Is this the first glimpse of dark matter?

A single data point from a dark-matter detector in the United States could be the first discovery of the elusive particle we call dark matter. The LUX-ZEPLIN experiment at the Sanford Underground Research Facility in South Dakota contains 10 tonnes of liquid xenon. It seeks evidence of a candidate particle called a WIMP (weakly interacting massive particle) by looking for flashes created when such a particle collides with the nucleus of just one xenon atom. If the finding can be backed up with more data, it could mean that the material that seems to make up most of the mass of the Universe has finally been discovered.

Physicists home in on mysterious ‘glueballs’

A team of physicists says it has observed strong evidence of a mysterious ‘glueball’, a particle made up of force-carrying gluons. The team says that a particle known as X(2370) is mostly made up of these glueballs — clusters of the gluons that bind quarks to form protons and neutrons and hold them inside the nucleus of an atom. There is no single smoking gun that proves that this particle is made of glueballs, says particle physicist Bruce Yabsley. But the findings are “quite persuasive”, he says. The group presented their results at the International Conference on High Energy Physics in Natal, Brazil, last week.

Underdog ‘spin qubits’ leap forward in race to a useful quantum computer

Four independent research teams have reported big advances in the design of quantum devices that rely on ‘spin qubits’ to encode information. Spin qubits are made by carving precise patterns into semiconductor wafers, forming wells that can hold a single electron. In the race to create a useful quantum computer, this design had previously not been considered a front-runner, because systems that used spin qubits were small and had high error rates. The new systems range from 5 to 18 qubits, and one has slashed the error rate to less than 0.01%.

The first ticking ‘nuclear clocks’ are here

Two research teams, one in Europe and one in China, have made the world’s first ‘nuclear’ clocks. These clocks derive their ‘tick’ from the energy that makes protons and neutrons inside the nucleus of thorium-229 shift to a higher energy level. The groups used similar approaches to solve the problem that’s hindered nuclear-clock development in the past: how to keep the clock’s tick speed from drifting over time. Creating a nuclear clock is “a dream come true”, says atomic physicist Thorsten Schumm, a member of the European team. “Now we have a fierce but friendly global competition.”

JUNO finds clues to neutrino-mass mystery

Researchers working on the Jiangmen Underground Neutrino Observatory (JUNO) experiment in Guangdong, China, have captured crucial details of how mysterious neutrino particles can switch between different types in flight. Neutrinos are so light that they were once thought to have no mass, and the standard model of particle physics doesn’t seem to explain why they do. Physicists use experiments such as JUNO to study how neutrinos ‘oscillate’, or change from one type to another, which is the first step in answering that question.

The exotic particles that could finally break the Standard Model

Physicists know that their elegant theoretical description of forces and particles — the Standard Model — must be incomplete, because there are a host of phenomena it cannot explain. But observations continue to confirm the model’s accuracy with ever greater precision. Thank goodness an analysis from an experiment at the Large Hadron Collider at CERN, Europe’s particle physics laboratory, suggests at least one way out: the decay of particles called B meson. A new analysis found that the angle at which the final products emerge from the decay disagree with those predicted by the Standard Model. Evidence for this anomaly has been growing since 2015.

Quantum simulations verified by experiments for the first time

For the first time, physicists have matched detailed quantum-computer simulations to experimental data gathered from work with solid materials. Two teams of physicists achieved the feat independently: one simulated the physical properties of a magnetic material, such as its heat capacity, and the other modelled a different material’s response to being excited into a range of energy states. Both agreed with experimental data.

‘Nuclear clocks’ tick closer to reality

After decades of research, physicists are confident that the first tick of a ‘nuclear clock’ is imminent. This device would keep time by measuring energy transitions in the radioactive isotope thorium-229, which could make it the most precise clock on the planet. Last week, scientists at the American Physical Society Global Physics Summit compared notes on their progress toward assembling the clock’s components, including efforts to build a laser that can make the clock ‘tick’.

