A Philosophical Approach to MOND: Assessing the Milgromian Research Program in Cosmology
Dark matter is a fundamental component of the standard cosmological model, but in spite of four decades of increasingly sensitive searches, no-one has yet detected a single dark-matter particle in…
A Comment on ‘Cosmology and Convention’ by David Merritt
- PhysicsJournal for General Philosophy of Science
In a recent article Merritt (2017) has claimed that current observational data provide “severe tests” falsifying the standard cosmological model (the Lambda-Cold-Dark-Matter model). Based on Popper’s…
Problems with the dark matter and dark energy hypotheses, and alternative ideas
- PhysicsThe multi-messenger astronomy: gamma-ray bursts, search for electromagnetic counterparts to neutrino events and gravitational waves. Proceedings of the International Conference.
Two exotic elements have been introduced into the standard cosmological model: non-baryonic dark matter and dark energy. The success in converting a hypothesis into a solid theory depends strongly on…

MOND and Methodology
- BiologyKarl Popper's Science and Philosophy
It is argued that a comparison of the two theories of cosmology in terms of their ‘truthlikeness’ or ‘verisimilitude’ is essentially impossible since the two groups of scientists achieve correspondence with the facts in often very very diﬀerent ways, and it is suggested that a better guide to the theories’ progress toward truth might be the methodologies themselves.
A new model of the universe based on the transition along a straight line
- PhysicsJOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES
Cosmological observations show that the cosmos has almost flat space geometry and is located in a spatial expansion phase. The accelerated expansion of the cosmology has been proven by the observable…
String theory, Einstein, and the identity of physics: Theory assessment in absence of the empirical
Proposal for a Degree of Scientificity in Cosmology
- PhysicsFoundations of Science
In spite of successful tests, the standard cosmological model, the $$\varLambda$$ Λ CDM model, possesses the most problematic concept: the initial singularity, also known as the big bang. In this…
Screams for explanation: finetuning and naturalness in the foundations of physics
It is explained why the necessity to define a probability distribution renders arguments from naturalness internally contradictory, and why it is conceptually questionable to single out assumptions about dimensionless parameters from among a host of other assumptions.

THE FAILURES OF THE STANDARD MODEL OF COSMOLOGY REQUIRE A NEW PARADIGM
Cosmological models that invoke warm or cold dark matter cannot explain observed regularities in the properties of dwarf galaxies, their highly anisotropic spatial distributions, nor the correlation…
Alternatives to Dark Matter (
It has long been known that Newtonian dynamics applied to the visible matter in galaxies and clusters does not correctly describe the dynamics of those systems. While this is generally taken as…
Novel test of modified Newtonian dynamics with gas rich galaxies.
- PhysicsPhysical review letters
A test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals is reported.
Avoiding dark energy with 1/r modifications of gravity
Scalar quintessence seems epicyclic because one can choose the potential to reproduce any cosmology (I review the construction) and because the properties of this scalar seem to raise more questions…
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
- PhysicsLiving reviews in relativity
It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units.
A tale of two paradigms: the mutual incommensurability of ΛCDM and MOND
The concordance model of cosmology, ΛCDM, provides a satisfactory description of the evolution of the universe and the growth of large-scale structure. Despite considerable effort, this model does…

Confronting Lemaitre–Tolman–Bondi models with observational cosmology
The possibility that we live in a special place in the universe, close to the centre of a large void, seems an appealing alternative to the prevailing interpretation of the acceleration of the…
Introduction to Cosmology
The standard big bang cosmological model and the history of the early universe according to the grand unified theories of strong, weak and electromagnetic interactions are summarized. The…
A test of the Copernican principle.
- PhysicsPhysical review letters
The blackbody nature of the cosmic microwave background (CMB) radiation spectrum is used in a modern test of the Copernican principle, and limits on spectral distortions are shown to exclude the largest voids which mimic cosmic acceleration.
