1. Introduction

The state of fundamental theoretical physics in 2026 is paradoxical. On the one hand, there has been remarkable technical progress in several research programs. On the other hand, the field remains conceptually fragmented, with no clear convergence on the deepest questions. Different communities work with different mathematical languages, different notions of what counts as a satisfactory explanation, and different assessments of which problems are fundamental and which are merely technical.

This fragmentation has consequences beyond academia. Public communication of fundamental physics – particularly on platforms such as YouTube and X – is often dominated by oversimplified or sensationalized narratives (e.g., “time does not exist”, “this or that theory has been disproven”). In such an environment, it becomes increasingly valuable to provide clear, honest, and well-referenced assessments of the actual state of research.

The Panvitalist Theory (PVT), developed by the author since 2019, offers a distinctive perspective that differs in several fundamental respects from the dominant programs. The purpose of this paper is to provide a concise but substantive assessment of the current landscape and to locate the PVT within it. The tone is deliberately positioning – the PVT is presented as a serious and in important respects unique alternative – but remains within the bounds of scientific honesty and intellectual modesty regarding the current maturity of the framework.

2. The Current Landscape of Quantum Gravity and Foundations Research (2024–2026)

The following overview orders the major research programs roughly according to their current visibility, institutional presence, and estimated funding levels. The assessment is based on recent conference activity, Simons Collaborations, publication volume in high-impact journals, and the number of active research groups.

2.1 Holographic and Information-Theoretic Approaches

This cluster currently belongs to the most dynamic and well-funded areas. Celestial Holography, in particular, has seen rapid development through the Simons Collaboration on Celestial Holography. Key recent contributions include generalizations of the Connected Wedge Theorem using bulk entanglement wedges (Arayath & Pasterski 2026), the encoding of radiative degrees of freedom via boundary Cotton and stress tensors with a consistent flat-space limit (Ciambelli, Pasterski & Tabor 2024), the construction of multiparticle states from the Carrollian limit (Kulp & Pasterski 2024), and the study of memory correlators and asymptotic charges in the in-in formalism (Moult, Narayanan & Pasterski 2025; Moult, Oertel & Pasterski 2026).

Closely related is the study of quantum complexity in gravity. A major review (Baiguera et al. 2026) synthesizes developments across gravity, quantum field theory, and quantum information, highlighting deep connections between computational complexity and gravitational observables, particularly in the AdS/CFT context. The ER=EPR conjecture, the island rule, and the Python’s Lunch program (May et al. 2025) further illustrate the fruitfulness of information-theoretic ideas in black hole physics.

These approaches benefit from strong institutional support (including dedicated Simons programs) and generate high-visibility results. They are currently among the most active and best-funded directions in the field.

2.2 String Theory and AdS/CFT Extensions

String theory and its holographic dualities remain the largest and most institutionally entrenched research program worldwide. While the original hope of a unique theory of everything has not been realized, the framework continues to produce important results in quantum field theory, condensed matter, and quantum information. Active areas include the Swampland program, de Sitter holography, and attempts to embed the Standard Model more realistically.

Despite persistent criticism – particularly regarding the lack of direct experimental predictions and the difficulty of deriving Standard Model parameters from first principles – string theory retains a dominant position in terms of faculty positions, funding, and graduate training in many leading departments. Recent workshops (e.g., Peking University 2026) demonstrate continued vitality.

2.3 Loop Quantum Gravity and Discrete Approaches

Loop Quantum Gravity (LQG) and its covariant formulation (spin foams) constitute a major non-perturbative, background-independent program. Significant progress has been achieved in black hole entropy calculations, loop quantum cosmology (Big Bounce scenarios), and the development of relational observables. Recent work has also explored elementary dynamical building blocks of the theory (Assanioussi & Livine 2026) and the renormalization flow of spin networks.

LQG maintains a coherent conceptual framework and a dedicated international community. While it generally receives less public attention and funding than holographic or string-theoretic programs, it remains one of the most serious alternatives to the dominant paradigms.

2.4 Relational Quantum Mechanics and Quantum Reference Frames

This program, strongly associated with Carlo Rovelli and a growing group of collaborators (including recent contributions involving Lucien Hardy and others), has gained considerable intellectual influence in the foundations community. The framework of Quantum Reference Frames provides precise operational tools for describing physics from the perspective of quantum systems, offering one of the most sophisticated treatments of the problem of time currently available (Rovelli 2025; Luo 2026; Thiemann 2026).