Schrödinger’s cat just got bigger: quantum physicists create largest ever ‘superposition’

In the iconic quantum double-slit experiment, a photon acts like a wave and interferes with itself — illustrating the mind-boggling concept that particles can exist in a ‘superposition’ of possible locations at once. But just how big can such a quantum object be? At least as big as a blob of around 7,000 sodium atoms, it turns out. Using a painstakingly constructed experimental set-up, researchers managed to observe tell-tale interference patterns for sodium clusters some 8 nanometres wide, with superpositions that stretched across 133 nanometres. The clusters are as big as some viruses, raising the tantalising possibility of putting biological matter through the same experimental set-up.

Blogger Comments:

This is an impressive and painstaking experiment. Demonstrating clear interference patterns for clusters of around 7,000 atoms, spatially separated by more than 100 nanometres, represents a real extension of the regimes in which quantum descriptions can be experimentally sustained. As experimental control of isolation, coherence, and interferometric precision, the work deserves genuine admiration.

What is worth handling carefully, however, is how such results are often presented.

When articles speak of objects “existing in a superposition of locations at once”, or frame the experiment as probing whether quantum mechanics “still applies” at larger scales, a subtle shift occurs. Formal features of a successful theoretical description begin to be treated as literal claims about what the system is, rather than about how it can be described under tightly controlled conditions.

From a more structural perspective, a superposition is not an ontological state of affairs. It is a theoretical potential: a space of possible outcomes defined relative to a particular experimental arrangement. The interferometer does not reveal a sodium cluster to be “in many places”; it actualises a phenomenon whose meaning is inseparable from the construal that makes it observable.

Seen this way, the familiar question — “where does the quantum world give way to the classical?” — is slightly misplaced. What changes is not the world itself, but the stability of the conditions under which certain descriptions remain coherent. Quantum mechanics does not abruptly fail at larger scales; rather, it becomes progressively harder to maintain the isolation and precision required for quantum descriptions to remain usable.

The real achievement of experiments like this is therefore not that they show ever-larger objects to be “really” quantum, but that they map how far we can extend a powerful theoretical construal before the practical conditions that sustain it dissolve.

Does gravity produce quantum weirdness?

Theoretical physicists Richard Howl and Joseph Aziz have put forward a controversial proposal on whether gravity is quantum in nature: gravity could have quantum effects without itself being a quantum theory. Previous work has suggested that if two quantum objects can be ‘entangled’ through their mutual gravitational attraction, then that attraction — and therefore gravity itself — should be of quantum nature. Aziz and Howl say that an interaction of two masses also occurs in fields other than gravitational, such as the electron field, which could generate entanglement with gravity’s indirect involvement.

Blogger Comments:

Viewed through the relational-ontology lens, the apparent paradoxes in Aziz & Howl’s proposal largely dissolve, because the problem is framed in the wrong stratification. Let me unpack this carefully.

---

1. Behaviour versus ontology

The “problem” arises in conventional terms:

Entanglement arises ⇒ gravity must be quantum.

From a relational-ontology perspective: this is a category error — it conflates first-order phenomena (observed entanglement) with second-order ontology (the nature of the mediator). Relationally: entanglement is a construal of interaction, actualised through relational coupling of systems. It does not compel a claim about the intrinsic register of gravity.

---

2. The mediator as relational field

Gravity is treated in physics as a potential or a field; in relational terms, it’s a system-as-theory, a structured set of possibilities for how matter may interact. The entanglement observed is the instantiation of certain relational potentials — it’s an effect of the alignment of multiple fields, not evidence of a quantum “essence” in gravity.

---

3. Scaling and context

Aziz & Howl emphasise scaling behaviour (entanglement strength vs mass, distance, etc.). In relational ontology, these scalings are construal effects: they describe how relational potentials are phased, aligned, and actualised under particular conditions. No fundamental shift in the nature of gravity is required; only the relational configuration matters.

---

4. Why the “dilemma” disappears

• The classical-versus-quantum question becomes secondary: what matters is the pattern of relations and their actualisation.

• Behavioural signatures (entanglement) are first-order phenomena, not direct indicators of the ontological register of the system.

• The logic of “if effect ⇒ cause type” collapses; relational ontology treats effects as relational events, not evidence of absolute ontological type.

