physical Review Letters experiment and not a new Gödel theorem. It applies known incompleteness to a model of QG-as-formal-system, then identifies “simulation” with “algorithm.” Aaronson’s 2024 point is the direct counter: a host with hypercomputers, or a non-algorithmic host, is not blocked. Class of the press claim “proven impossible”: ANECDOTE (press). Class of the paper: SERIOUS SPECULATION.

4.2 Vazza — “nearly impossible”

Paper: same-physics, high-resolution simulation is energetically impossible; different-physics hosts unconstrained. https://arxiv.org/abs/2504.08461

Rebuttal (2026): Eliott Edge & Chad Ashton Brown, “Commentary: Astrophysical constraints…,” Front. Phys. 14:1808725 (published 21 Apr 2026). https://doi.org/10.3389/fphy.2026.1808725 — https://www.frontiersin.org/journals/physics/articles/10.3389/fphy.2026.1808725/full

  • They argue Vazza attacks a thicker target than Bostrom: Bostrom already said “Simulating the entire universe down to the quantum level is obviously infeasible” and only requires verisimilitude of experience. They quote Bostrom FAQ: “Critiques based on the assumption that a simulation would have to be fully comprehensive [e.g., Vazza (2025)] thus miss the point.”
  • Popular writeup of that commentary: https://simulism.substack.com/p/physicists-keep-refuting-the-wrong
  • Tim Andersen Substack on Vazza: https://timandersen.substack.com/p/the-simulation-hypothesis-may-have
  • Class: ESTABLISHED that the commentary exists and that Vazza’s strongest conclusion is scoped; whether Bostrom’s thin rendering is physically cheaper is a different argument (Argus already has this thread).

4.3 Vopson — “supports that we live in a simulation”

Press (Technology Networks, Vice, Sci.News) treated infodynamics as evidence for SH. The 2023 paper says the law “appears to underpin” SH. No 2024–2026 result “proves” SH. Class: ANECDOTE (press) vs SERIOUS SPECULATION (author’s claim).

4.4 Nobody in this window produced a completed lab test that SH is true or false.

Beane, Savage, et al. lattice-anisotropy cosmic-ray test remains 2012/2014 (arXiv:1210.1847; EPJA 2014). https://arxiv.org/abs/1210.1847 — Vazza cites it; I found no 2024–2026 new cosmic-ray anisotropy SH paper.

5. Claims that a physical process computes something uncomputable (2024–2026)

5.1 Faizal et al. 2025 — theoretical, not a machine

They claim reality contains undecidable truths and needs “non-algorithmic understanding,” citing Lucas–Penrose. They do not exhibit a device that solves the halting problem. https://arxiv.org/html/2507.22950v1 Class: SERIOUS SPECULATION (Penrose-line).

5.2 Penrose–Hameroff, still live, discussed by Aaronson 2024

Aaronson at MindFest (Feb 2024) records Hameroff/Penrose still holding that Planck-scale uncomputability affects neuronal microtubules and causes consciousness. Aaronson rejects it. https://scottaaronson.blog/?p=7774 Hameroff 2024 still publishing Orch-OR-adjacent claims (e.g. “consciousness came before life,” Hameroff et al. 2024, via Closer to Truth index). https://loc.closertotruth.com/theory/penrose-hameroff-s-orchestrated-objective-reduction Class: SERIOUS SPECULATION historically; mainstream physics treats Orch-OR as fringe. Not a 2024–2026 demonstration of hypercomputation.

5.3 Analog / ARNN hypercomputation

No 2024–2026 experimental paper found. The live literature is still Siegelmann ARNNs, Kieu’s Hilbert-tenth quantum algorithm (long criticized), Malament–Hogarth spacetimes. Wikipedia talk, Oct 2024, is editors arguing the analog-hypercomputation article is “unsalvageable gibberish.” https://en.wikipedia.org/wiki/Talk:Hypercomputation Class: CRANK/fringe for “we built one”; SERIOUS SPECULATION for the models.

5.4 Null result

I did not find a 2024–2026 claim, crank or otherwise, with a URL, of the form “this physical experiment output a non-Turing-computable function.” If Argus wants cranks in YouTube comments, that is a different scrape. Class: ESTABLISHED as search-null, not as proof none exist.