Although smaller in institutional footprint than the larger programs, relational approaches have produced high-quality conceptual work and are increasingly cited across subfields.

2.5 Other Notable Approaches

Several smaller but conceptually important programs continue to receive attention. Causal Set Theory remains active, with a dedicated Theo Murphy meeting in 2026 focused on its path toward quantum gravity. Emergent and entropic gravity (Verlinde, Jacobson, Padmanabhan) continues to inspire discussion. Newer proposals, such as Jenny Lorraine Nielsen’s Topological Unified Field Theory based on the complex Hopf fibration (Nielsen 2026), offer alternative topological perspectives. Shape Dynamics (Barbour and collaborators) provides a relational, conformal approach to gravity.

These programs are generally smaller in scale but contribute valuable conceptual diversity.

3. Central Open Problems – A Critical Assessment

Despite the diversity of approaches and the impressive technical sophistication of many of them, several deep problems remain unresolved across nearly all programs. More importantly, a closer examination reveals that these problems are not merely technical but point to fundamental conceptual limitations that none of the dominant frameworks has been able to overcome.

3.1 Problems in Holographic and Information-Theoretic Approaches

While Celestial Holography and related programs have produced remarkable technical results, they ultimately rely on a duality between a higher-dimensional bulk and a lower-dimensional boundary. This duality, however elegant, does not resolve the measurement problem, nor does it provide a clear ontological status for the bulk spacetime itself. The computational complexity program (Baiguera et al. 2026) has revealed deep connections between gravity and information, yet it remains unclear whether complexity is a fundamental physical quantity or merely a useful bookkeeping device. The Python’s Lunch conjecture and related cryptographic tests (May et al. 2025) highlight the extreme difficulty of reconstructing bulk information from boundary data – a difficulty that may reflect not just technical complexity, but a deeper mismatch between the assumed holographic structure and physical reality.

3.2 Problems in String Theory and AdS/CFT Extensions

String theory has been the dominant research program for over four decades, yet it has not produced a single falsifiable prediction for particle physics or cosmology. The Swampland program attempts to constrain the landscape of possible vacua, but it remains largely a consistency condition rather than a derivation of observed physics. The difficulty of deriving the Standard Model parameters from first principles persists. Moreover, the very structure of string theory – with its enormous landscape of possible compactifications – raises the question of whether it is a genuine physical theory or a vast mathematical framework that can accommodate almost any observation after the fact. Even within the string community, there is growing recognition that the original promise of a unique theory of everything has not been fulfilled.

3.3 Problems in Loop Quantum Gravity

Loop Quantum Gravity offers a background-independent quantization of general relativity and has achieved notable successes in black hole entropy and loop quantum cosmology. However, the problem of recovering a smooth classical spacetime in the continuum limit remains open. The renormalization flow of spin networks is still poorly understood, and the dynamics at the Planck scale, while discrete, does not yet provide a clear mechanism for the emergence of the observed low-energy physics. Relational observables have been developed, but the problem of time is far from resolved in a way that satisfies all critics. LQG remains a serious contender, yet it has not produced the conceptual breakthrough that would allow it to claim superiority over other approaches.

3.4 Problems in Relational Quantum Mechanics and Quantum Reference Frames

Relational approaches, particularly the framework of Quantum Reference Frames, have provided elegant operational tools for describing physics from different perspectives. They offer one of the most sophisticated treatments of the problem of time currently available. Nevertheless, they ultimately rely on the standard quantum formalism, including its probabilistic interpretation and the measurement problem. By treating all systems as quantum systems, they avoid the need for an external classical observer, but they do not resolve the deeper question of why the world appears classical at macroscopic scales. The relational program is conceptually coherent, yet it remains within the mathematical structure of quantum mechanics without challenging its dimensional or ontological foundations.

3.5 Problems in Other Approaches

Causal Set Theory, emergent gravity, and newer topological proposals each face their own challenges – from the recovery of Lorentz invariance and general relativity at low energies to the derivation of the observed particle spectrum. While they contribute valuable conceptual diversity, none has yet produced a compelling case for being the correct foundation of quantum gravity.