---

5. Metaphorical resonance for symbolic systems

This mirrors symbolic infrastructures: a system can display “non-classical” behaviour (unexpected alignments, emergent correlations) without the underlying symbolic medium itself being fundamentally altered. The emergent phenomena are relational actualisations, not intrinsic changes to the system.

---

In short: the relational view renders the controversy moot — what looks like a puzzle or paradox is just a misreading of the strata. Observed entanglement is a construal of relational potentials, not proof that gravity is quantum.

Weird ‘time crystals’ are made visible at last

Using liquid crystals — bar-shaped molecules with properties between those of a liquid and those of a solid — researchers have created a time crystal, a form of matter that shows continuous, repeating patterns over time, that is visible with the naked eye. Simply by shining a light on the liquid crystals, the team created ripples of twisting molecules through them. The ripples kept moving for hours, undulating with a distinct beat, even when the researchers changed the conditions. The rhythm was also out of sync with any incoming force — fulfilling the two defining criteria for a time crystal.

Unifying gravity and quantum theory requires better understanding of time

How is measuring a quantum state evolving in Hilbert space similar to the ‘Pick Up Song’ game in the long-running British comedy radio show, I’m Sorry I Haven’t a Clue? Glad you asked: theoretical physicist Fay Dowker tells us the answer en route to explaining why the theories of gravity and quantum physics are so fiendishly difficult to reconcile.

Blogger Comments:

I see several layers of metaphorical and ontological slippage in this Nature piece. Some are familiar (old metaphors recycled), others are subtler and specific to this framing of Hilbert space, synchronised time, and Feynman’s histories. Let me outline some key candidates for critique:

---

1. Against Time as a Shared Metronome

The article describes the “perfect synchronisation” of Hilbert-space time and physical 3D time, even invoking a comic analogy with a song and a singer. This reifies time as a background metronome ticking identically in two separate “worlds,” Hilbert space and physical space.

Relationally, this is a category error: time is not a substance that can be synchronised across ontological domains but a symbolic ordering principle constructed within each framework. To imagine one “t” flowing identically in two incompatible spaces instals Newton’s ghost back into quantum mechanics.

---

2. Against Hilbert Space as a Place

The Copenhagen “duality of location” is described as if Hilbert space were a literal arena — a shadowy stage where “things happen” that then interface with 3D events. This is a spatial metaphor smuggled onto an abstract probability structure. Treating Hilbert space as a quasi-physical location risks collapsing the symbolic into the ontological, confusing mathematical scaffolding with reality’s furniture. Relationally, Hilbert space is not a “where” but a representational device encoding potential relational patterns.

---

3. Against Gravity as a Dynamical Actor

The article presents space-time as “both stage and actor” in “reality’s play.” This theatrical metaphor suggests space-time has agency or substance. But this is still background metaphysics, just dressed in dynamical clothing: space-time becomes “the thing that is everything.” Relationally, this risks hypostatising a symbolic construction. Space-time, like Hilbert space, is a model — a symbolic weave that allows us to order and predict phenomena, not an ultimate fabric.

---

4. Against Histories as Ontological Facts

Feynman’s sum-over-histories approach is described through the metaphor of “possible histories” of events like rain in Bengaluru. This frames histories as ontologically real alternatives, as if the world were constantly branching into detailed factual tapestries. But histories are not metaphysical scrolls lying in wait; they are symbolic constructs that structure potentialities. Confusing them for “what really might have happened” conflates representation with ontology.

---

5. Against the Illusion of Conceptual Closure

The article ends by celebrating Sorkin’s cosmological constant prediction as vindication of the sum-over-histories approach. Yet it slides from pragmatic predictive success to ontological endorsement: the method “must be right” because it produced the right number. Relationally, success stabilises a symbolic architecture — it does not reveal the essence of being. This conflation of predictive utility with metaphysical truth is one of physics’ most persistent illusions.

---

6. Against the Repetition of “Strangeness”

Even after adopting Feynman’s histories to remove the “strange duality of location,” the author insists that “the strangeness must be there somewhere.” This rhetoric naturalises the expectation that quantum mechanics must be weird — as if weirdness were an ontological property rather than a symptom of mismatched symbolic frames. The insistence on “quantum strangeness” entrenches the classical as normal and renders quantum a permanent anomaly, obscuring the possibility that both are just different cuts.