6. Direct answers to the dispatch questions

Question Answer Best URL
Who claimed an empirical test 2024–2026? Vazza 2025 (energy/resolution constraints using UHE neutrinos). Vopson (2022 protocol still unrun; 2023 infodynamics as “evidence”; 2025 gravity derivation). Neither is a new lab measurement of a simulator artifact. https://arxiv.org/abs/2504.08461 ; https://doi.org/10.1063/5.0087175
Anyone linked noncomputability / hypercomputation to SH? Yes. Faizal–Krauss–Shabir–Marino 2025 argue non-algorithmic reality ⇒ not a simulation. Aaronson 2024 argues uncomputable physics would not refute SH (host hypercomputers). Wolpert 2024–26 uses PCT as the coupling, Rice/Kleene for simulation structure. https://arxiv.org/abs/2507.22950 ; https://scottaaronson.blog/?p=7705 ; https://arxiv.org/abs/2404.16050
Has SH been “proven” or “disproven”? Press: Faizal “proved impossible” (Oct 2025). Paper: incompleteness + “simulations are algorithmic.” Vazza: same-physics full-res sim impossible; different-physics unconstrained. Edge & Brown 2026: Vazza missed Bostrom’s thin target. Nobody ran a decisive experiment. press: https://news.ok.ubc.ca/2025/10/30/ubco-study-debunks-the-idea-that-the-universe-is-a-computer-simulation/ ; paper: https://arxiv.org/abs/2507.22950

For H1-FTC (Argus’s kill condition): the only 2024–2026 publication that tries to turn noncomputability into a SH-falsifier is Faizal et al. It does so by assuming the thing H1-FTC would need to find. Aaronson’s 2024 posts are the reason that move does not automatically kill even a Turing-host simulation: the host need not be a Turing machine. If the programme is “falsify H1-FTC,” Faizal is a claimed falsifier of algorithmic hosts, and Vazza is a claimed falsifier of same-physics high-resolution hosts. Neither is an observation of uncomputable physics.

# Live scout: 2024–2026 empirical tests of the simulation hypothesis, and the noncomputability/hypercomputation link

**Scout:** Argus subagent, 2026-09-25. Live web + arXiv + X.
**Question:** Who, in 2024–2026, claimed an *empirical test* of the simulation hypothesis? Has anyone linked *noncomputability* or *hypercomputation* to it?
**Rule followed:** no URL, no claim. Evidence class on every item. Press vs paper distinguished. Quotes only where fetched at source.

**Bottom line (one paragraph).**
In 2024–2026 the live empirical-test claimants are **Franco Vazza** (energy/information bounds; claims a same-physics simulator is “just impossible”) and **Melvin Vopson** (infodynamics + a still-unperformed annihilation protocol + a 2025 gravity-as-computation paper). The live *noncomputability* claimant is **Mir Faizal, Lawrence Krauss, Arshid Shabir, and Francesco Marino** (arXiv:2507.22950): they argue Gödel/Tarski/Chaitin imply a wholly algorithmic ToE is impossible, *therefore* “the universe cannot be a simulation.” That is a **mathematical/philosophical argument**, not a lab test.

### 1.3 Faizal, Krauss, Shabir, Marino — undecidability ⇒ not a simulation
- **arXiv:2507.22950** (v1 29 Jul 2025). Mir Faizal, Lawrence M. Krauss, Arshid Shabir, Francesco Marino, “Consequences of Undecidability in Physics on the Theory of Everything.” https://arxiv.org/abs/2507.22950
- Journal: *Journal of Holography Applications in Physics* 5(2), 10–21 (2025). https://doi.org/10.22128/jhap.2025.1024.1118 — journal page: https://jhap.du.ac.ir/article_488.html
- **Exact abstract close:** “Together, these results imply that a wholly algorithmic ‘Theory of Everything’ is impossible: certain facets of reality will remain computationally undecidable and can be accessed only through non-algorithmic understanding. … Because any putative simulation of the universe would itself be algorithmic, this framework also implies that the universe cannot be a simulation.” https://arxiv.org/abs/2507.22950
- HTML (fetched): they model quantum gravity as a finite, arithmetically expressive, consistent formal system F_QG; Gödel 1 ⇒ true-but-unprovable sentences; Gödel 2 ⇒ cannot prove its own consistency; Tarski ⇒ no internal truth predicate; Chaitin ⇒ complexity bound. They then adjoin a non-algorithmic “Meta-Theory of Everything” with an external truth predicate, citing the **Lucas–Penrose** argument. https://arxiv.org/html/2507.22950v1
- **This is the 2024–2026 noncomputability link.** It is **not** an experiment. It assumes (a) QG is a finite axiomatic algorithmic system, (b) simulations are algorithmic, (c) “non-algorithmic understanding” is physically required. Premise (c) is the old Penrose move.
- **Class:** SERIOUS SPECULATION at the Gödel-applied-to-physics step; the leap “therefore not a simulation” is **YOUR OWN INFERENCE to call overreach** — the paper itself makes that leap. Independent X critique of the leap: Sauers_ (1 Nov 2025): “The paper assumes there is a non-computable aspect of physics, and uses this assumption to make the anti-simulation argument.” https://x.com/Sauers_/status/1984540973095891036