3.6 Synthesis: The Post-1905 Paradigm and Its Limits

When one steps back and surveys the entire landscape, a striking pattern emerges. All major approaches – holographic, string-theoretic, loop-based, relational, or otherwise – ultimately operate within the same post-1905 paradigm: they take the mathematical structures developed in the early 20th century (quantum mechanics, general relativity, gauge theories) as given and attempt to combine, dualize, discretize, or reinterpret them. They refine formalisms, introduce new dualities, impose consistency conditions, or explore mathematical analogies. What they do not do is question the dimensional foundations themselves.

Even some of the most distinguished physicists of the past decades have expressed deep dissatisfaction with this state of affairs. Roger Penrose, Nobel laureate and one of the most original thinkers in gravitational physics, has repeatedly argued that the strategy of “quantizing gravity” is misguided. Instead, he advocates “gravitizing quantum mechanics” – that is, fundamentally modifying quantum theory itself to incorporate gravitational effects at a basic level. Penrose’s twistor theory and his Conformal Cyclic Cosmology represent attempts to rethink the foundations rather than merely combine existing ones.

Gerard ’t Hooft, another Nobel laureate and co-originator of the holographic principle, has pursued the radical idea that quantum mechanics itself may be an effective description of an underlying deterministic, classical theory – the Cellular Automaton Interpretation of Quantum Mechanics. His work reflects a profound discomfort with the non-determinism and non-locality of standard quantum mechanics and a desire to return to a more classical, realist ontology.

Richard Feynman, in the later years of his life, was famously skeptical of string theory, describing it as producing “excuses” rather than predictions. His well-known remark that “nobody understands quantum mechanics” remains as relevant today as it was in the 1960s. Feynman repeatedly emphasized that the foundations of quantum theory were still not truly understood, and he warned against the tendency to accept mathematical consistency as a substitute for physical insight.

These voices from some of the most accomplished physicists of the 20th and early 21st centuries are not peripheral. They point to a deeper malaise: after more than a century of extraordinary mathematical development, the field remains conceptually stuck. The approaches discussed above are rich in sophisticated formalisms, but poor in new physical input at the foundational level. They represent, in essence, mathematical research – the exploration of consistent mathematical structures – rather than physical foundational research in the sense of Planck’s dissatisfaction with the physics behind E = hf in 1900, or Einstein’s radical rethinking of space and time in 1905.

It is against this background that the Panvitalist Theory must be evaluated.

3.7 Dimensionless Unification Attempts – A Revealing Pattern

Interestingly, a growing number of alternative unification proposals outside the mainstream – such as the fractal and golden-ratio-based dimensionless Theory of Everything developed by Stergios Pellis – achieve apparent mathematical unification of quantum mechanics and general relativity precisely by abandoning dimensional consistency or setting all constants to unity. While these attempts are generally not considered physically rigorous, their very existence and relative success in producing elegant formalisms reveal a deeper truth: the unification problem appears far less intractable once the constraints of dimensional analysis are removed.

This pattern strongly suggests that the persistent difficulties in reconciling QT and GRT are not primarily mathematical, but rooted in the dimensional structure of standard physics itself – a structure built upon dimensionless constants (such as π = C/d), an external time parameter, and the postulate c = constant. The Panvitalist Theory addresses exactly this root cause by redefining dimensions in a physically motivated way (π ≡ T/L, rational volume comparisons, six-dimensional anisotropic volumes). In this sense, the PVT does not merely offer another mathematical refinement, but corrects the dimensional foundations that make unification artificially difficult in the first place.

4. The Panvitalist Theory: Core Features and Distinctive Characteristics

The Panvitalist Theory rests on three axioms and a single dynamical law:

1. Dimensioned curvature: π ≡ T/L (time as internal angular curvature, not an external parameter).
2. Six-dimensional anisotropic volumes, with three lengths and three angles as dynamical degrees of freedom.
3. Rational measurement: only comparisons V_A = x V_B with x ∈ ℚ are physically meaningful.

The sole dynamical constraint is volume preservation: δV = 0.

From these minimal assumptions, both General Relativity (in the orthogonal limit) and Quantum Theory (as a timeless constraint problem) emerge naturally.

The theory is distinguished by several features. We separate these into two categories for clarity.