---

📌 Overall:

The essay reproduces the very metaphysical traps it claims to escape. Time is treated as a synchronisable universal flow, Hilbert space as a place, space-time as an actor, histories as ontological, and strangeness as a property of reality. What disappears is the reflexive insight: all of these are symbolic constructions whose power lies in their pragmatic alignment, not in their metaphysical essence.

Double-slit experiment with one-atom slits

Researchers have fine-tuned one of the most iconic experiments in physics — the double-slit experiment — using two single atoms as the slits. A photon fired at the atoms is scattered in a version of the familiar pattern that has graced a thousand physics textbooks: ripples of interference in some conditions (in this case, when the atoms were trapped in well-defined positions) or no interference (when they were not). The experiment once again shows how light behaves as both a particle and a wave, while negating some of the concerns about experimental ‘noise’ that worried Albert Einstein. “I think this is a beautiful experiment and a testament to how far our experimental control has come,” says physicist Thomas Hird. “This probably far surpasses what Einstein could have imagined possible.”

Blogger Comments:

This experiment takes the double-slit experiment to a whole new level. Instead of using ordinary slits, researchers used two individual atoms as the “slits” for photons of light. The results are as beautiful as they are revealing.

Quantum Possibilities, Not Fixed Properties

Photons are usually described as either particles or waves. But this experiment shows that a photon doesn’t carry a fixed identity. Its behaviour depends on the quantum system it interacts with—here, the positions of the two atoms.

• When the atoms are well-positioned, the photon creates the familiar interference pattern, like ripples from overlapping waves.

• When the atoms are uncertain or wobbly, the pattern disappears, and photons behave more like individual particles.

This tells us that quantum phenomena are context-dependent: what you see depends on how the system is arranged.

Every Detection is an Event

Each photon’s arrival on the detector is a moment of actualisation. The interference pattern doesn’t exist in any single photon—it emerges from the collective behaviour of many photons interacting with the atomic system.

Think of it like a flock of birds: a single bird doesn’t create the wave patterns you see in flight, but the flock as a whole does. Similarly, the interference pattern is a manifestation of the system’s underlying potential.

Why This Matters

• The experiment shows that quantum properties are not intrinsic; they emerge from relationships between objects.

• It demonstrates how modern technology can probe quantum potential directly, giving us a cleaner, more precise view than ever before.

• Most importantly, it reminds us that the world at the quantum level is emergent, relational, and profoundly context-sensitive—things only “appear” in the way they do because of the configuration of the system.

In short: the photon is neither strictly a particle nor a wave—it is potential made actual by the system it meets, and the pattern of outcomes is a collective story told by many such interactions.

Six physicists debunk six quantum myths

• Quantum physicist Maria Violaris explains that scientists haven’t managed to send particles back in time — yet.
• Quantum-computing researcher Estelle Inack says that it’s one thing to have a quantum computer, but another to extract the right answer for a complex calculation out of it.
• Theoretical physicist Sabine Hossenfelder recounts that Albert Einstein didn’t reject the concept of entanglement as ‘spooky action at a distance’.
• Physicist Norma Sanchez believes that the two grand theories of general relativity and quantum physics can be reconciled — and is working on a type of quantum space-time that might do the job.
• Quantum computing won’t break all encryption — probably — says theoretical computer scientist Shweta Agrawal.
• There’s not yet one, perfect interpretation of what quantum mechanics says about the nature of reality, says physicist and philosopher Emily Adlam. We’re still “waiting for the stroke of inspiration that might open our eyes to the truth”.

Blogger Comments:

1. “Scientists haven’t managed to send particles back in time — yet.”

Here, the joke is in the “yet.” What’s at play ontologically is the assumption that “particles” exist as things-in-themselves that could be displaced backwards along a timeline. But in relational ontology, “time” is not an absolute container. It’s a construal — a dimension of alignment across events. So asking whether particles can “go back in time” misconstrues both “particles” and “time” as entities rather than perspectives cut from experience.