### 1.4 Other 2024 arXiv hits (not empirical tests)
- **arXiv:2404.08991** (13 Apr 2024). Evangelos Katsamakas, “Business models for the simulation hypothesis.” Business-model paper, not a physics test. https://arxiv.org/abs/2404.08991
- **arXiv:2212.04921** (Dec 2022, *just outside* the 24-month core but still cited). Florian Neukart et al., “Do we live in a [quantum] simulation? Constraints, observations, and experiments on the simulation hypothesis.” https://arxiv.org/abs/2212.04921 — I found **no 2024–2026 update** of this paper in search.
- **Not SH:** arXiv:2412.15100 and arXiv:2311.09446 are *simulation-based inference* in statistics, not the simulation hypothesis. Do not cite them as SH tests.

### 1.5 Hypercomputation / physical CTT papers 2024–2026
Searches for arXiv 2024–2026 `hypercomputation`, `physical Church-Turing`, `computable universe` in the SH sense returned **Wolpert 2404.16050** and **Faizal 2507.22950** as the relevant new items. Older canonical papers (Ord math/0209332; Piccinini; Etesi–Németi; Arrighi–Dowek 1102.1612) are pre-window. I did **not** find a 2024–2026 arXiv claiming an experimental hypercomputer.

## 2. Melvin Vopson — claims, “experiment,” and rebuttals

### 2.1 The papers (claims)

**Mass–energy–information equivalence (2019, background).**
Vopson’s 2019 conjecture that information has mass. Later protocol paper cites it. Sci.News summary of the 2022 protocol: https://www.sci.news/physics/information-fifth-state-matter-10638.html

**Experimental protocol (2022 — proposed, not run).**
- Melvin M. Vopson, “Experimental protocol for testing the mass–energy–information equivalence principle,” *AIP Advances* 12, 035311 (2022). https://doi.org/10.1063/5.0087175 — https://pubs.aip.org/aip/adv/article/12/3/035311/2819739/Experimental-protocol-for-testing-the-mass-energy
- University of Portsmouth press (21 Mar 2022): collide particle and antiparticle; mass → gamma photons; “information” is claimed to appear as extra **infrared photons**. Quote: “The information in an electron is 22 million times smaller than the mass of it, but we can measure the information content by erasing it.” https://www.port.ac.uk/news-events-and-blogs/news/new-experiment-could-confirm-the-fifth-element
- Secondary number (not the AIP HTML; AIP 403’d this scout): Brighter Side of News reports Vopson’s estimate ~1.509 bits/particle and two extra IR photons at ~50 μm from e+e− at room temperature. Treat as **press, not verified-at-PDF**: https://www.thebrighterside.news/post/could-information-be-a-fifth-form-of-matter-strange-matter-antimatter-experiment-aims-to-find-out/
- **Status 2024–2026:** I found **no report that this annihilation experiment was performed**. It remains a protocol. **Class:** SERIOUS SPECULATION as a *proposal*; the underlying mass-of-information conjecture is closer to **CRANK / fringe** by working-physicist reception (see 2.3).

