The Concept of Revolution in the Sciences: Michael Polanyi's Differences With Thomas Kuhn on Scientific Revolutions

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT Thomas Kuhn's The Structure of Scientific Revolutions (1962) was a blockbuster publication that problematized notions about the origins and nature of scientific revolutions. What became Kuhn's famous rubrics of “normal science” and “paradigms” were similar to concepts of “tacit knowledge” and scientific “frameworks” or “dogmas” in Michael ...

p-Adic and Adelic Cosmology: p-Adic Origin of Dark Energy and Dark Matter

open access: yes, 2006
A brief review of p-adic and adelic cosmology is presented. In particular, p-adic and adelic aspects of gravity, classical cosmology, quantum mechanics, quantum cosmology and the wave function of the universe are considered.

Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...

Phenomenological implications of an alternative Hamiltonian constraint for quantum cosmology

open access: yes, 2005
In this paper we review a model based on loop quantum cosmology that arises from a symmetry reduction of the self dual Plebanski action. In this formulation the symmetry reduction leads to a very simple Hamiltonian constraint that can be quantized ...

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Soft quantum back reaction to the hubble tension: A smeared-out early time cosmological energy density

open access: yesPhysics Letters B
A theoretical explanation for the so-called Hubble tension is provided within the framework of phase-space quantum mechanics extended to (quantum) cosmology.

Equivalence of Models in Loop Quantum Cosmology and Group Field Theory

open access: yesUniverse, 2019
The paradigmatic models often used to highlight cosmological features of loop quantum gravity and group field theory are shown to be equivalent, in the sense that they are different realizations of the same model given by harmonic cosmology.

Alignment of the Starlings: Learning With Generative AI

open access: yesFuture Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT I will argue that answers to normative questions concerning the place of generative AI in learning rest on answers to ontological questions regarding (1) precisely what is happening when a human ‘interacts’ with generative AI and (2) What is distinctive about organic learning as opposed to currently existing ‘machine learning’ (3) What is the ...

Quantum phantom cosmology

open access: yes, 2006
We apply the formalism of quantum cosmology to models containing a phantom field. Three models are discussed explicitly: a toy model, a model with an exponential phantom potential, and a model with phantom field accompanied by a negative cosmological ...