---

2. “It’s one thing to have a quantum computer, but another to extract the right answer…”

Here we see the practical recognition that “quantum potential” is not neatly convertible into determinate results. This is exactly what we’d say: the system of potential is not the same as its actualisation. The “answer” doesn’t pre-exist in the quantum system — it emerges in the cut from potential to actual. The difficulty is not “extracting” but construing in a way that stabilises meaning across that cut.

---

3. “Einstein didn’t reject entanglement as spooky action at a distance.”

This is a correction of a popular myth, but even the correction is framed within a realist metaphysics. Entanglement, for us, is nothing “spooky” because it’s simply the reflexivity of construal across separated instances: the system defines what counts as separation. Einstein resisted because he wanted a determinate system behind construal; but if construal is constitutive, there is no “behind.”

---

4. “GR and QM can be reconciled by quantum space-time.”

This is the old quest for unification at the theory level. From our standpoint, the reconciliation is already obvious: both are different ways of construing reflexive alignment — one across motion, one across possibility. A “quantum spacetime” model is another construal, but it doesn’t solve the “ontological” problem unless one accepts that construal is the ontological ground. Otherwise it’s just another patch.

---

5. “Quantum computing won’t break all encryption — probably.”

This shows the danger of reifying potential as omnipotent. The assumption is that quantum = limitless power. But as we’ve said, potential is not actuality. The actual is always cut through construal, which places constraints and boundaries. So encryption may well survive because reflexive constraints cannot be bypassed by sheer possibility.

---

6. “There’s not yet a perfect interpretation of quantum mechanics.”

Here the game is revealed. The search for a “perfect interpretation” is a metaphysical quest for the reality behind construal. But if construal is reality, then there can never be such a final interpretation. Instead, interpretations are alternate construals of the same reflexive ground. The “stroke of inspiration” will not reveal “the truth” but a shift in how truth itself is construed.

---

Overall:
This list is an excellent little cultural text. Each item both reproduces and strains against the metaphysical assumptions of mainstream physics. And our relational ontology lets us see that the “myths” themselves are just failed construals — attempts to stabilise meaning in ways that exceed the limits of the cut.

AI helps assemble ‘brain’ of future quantum computer

A team has used an artificial intelligence (AI) model to calculate the best way to rapidly assemble ‘neutral atom arrays’ — a grid of atoms that might one day serve as the ‘brain’ of a quantum computer. One of the big challenges in using arrays of atoms for quantum computing is working out how to rearrange them in an “efficient, fast and scalable manner”, says physicist and study co-author Jian-Wei Pan. AI solved that problem for the team — and did it quickly.

Tiny device only needs the Sun to lift off

A device takes advantage of the properties of two layers of material to levitate using only the power of sunlight. The top layer is transparent, allowing sunlight to shine through it, and the bottom layer absorbs that sunlight. Gas molecules moving from the cold transparent layer to the hot bottom layer creates a lift that is similar to that created by a helicopter’s whirring rotor, says engineer Igor Bargatin, who has pioneered work on similar devices.

A new dawn for quantum-gravity research

Despite years of trying to create a quantum theory of gravity, researchers haven’t generated any concrete evidence to support any one contender. Now experiments are in the works that could finally test the true nature of gravity in the laboratory. Some tests plan to use advanced lasers still being invented. Others require ambitious techniques to manipulate matter that might never be achievable. Still, after years of stagnation, some physicists are welcoming “a new era in quantum-gravity research”, says theorist Jonathan Oppenheim.

Blogger Comments:

1. Category Error: Treating Systems as Objects

The article consistently speaks as if “gravity” and “quantum mechanics” are things in the world with inherent natures, awaiting discovery.
From our standpoint, both are systemic theories — structured potentials for phenomena.
The question “Is gravity quantum?” assumes there is an ontological essence to be located, rather than acknowledging that the two are incommensurable construals until a new symbolic cut integrates them.

Effect: The discourse conceals the constructive nature of scientific integration, presenting it as passive observation.

---

2. Obfuscation of the Cut

Every experimental proposal described is, in fact, a cut — a perspectival act that co-instantiates selected aspects of the two systems.
Yet the article frames these as tests of reality, implying that the phenomena are there regardless of the observer’s symbolic choices.