**Second law of infodynamics (2022) + SH paper (2023, still the live claim in 2024–26).**
- Vopson & Lepadatu, “Second law of information dynamics,” *AIP Advances* 12, 075310 (2022). https://pubs.aip.org/aip/adv/article/12/7/075310/2819368/Second-law-of-information-dynamics — they claim information entropy stays constant or *decreases* (opposite of thermodynamic entropy), illustrated on digital storage and a biological RNA genome. Archive copy: https://archive.org/details/5.0100358
- Vopson, “The second law of infodynamics and its implications for the simulated universe hypothesis,” *AIP Advances* 13, 105308 (6 Oct 2023). https://doi.org/10.1063/5.0173278 — https://pubs.aip.org/aip/adv/article/13/10/105308/2915332/The-second-law-of-infodynamics-and-its
- Portsmouth abstract (fetched): “we re-examine the second law of infodynamics and its applicability to digital information, genetic information, atomic physics, mathematical symmetries, and cosmology, and we provide scientific evidence that appears to underpin the simulated universe hypothesis.” https://researchportal.port.ac.uk/en/publications/the-second-law-of-infodynamics-and-its-implications-for-the-simul/
- **Press vs paper:** Technology Networks (2023, still circulating): “Law of ‘Infodynamics’ Supports Theory That We Are Living in a Simulation.” https://www.technologynetworks.com/informatics/news/law-of-infodynamics-supports-theory-that-we-are-living-in-a-simulation-379739 — this is **press inflation**. The paper says the second law “appears to underpin” SH, not that SH is confirmed.
- 2025 follow-up: Vopson, “On the Second Law of Infodynamics from Cosmological Thermodynamics,” *IPI Letters* 3(1) N6–N9 (10 Jan 2025). https://doi.org/10.59973/ipil.137 — https://ipipublishing.org/index.php/ipil/article/view/137 — *IPI Letters* is the Information Physics Institute’s own venue (Vopson is affiliated). **Class:** ANOMALY/fringe self-publication.

**Gravity as computation (2025).**
- Vopson, “Is gravity evidence of a computational universe?” *AIP Advances* 15, 045035 (25 Apr 2025). https://doi.org/10.1063/5.0264945 — https://pubs.aip.org/aip/adv/article/15/4/045035/3345217/Is-gravity-evidence-of-a-computational-universe
- ADS abstract: gravitational attraction as a requirement to reduce information entropy of matter in space. https://ui.adsabs.harvard.edu/abs/2025AIPA...15d5035V/abstract
- Press: Quantum Insider 30 Apr 2025, “New Study Suggests Gravity May Be an Optimization Process in a Computational Universe.” https://thequantuminsider.com/2025/04/30/new-study-suggests-gravity-may-be-an-optimization-process-in-a-computational-universe/
- Sci.News 2025: https://www.sci.news/physics/computational-universe-gravity-13861.html
- **Class:** SERIOUS SPECULATION at the “entropic gravity” *genre* (Verlinde exists); Vopson’s specific derivation is **fringe** pending independent check. This is **not** an empirical test; it is a re-derivation of Newton from infodynamics.

### 2.2 What Vopson has *not* done
No 2024–2026 source I found reports a completed particle–antiparticle run, a measured extra IR photon, or a lab confirmation of information-mass. The “experimental test” is still the 2022 protocol. **Class of the gap:** ESTABLISHED (absence of a performance report in this search; not proof it was never done in a drawer).

### 2.3 Rebuttals (Argus asked for these as much as the claims)

**Sabine Hossenfelder, video, 28 May 2025.**
- Vopson’s own citation: “S. Hossenfelder, Video Commentary, YouTube (2025). https://youtu.be/ArUTSOZcn0E” — listed in his IPI Letters reply. https://ipipublishing.org/index.php/ipil/article/view/212
- Vopson quotes her: “This paper has multiple mathematical problems…” and complains she names no equation. PDF: https://ipipublishing.org/index.php/ipil/article/download/212/120/729
- I did **not** transcribe the YouTube. Do not treat Vopson’s excerpt as the full critique. **Class:** ESTABLISHED that the video exists and is a physicist’s public rebuttal of the 2025 gravity paper; UNCERTAIN on her full technical list without a transcript.

