Vladimir S. Netchitailo is a physicist and independent cosmological researcher, and the author of the World-Universe Model (WUM), also referred to as the Hypersphere World-Universe Model or World-Universe Cosmology (WUC). A laser physicist by training, Netchitailo developed an interest in cosmology and has elaborated the World-Universe Model over many years, uploading his first papers on viXra in 2013 and subsequently publishing a series of articles in the Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC). He presents the model as an alternative to the standard Big Bang cosmology.

Biography

Netchitailo's professional background is in laser physics. In his papers he describes roughly five decades of work in physics and, in a 2021 retrospective preprint titled 20 Years in Cosmology, dates his sustained cosmological research to the early 2000s. The affiliation given on his published papers is Biolase Inc. in California (given variously as Irvine and Cromwell in different articles), a company working in laser technology.

He began posting his cosmological work publicly on the viXra preprint archive in November 2013, and by 2026 had accumulated more than sixty preprints there. In parallel he has published a long series of peer-reviewed articles in the Journal of High Energy Physics, Gravitation and Cosmology from 2015 onward, developing the model in successive instalments — first as the "5D World-Universe Model," later reformulated as the "Hypersphere World-Universe Model," and most recently presented under the name "World-Universe Cosmology."

Netchitailo has presented his work extensively to the natural philosophy community, giving a multi-part lecture series on the Hypersphere World-Universe Model in the CNPS online seminar and livestream programme during 2024, with further presentations in 2025 and 2026, and additional talks in the Cosmology discussion sessions hosted on Roger J Anderton's YouTube channel.

Scientific contributions

The World-Universe Model

The World-Universe Model is proposed by Netchitailo as a unified framework intended to describe the origin, evolution, structure, and parameters of what he terms the "World," in contrast to the Big Bang Model. Its principal advantage, as he presents it, is that it does away with both the initial singularity and inflation, which he regards as artefacts of the standard model rather than physical descriptions.

According to WUM, the World is a 3-dimensional hypersphere on the surface of a 4-dimensional "Nucleus of the World," a 4D ball that expands in a fourth spatial dimension. Netchitailo bases the model on the assumption that the World is finite and boundless, and expands inside a surrounding "Universe" at a speed equal to the electrodynamic constant c, with the Universe acting as an unlimited source of energy that continuously enters the World across its boundary. Matter is therefore created continuously — a process he likens to sublimation from the expanding surface of the 4-ball nucleus — rather than all at once in a primordial event. In this picture space and time are emergent phenomena, dependent on matter and on the Medium rather than existing as a pre-given stage.

Medium of the World

The model is built around the concept of a "Medium of the World" (or Cosmic Medium) composed of massive particles: protons, electrons, photons, neutrinos, and dark matter particles. Netchitailo holds that there is no empty space in the World; the Medium fills it everywhere, and its energy density is the quantity to which gravitation is ultimately connected. Photons in the Medium are treated as having a small non-zero rest mass. From the properties of the Medium the model derives values for such quantities as the Hubble parameter, the temperature of the microwave background radiation, and the parameters of the intergalactic plasma, which Netchitailo compares with measured values.

Two fundamental parameters

Netchitailo holds that two fundamental parameters, expressed in various rational exponents, determine the macro and micro features of the World: the fine-structure constant α ≈ 1/137, which is constant, and a dimensionless quantity Q, which increases with time and serves as a measure of the size and age of the World (currently of order 1040). A distinctive consequence is that the gravitational parameter G is not a true constant but a derived quantity that decreases as the World expands, scaling inversely with Q. The model provides a mathematical framework intended to tie together a number of fundamental constants and to allow their values to be calculated directly rather than measured and inserted by hand. The age of the World in WUM is about 14.2 billion years.

Multicomponent dark matter

WUM proposes a multicomponent dark matter system with weak self-interaction, predicting five types of dark matter particle together with their masses: neutralinos (≈1.3 TeV), WIMPs (≈9.6 GeV), DIRACs (≈70 MeV), ELOPs (≈340 keV), and sterile neutrinos (≈3.7 keV). Their energy densities are related to the proton energy density by successive powers of α. Netchitailo argues that the self-annihilation of these particles leaves observable signatures in gamma-ray spectra, and he has devoted a review specifically to cosmic gamma rays around 70 MeV as evidence for DIRACs. He further proposes a "Macroobject Shell Model," in which superclusters, galaxies, stars, and extrasolar systems all possess dark matter cores surrounded by shells of differing particle composition.

Angular momentum, the Dark Epoch and macroobject formation

Netchitailo places particular emphasis on the angular-momentum problem in the formation and evolution of galaxies and extrasolar systems, and argues that WUM is the only cosmological model consistent with the law of conservation of angular momentum. He divides the history of the World into a Dark Epoch, spanning roughly the first 0.45 billion years, during which only dark matter macroobjects existed in the Medium, and a Luminous Epoch covering the subsequent ~13.77 billion years, in which luminous matter emerged through dark matter particle self-annihilation. Influx of dark matter particles supplied both mass and angular momentum to supercluster cores until they became "overspinning" — surface speed exceeding escape velocity — at which point he proposes an Explosive Volcanic Rotational Fission Model to account for the transition to the Luminous Epoch and for the transfer of angular momentum to satellite objects. In this scheme macroobject size, mass, and rotational angular momentum grow with cosmological time as τ1/2, τ3/2, and τ2 respectively. He has argued that observations by the James Webb Space Telescope of unexpectedly mature early galaxies support this account.

Applications to astrophysics and geophysics

In later work Netchitailo has applied WUM to a wide range of specific phenomena: the structure of the Milky Way and Andromeda, observations of the Galactic Centre by NASA and the Event Horizon Telescope Collaboration, and the Fermi Bubbles; the mysteries of the Solar System, including the retrograde rotation of Venus, the axial tilt of Uranus, the heating of the solar corona, the origin of the Moon, and the composition of the giant planets; the internal structure and heating of the Earth, including a layer at the 660 km boundary he names "Geomagma," the Expanding Earth, the Faint Young Sun paradox, and random variation in the length of the day; and high-energy atmospheric physics, in which terrestrial gamma-ray flashes are interpreted as gamma-ray bursts, lightning initiation is attributed to gamma-ray bursts carving conductive paths through thunderclouds, and the Tunguska event is attributed to the atmospheric explosion of a superbolide. He has also addressed ball lightning within this framework.

Hubble tension and the Patchwork Quilt

Netchitailo's most recent work addresses the Hubble tension — the discrepancy between locally measured and early-universe-inferred values of the Hubble constant. Where the Big Bang Model assumes a practically infinite, homogeneous, and isotropic universe expanding from an initial singularity, World-Universe Cosmology envisions the finite, boundless observable World as a "Patchwork Quilt" composed of some 103 or more luminous superclusters that formed independently, in different regions and at different cosmological times. On this view the differing measured expansion rates are not a contradiction to be reconciled but a direct signature of that patchwork structure. Related recent papers cover magnetism in World-Universe Cosmology, the establishment of physical constants and parameters within the framework, four-spatial-dimension formulations, and an argument for a Solar System origin of the interstellar object 3I/ATLAS.