4.1 Individually Unique Features

To the best of the author’s knowledge, the following features are not pursued in this specific form by any other current approach in quantum gravity or the foundations of physics:

• The redefinition of π as a dimensioned quantity (π ≡ T/L), treating time as internal angular curvature within volumes rather than an external parameter.
• The incorporation of a “living universe” at the axiomatic level, with angles as dynamical degrees of freedom that reflect internal activity and choice.
• An explicit physical-mathematical model of free will at two levels: the observer’s freedom to choose internal reference angles for measurement, and the fundamental unpredictability of the universe’s external behavior.
• A radical de-mathematization, systematically removing complex numbers, the imaginary unit, and Gödel-incomplete formalisms in favor of a complete, geometrically intuitive, and fully calculable mathematics based solely on rational 6D volumes.

Given the conceptual simplicity and elegance of the relation π ≡ T/L, the author would not be surprised – and indeed rather expects – if this idea is independently rediscovered or quietly adopted by others in the coming years. History shows that the most powerful foundational insights often spread precisely because they are so simple.

4.2 Features Unique in This Specific Combination

In addition, the PVT combines several further elements in a way that, to the best of the author’s knowledge, does not appear together in any other current framework:

• Modeling the act of measurement as primary, rather than assuming an objective reality independent of the observer.
• Providing a genuine solution to the problem of time by recognizing time as real, yet only partially modelable due to its nature as internal curvature.
• Generalizing Einstein’s theories by replacing the postulate “c = constant” with the deeper geometric principle “1/π = constant” (rational curvature).

This combination of individually distinctive features and synergistic elements positions the Panvitalist Theory as a fundamentally different approach to the foundations of physics – one that addresses several persistent problems of contemporary programs from a genuinely new foundational angle.

5. Positioning the PVT within the Current Landscape

The PVT differs from the dominant programs in several fundamental respects. Unlike most holographic approaches, it does not postulate a bulk-boundary duality but derives holographic phenomena as natural projections of 6D volume dynamics. Unlike most relational approaches, it does not treat time as purely relational or emergent from clocks, but as internal curvature within volumes. Unlike LQG, it does not introduce fundamental Planck-scale discreteness but enforces rationality at the level of measurement comparisons.

These differences are not merely technical. They reflect a different foundational philosophy: the PVT begins with the act of measurement and builds outward, rather than postulating an objective spacetime or gauge structure and then attempting to quantize or dualize it.

Crucially, the PVT does not merely offer another mathematical refinement within the post-1905 paradigm. It returns to the spirit of genuine physical foundational research that characterized the period from Planck’s 1900 hypothesis to Einstein’s 1905 special relativity. By challenging the dimensionless nature of π and the external status of time at the dimensional level, it proposes a conceptual shift that has the potential to overthrow a century-old paradigm. This is not mathematical cosmetics; it is a fundamental re-examination of the categories with which physics describes the world.

While the PVT is still at an earlier stage of technical development than some of the established programs, its conceptual minimalism, internal consistency, and unique combination of features – including its willingness to question what others take as given – make it a serious candidate that addresses several persistent problems from a genuinely different angle.

6. Conclusion and Outlook

The current state of theoretical physics is characterized by impressive technical achievements within several competing frameworks, yet also by a lack of convergence on the deepest foundational questions. The dominant approaches, for all their sophistication, remain largely within a paradigm of mathematical exploration that has not produced the conceptual breakthrough needed to resolve the most persistent problems. Even voices as distinguished as those of Penrose, ’t Hooft, and Feynman have expressed profound dissatisfaction with the current state of affairs.

The Panvitalist Theory provides a different kind of perspective. By modeling measurement rather than assumed reality, by replacing dimensionless constants with dimensioned geometric quantities, and by embedding life and free will at the axiomatic level, it opens a path that is distinct from the major programs currently dominating the field. It represents not another step in the mathematical refinement of existing structures, but a return to the kind of bold conceptual rethinking that characterized the foundational breakthroughs of 1900–1905.

Whether this path ultimately leads to a successful unification remains to be seen. However, its conceptual clarity, minimalism, and unique combination of features constitute a valuable and, in important respects, unprecedented contribution to the ongoing debate. In a field that has become increasingly dominated by mathematical formalisms, the PVT dares to ask whether the foundations themselves need to be re-examined at the most basic level – the level of dimensions, measurement, and the nature of time and space.

Future work will include detailed comparisons with Celestial Holography and Relational Quantum Mechanics, as well as the derivation of specific observational signatures from the δV = 0 constraint.