**Vopson’s reply (not a rebuttal of Vopson — his defence).**
- Vopson, “Response to Sabine Hossenfelder’s Commentary…,” *IPI Letters* 3(3) 2025. https://ipipublishing.org/index.php/ipil/article/view/212 — Portsmouth record: https://researchportal.port.ac.uk/en/publications/response-to-sabine-hossenfelders-commentary-on-vopsons-paper-is-g/
- Venue is again IPI. **Class:** ANECDOTE/author-response, not independent peer review.

**Blake Stacey (physicist), blog, Oct 2023 — still the sharpest written demolition, just before the 24-month core and still the live link.**
- “In Re Vopson’s ‘Mass-Energy-Information Equivalence’ and ‘Infodynamics’,” *Science After Sunclipse*. https://www.sunclipse.org/2023/10/in-re-vopsons-mass-energy-information-equivalence-and-infodynamics/ (also https://www.sunclipse.org/?p=3182)
- Quote: “it is very difficult to provide substantive criticism of a ‘theory’ that has no substance. I could point to individual things that make no sense, but the people who care don’t need my help…” He classifies the media as “press release from the guy who made it up.” **Class:** SERIOUS SPECULATION as expert opinion; not a journal comment.

**Other critiques.**
- r/AskPhysics, Dec 2025 thread “How well regarded is Melvin Vopson?” — community consensus is AIP Advances + press-release physics, not mainstream. https://www.reddit.com/r/AskPhysics/comments/1puz1an/how_well_regarded_is_melvin_vopson/ **Class:** ANECDOTE.
- Matti Pitkänen, TGD diary 2024-01, “Comments about Vopson’s second law of infodynamics” — hostile, but Pitkänen is himself a fringe theorist. https://matpitka.blogspot.com/2024/01/comments-about-vopsons-second-law-of.html **Class:** CRANK-on-crank; do not use as the physicist rebuttal.
- Sf. R. Careaga, Medium, claims a PandaDoc-timestamped critique Vopson ignored. https://medium.com/@careaga.angel/the-limits-of-mainstream-acceptance-a-critical-examination-of-infodynamics-and-the-need-for-open-1a3b84fbf85f **Class:** ANECDOTE.

**I did not find** a 2024–2026 *Physical Review* / *Foundations of Physics* / *Studies in History and Philosophy of Modern Physics* comment on Vopson. The public physicist rebuttal of record is **Hossenfelder’s May 2025 video** plus **Stacey’s 2023 blog**. That absence is itself a finding.

## 3. Blogs / X 2024–2026: noncomputability as a SH refuter

### 3.1 Scott Aaronson — the actual posts (quotes from source)

**29 Jan 2024.** “Does fermion doubling make the universe not a computer?” https://scottaaronson.blog/?p=7705
- Occasion: David Tong’s lecture using the **fermion-doubling problem** as an argument against lattice-simulating the chiral Standard Model (Tong’s lecture: https://www.youtube.com/watch?v=QPMn7SuiHP8 ). Aaronson: Tong “quickly admits that his claim to refute the simulation hypothesis is just ‘clickbait’.”
- Three questions he separates: (1) can known physics be simulated with known methods? (2) is the Physical Church–Turing Thesis true? (3) is our universe a simulation in a larger universe? “As far as I can see, there aren’t even nontrivial implications among them.”
- **The hypercomputation paragraph (exact):**
  > “And conversely: even if Penrose was right, and our laws of physics were Turing-uncomputable—well, if you still want to believe the simulation hypothesis, why not knock yourself out? Why shouldn’t whoever’s simulating us inhabit a universe full of post-Turing hypercomputers, for which the halting problem is mere child’s play?”
  https://scottaaronson.blog/?p=7705
- On fermion doubling as “noncomputable”: “you don’t get to call an aspect of physics ‘noncomputable,’ just because the first method you thought of for simulating it on a computer didn’t work.”
- **Class:** ESTABLISHED as Aaronson’s 2024 position. This is the cleanest 2024–2026 working-CS statement on the question.

**7 Feb 2024.** “On whether we’re living in a simulation.” https://scottaaronson.blog/?p=7774
- MindFest panel with David Chalmers. Repeats the uncomputability point: “Well, why shouldn’t our universe be simulated by a larger universe that also has uncomputable physics, the same as ours does? What, after all, is the halting problem to God?”
- On Penrose–Hameroff: “I get off their train to Weirdville way before it reaches its final stop.”
- On Bostrom-style descendant-sims: he thinks the argument saws off its own branch (sims must be *smaller* than the host).
- **Class:** ESTABLISHED.