Effect: This hides the reflexive role of experiment in making the phenomenon it claims to measure.

---

3. Reflexive Blindness

The narrative positions experiments as neutral, theory-independent arbiters. In practice:

• The choice of measurable quantity,

• The instrumentation design,

• The interpretive framework,
  …are all symbolic alignments that already presuppose a particular outcome space.

Effect: The article does not interrogate how these alignments predetermine what counts as “evidence” for quantum gravity.

---

4. Slippage Between Phenomena and Metaphenomena

The piece oscillates between describing experimental setups (first-order phenomena) and making claims about the nature of reality (second-order metaphenomena) without marking the shift.
For example:

• “If we see X, gravity must be quantum” is a metaphenomenal statement.

• “We will measure Y in the lab” is a phenomenal statement.
  The lack of distinction lets the metaphenomenal claim pass as though it were an empirical description.

Effect: The reader is led to conflate empirical events with theoretical commitments.

---

5. Erasure of Institutional Context

The drive toward tabletop “quantum gravity” experiments is not purely intellectual — it is shaped by:

• Funding landscapes favouring small-scale, rapid-turnaround science

• Prestige incentives for cross-domain breakthroughs

• The narrative appeal of “solving” physics’ biggest question in a lab setting
  Yet the article treats this as if it were an unmediated trajectory of scientific progress.

Effect: This depoliticises the phenomenon and erases the collective construal processes shaping the research.

---

6. Illusion of Ontological Finality

The conclusion implies that once an experiment “confirms” gravity’s quantum nature, the ontological question will be settled.
From our view, such a result would simply instantiate a new symbolic architecture for physics — one whose stability would depend on continued alignment across theory, experiment, and institutional acceptance.

Effect: It presents scientific closure where there is, in fact, only a momentary stabilisation of meaning.

---

Overall Assessment

The Nature article participates in the mainstream physics discourse that:

• Treats symbolic systems as if they were the world itself,

• Treats perspectival cuts as neutral acts of measurement,

• And elides the reflexive, constructive nature of theory–experiment integration.

A relational ontology reading recasts the story not as “closing in on nature’s answer,” but as actively building a shared symbolic frame in which “gravity” and “quantum” can coexist without contradiction — a frame that does not yet exist, and whose creation will be as much a social and semiotic process as a technical one.

What does quantum physics mean anyway?

First sketched out a century ago, the equations at the heart of quantum mechanics underpin technologies from computer chips to medical-imaging machines. But no one seems to agree on how best to describe the physical reality that lies behind the maths. A Nature survey of more than 1,100 researchers — the largest ever on the subject — has revealed just how widely researchers vary in their interpretations of the most fundamental features of quantum experiments, and their confidence in their answers.

Blogger Comments:

The Nature survey highlights a familiar but unresolved paradox: the most precise and successful theory in modern physics—quantum mechanics—still lacks a shared interpretation of what it means. Is the wavefunction real? Is quantum theory about particles, probabilities, information, or something else? After a century of extraordinary predictive power, physicists still disagree on whether the theory describes reality or merely models outcomes.

From the perspective of relational ontology, this confusion isn’t surprising. In fact, it’s precisely what we’d expect when modern physics is still working within metaphysical assumptions that quantum theory itself has already undermined.

Here are four key reframings:

---

1. There is no “quantum world”—because there is no unconstrued world.

The debate assumes there’s a physical reality “out there” that quantum theory either does or does not describe. But relational ontology begins from a different starting point: phenomena are not things but construed events. A theory like quantum mechanics isn’t a mirror of a pre-existing world—it’s a structured potential for construal. The quantum wavefunction isn’t a “real object” or “just information”—it’s a system, a theory of possible instances, awaiting a perspectival cut.

---

2. The observer–observed divide is not a mystery—it’s a misconstrual.

Quantum puzzles often hinge on the observer’s role in measurement. Does the observer collapse the wavefunction? What happens when no one is watching?

These questions presuppose a dualism between subject and object, knower and known. But relational ontology treats this distinction not as an ontological given, but as a cut within the system. The observer and observed are co-constituted in the act of construal. Measurement is not epistemic interference—it is actualisation within a potential.