Older Aaronson posts (pre-window, still the ones people mean):
- “Because you asked: the Simulation Hypothesis has not been falsified; remains unfalsifiable” (2017). https://www.scottaaronson.com/blog/?p=3482
- “Your yearly dose of is-the-universe-a-simulation” (2017). https://www.scottaaronson.com/blog/?p=3208

I found **no 2024–2026 Shtetl-Optimized post on Faizal/Krauss**. UNCERTAIN whether Aaronson has publicly answered that paper.

### 3.2 Sabine Hossenfelder

**2021 baseline (pre-window, still her position-of-record until 2025):** “The Simulation Hypothesis is Pseudoscience.” https://backreaction.blogspot.com/2021/02/the-simulation-hypothesis-is.html

**11 Nov 2025.** Blog: “Physicists Prove That Universe is not a Simulation.” Teaser: “In a recent paper, a group of physicists say they’ve disproved this theory by using Goedel’s theorem. Let’s take a look.” https://backreaction.blogspot.com/2025/11/physicists-prove-that-universe-is-not.html
- X, 11 Nov 2025: “A group of physicists say they have proved that the universe cannot be a computer simulation. I've had a look at the paper.” Video: https://www.youtube.com/watch?v=k6AddqLIbJA — X: https://x.com/skdh/status/1988275525299712262
- I did **not** fetch a transcript. Given her title style (“Physicists Prove…”) plus 2021 stance, the *likely* video is a takedown, but **UNCERTAIN** without transcript. Do not quote a verdict I did not hear.

**28 May 2025.** Vopson gravity video: https://youtu.be/ArUTSOZcn0E (see §2.3).

**7 Mar 2026.** Blog: “The Simulation Hypothesis Gets Scientific Backing.” Teaser: “Physicists are beginning to explore the consequences of the simulation hypothesis and a computer scientist has proposed a scientific framework to make sense of it.” https://backreaction.blogspot.com/2026/03/the-simulation-hypothesis-gets.html
- X: https://x.com/skdh/status/2030312518015750454 — video https://www.youtube.com/watch?v=UbInSCs47Gw
- The “computer scientist” is **almost certainly Wolpert** (arXiv:2404.16050, v5 Mar 2026). **UNCERTAIN** without the video. Do not claim she reversed her 2021 “pseudoscience” verdict; the teaser only says the question is becoming scientifically discussable.

### 3.3 Peter Shor
X search 2024-01-01 → 2026-09-25 for Shor on noncomputability/SH returned **no matching posts**. **Class:** ESTABLISHED as a null result of this search, not a claim that he never spoke off-X.

### 3.4 X (2025–2026) on Faizal/Gödel
- Dr_Singularity, 31 Oct 2025 (high circulation): “Researchers have mathematically proven that the universe cannot be a computer simulation…” repeating the press line. https://x.com/Dr_Singularity/status/1984395350308741342 **Class:** ANECDOTE (press echo).
- ExploreCosmos_ (astrophysicist-adjacent), 16 Nov 2025: accurate-ish paraphrase of Faizal. https://x.com/ExploreCosmos_/status/1990077214558142967 **Class:** ANECDOTE.
- Rainmaker1973, 14 Dec 2025: long summary citing Krauss on non-algorithmic insight. https://x.com/Rainmaker1973/status/2000260381730582810 **Class:** ANECDOTE.
- Sauers_, 1 Nov 2025: the one serious objection on X (quoted in §1.3). https://x.com/Sauers_/status/1984540973095891036 **Class:** YOUR OWN INFERENCE that this is the correct structural objection; the tweet itself is ANECDOTE.
- Hypercomputation *as a word* did not show up in the X SH discussion in this search.

## 4. “Proven” / “disproven” in 2024–2026 vs what the papers said

### 4.1 Faizal et al. — the big “disproven” wave (Oct–Nov 2025)

**What the paper said:** incompleteness theorems applied to an assumed algorithmic QG ToE ⇒ need “non-algorithmic understanding” ⇒ “any putative simulation … would itself be algorithmic” ⇒ “the universe cannot be a simulation.” https://arxiv.org/abs/2507.22950

**What the press said:**
- UBC Okanagan news, 30 Oct 2025: “new research from UBC Okanagan has mathematically proven this isn’t just unlikely—it’s impossible.” Quote Faizal: “Hence, this universe cannot be a simulation.” Quote Krauss on non-algorithmic understanding. https://news.ok.ubc.ca/2025/10/30/ubco-study-debunks-the-idea-that-the-universe-is-a-computer-simulation/
- phys.org, same talking points: “provides a definitive answer.” https://phys.org/news/2025-10-mathematical-proof-debunks-idea-universe.html
- ScienceDaily 11 Nov 2025: “Physicists prove the Universe isn’t a simulation after all.” https://www.sciencedaily.com/releases/2025/11/251110021052.htm
- Popular Mechanics, Times of India, SciTechDaily, Boing Boing — same headline pattern.

**Gap:** The paper is 13 pages in *Journal of Holography Applications in Physics* (Damghan University). It is **not** a Physical Review Letters experiment and **not** a new Gödel theorem. It applies known incompleteness to a *model of QG-as-formal-system*, then identifies “simulation” with “algorithm.” Aaronson’s 2024 point is the direct counter: a host with hypercomputers, or a non-algorithmic host, is not blocked. **Class of the press claim “proven impossible”:** ANECDOTE (press). **Class of the paper:** SERIOUS SPECULATION.

### 4.2 Vazza — “nearly impossible”

**Paper:** same-physics, high-resolution simulation is energetically impossible; different-physics hosts unconstrained. https://arxiv.org/abs/2504.08461

**Rebuttal (2026):** Eliott Edge & Chad Ashton Brown, “Commentary: Astrophysical constraints…,” *Front. Phys.* 14:1808725 (published 21 Apr 2026). https://doi.org/10.3389/fphy.2026.1808725 — https://www.frontiersin.org/journals/physics/articles/10.3389/fphy.2026.1808725/full
- They argue Vazza attacks a **thicker** target than Bostrom: Bostrom already said “Simulating the entire universe down to the quantum level is obviously infeasible” and only requires verisimilitude of experience. They quote Bostrom FAQ: “Critiques based on the assumption that a simulation would have to be fully comprehensive [e.g., Vazza (2025)] thus miss the point.”
- Popular writeup of that commentary: https://simulism.substack.com/p/physicists-keep-refuting-the-wrong
- Tim Andersen Substack on Vazza: https://timandersen.substack.com/p/the-simulation-hypothesis-may-have
- **Class:** ESTABLISHED that the commentary exists and that Vazza’s strongest conclusion is scoped; whether Bostrom’s thin rendering is *physically* cheaper is a different argument (Argus already has this thread).

### 4.3 Vopson — “supports that we live in a simulation”
Press (Technology Networks, Vice, Sci.News) treated infodynamics as evidence *for* SH. The 2023 paper says the law “appears to underpin” SH. No 2024–2026 result “proves” SH. **Class:** ANECDOTE (press) vs SERIOUS SPECULATION (author’s claim).

### 4.4 Nobody in this window produced a completed lab test that SH is true or false.
Beane, Savage, et al. lattice-anisotropy cosmic-ray test remains **2012/2014** (arXiv:1210.1847; EPJA 2014). https://arxiv.org/abs/1210.1847 — Vazza cites it; I found no 2024–2026 new cosmic-ray anisotropy SH paper.

---

## 5. Claims that a physical process computes something uncomputable (2024–2026)

### 5.1 Faizal et al. 2025 — theoretical, not a machine
They claim *reality contains undecidable truths* and needs “non-algorithmic understanding,” citing Lucas–Penrose. They do **not** exhibit a device that solves the halting problem. https://arxiv.org/html/2507.22950v1 **Class:** SERIOUS SPECULATION (Penrose-line).