---

3. Wavefunction “reality” is a category mistake.

Physicists in the survey disagree on whether the wavefunction is real. But this assumes that “reality” is a simple category—either you exist or you don’t.

Relational ontology makes a sharper distinction: structured potentials are not actual entities, but neither are they fictions. The wavefunction belongs to the realm of system—a theoretical space of possibility. Its instantiation—what physicists call a measurement—is a perspectival shift, not a metaphysical transformation.

---

4. Meaning precedes measurement.

Quantum experiments don’t generate raw data that later acquires meaning—they produce phenomena only through construal. The apparatus, the observable, the notion of “collapse”—these are not neutral or passive. They are symbolic selections within a semiotic system. The meaning of quantum events is not discovered but enacted.

---

In sum: the survey reveals not just disagreement, but the limits of the metaphysical frame in which these debates are taking place. As long as quantum theory is interpreted through a lens that separates reality from construal, observer from observed, and theory from meaning, confusion will persist.

Relational ontology doesn’t offer another interpretation of quantum mechanics. It offers a reorientation: from what the theory says about the world to how the world arises in and through construal.

Tunnelling ramps up quantum weirdness

A “tour de force” experiment has revealed yet another mind-bending outcome of quantum physics. Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy. The counter-intuitive result contributes to a long-standing debate about how to define tunnelling time, for which there is no single description, and how fast the process occurs.

A quantum tunnelling experiment. Quantum tunnelling allows quantum particles to travel into regions of space, called barriers, that would be forbidden by classical physics. Sharoglazova et al. measured the speed of photons tunnelling into a barrier. The experiment took place in a dye-filled cavity between two mirrors. The bottom mirror was nanostructured to create two ‘waveguides’ that directed the light. In the primary waveguide, photons were generated by shining a laser at fluorescent dye molecules. This waveguide formed a ramp that gave the photons potential energy. The photons travelled down the ramp until they encountered a barrier. When they tunnelled into the barrier, they also tunnelled sideways into the secondary waveguide. The rate at which the photons hopped between the two waveguides was used to measure the speed of the particles in the barrier.

Relational Reflections on Quantum Tunnelling

This latest experiment may appear to ramp up the “weirdness” of quantum physics — but what if the real issue lies not in the phenomena themselves, but in the metaphors we use to describe them?

Rather than imagining particles skipping through barriers, a relational view reframes the situation more fundamentally:

• No particle is passing through a wall. What’s happening is a transformation within a field of relational potential, shaped by constraints. The waveguides and mirrors don’t guide a thing; they structure a space of possible transitions.

• Tunnelling speed isn’t the velocity of a substance but the rate of actualisation — how quickly a new configuration emerges under constraint. In this view, energy is not the fuel of motion but a factor shaping the system’s internal tensions.

• The so-called “barrier” is not an obstacle being overcome. It’s a zone of reduced affordance — a relational bottleneck that nonetheless permits transformation under the right systemic conditions.

This reframing also sheds light on why the experiment challenges Bohmian mechanics, which assumes particles have definite positions and rest in infinite barriers. In relational terms, that assumption already misses the point: what’s unfolding isn’t a trajectory but a redistribution of coherence — a reorganisation of potential under dynamic constraint.

So perhaps what appears as “quantum weirdness” is better understood as a symptom of ontological mismatch: we’re trying to describe relational phenomena using object-based metaphors. Recasting the scene in terms of fields, constraints, and systemic transformation lets the mystery breathe differently.

In this light, tunnelling isn't a particle doing the impossible. It's the field adjusting itself — meaning isn’t skipping the barrier; it’s flowing around it.

‘Minimalist’ quantum computer simulates movements of molecules

A single atom has performed the first full quantum simulations of how certain molecules react to light. Researchers simulated the behaviour of three different organic molecules when they are hit with an energetic particle called a photon. They encoded these different parameters into a single ytterbium ion trapped in a vacuum using pulsating electric fields. The minimalistic approach could dramatically speed the path towards a ‘quantum advantage’, says the team behind the feat.