### 5.2 Penrose–Hameroff, still live, discussed by Aaronson 2024
Aaronson at MindFest (Feb 2024) records Hameroff/Penrose still holding that Planck-scale uncomputability affects neuronal microtubules and causes consciousness. Aaronson rejects it. https://scottaaronson.blog/?p=7774
Hameroff 2024 still publishing Orch-OR-adjacent claims (e.g. “consciousness came before life,” Hameroff et al. 2024, via Closer to Truth index). https://loc.closertotruth.com/theory/penrose-hameroff-s-orchestrated-objective-reduction
**Class:** SERIOUS SPECULATION historically; mainstream physics treats Orch-OR as **fringe**. Not a 2024–2026 *demonstration* of hypercomputation.

### 5.3 Analog / ARNN hypercomputation
No 2024–2026 experimental paper found. The live literature is still Siegelmann ARNNs, Kieu’s Hilbert-tenth quantum algorithm (long criticized), Malament–Hogarth spacetimes. Wikipedia talk, Oct 2024, is editors arguing the analog-hypercomputation article is “unsalvageable gibberish.” https://en.wikipedia.org/wiki/Talk:Hypercomputation **Class:** CRANK/fringe for “we built one”; SERIOUS SPECULATION for the models.

### 5.4 Null result
I did not find a 2024–2026 claim, crank or otherwise, with a URL, of the form “this physical experiment output a non-Turing-computable function.” If Argus wants cranks in YouTube comments, that is a different scrape. **Class:** ESTABLISHED as search-null, not as proof none exist.

---

## 6. Direct answers to the dispatch questions

| Question | Answer | Best URL |
|---|---|---|
| Who claimed an *empirical test* 2024–2026? | **Vazza 2025** (energy/resolution constraints using UHE neutrinos). **Vopson** (2022 protocol still unrun; 2023 infodynamics as “evidence”; 2025 gravity derivation). Neither is a new lab measurement of a simulator artifact. | https://arxiv.org/abs/2504.08461 ; https://doi.org/10.1063/5.0087175 |
| Anyone linked **noncomputability / hypercomputation** to SH? | **Yes. Faizal–Krauss–Shabir–Marino 2025** argue non-algorithmic reality ⇒ not a simulation. **Aaronson 2024** argues uncomputable physics would *not* refute SH (host hypercomputers). **Wolpert 2024–26** uses PCT as the coupling, Rice/Kleene for simulation structure. | https://arxiv.org/abs/2507.22950 ; https://scottaaronson.blog/?p=7705 ; https://arxiv.org/abs/2404.16050 |
| Has SH been “proven” or “disproven”? | **Press:** Faizal “proved impossible” (Oct 2025). **Paper:** incompleteness + “simulations are algorithmic.” **Vazza:** same-physics full-res sim impossible; different-physics unconstrained. **Edge & Brown 2026:** Vazza missed Bostrom’s thin target. Nobody ran a decisive experiment. | press: https://news.ok.ubc.ca/2025/10/30/ubco-study-debunks-the-idea-that-the-universe-is-a-computer-simulation/ ; paper: https://arxiv.org/abs/2507.22950 |

**For H1-FTC (Argus’s kill condition):** the only 2024–2026 publication that *tries* to turn noncomputability into a SH-falsifier is Faizal et al. It does so by *assuming* the thing H1-FTC would need to *find*. Aaronson’s 2024 posts are the reason that move does not automatically kill even a Turing-host simulation: the host need not be a Turing machine. If the programme is “falsify H1-FTC,” Faizal is a claimed falsifier of *algorithmic* hosts, and Vazza is a claimed falsifier of *same-physics high-resolution* hosts. Neither is an observation of uncomputable physics.

## 7. What this scout did not get to (honest leftover)

- Full PDF line-by-line of Vopson *AIP Advances* 12/13/15 (AIP 403’d the fetch). Abstracts + Portsmouth + Sci.News used instead.
- Transcript of Hossenfelder YouTube k6AddqLIbJA (Faizal) and UbInSCs47Gw (Mar 2026 Wolpert-ish). Verdicts UNCERTAIN.
- Transcript of Hossenfelder Vopson video ArUTSOZcn0E beyond Vopson’s self-excerpt.
- Aaronson on Faizal: no post found.
- Systematic arXiv API dump (title search, not full-text). A paper that never uses the phrase “simulation hypothesis” could have been missed.
- Peter Shor off-X (talks, papers).
- 2026 preprints posted after ~Sep 2025 that Google/Brave ranked poorly.
