Cosmology as it is usually studied suffers from the problem that no criterion is known which isolates from the large class of models allowed by the equations of physics those few which are realized in Nature. To provide such a criterion, it is proposed that cosmology should be based on the study of models which are free of arbitrary scales or units, this condition being compatible with (but not identical with) the Cosmological Principle. Formally, the basis for scale-free cosmology can be… 

Similarity Criteria, Galactic Scales, and Spectra

An old topic of dimensional analysis in astrophysics is presented and new results, or quantitative explanations of some observational facts are obtained, in particular, on the base of the supernova,

It has been a long-standing goal in physics to present a physical model that may be used to describe and correlate the physical constants. We demonstrate, this is achieved by describing phenomena in

We Begin with a “Trivial” Condition on Massive Gravitons, and Use That to Examine Nonsingular Starts to Inflation, for GW, with GW Strength and Possible Polarization States?

Our Methodology is to construct using a “trivial” solution to massive gravitons, and a nonsingular start for expansion of the universe. Our methodology has many unintended consequences, not the least

Constraining the Existence of Magnetic Monopoles by Dirac-Dual Electric Charge Renormalization Effect Under the Planck Scale Limit

It was suggested by dimensional analysis that there exists a limit called the Planck energy scale coming close to which the gravitational effects of physical processes would inflate and struggle for

Quantum Gravity Effects in Scalar, Vector and Tensor Field Propagation

Quantum theory of gravity deals with the physics of the gravitational field at Planck length scale (10−35 m). Even though it is experimentally hard to reach the Planck length scale, one can look for

Dimensional fundamental constants and their application in astronomy

A discussion is given of the role of dimensional fundamental constants in gravitational and particle physics. It is concluded that such constants can most usefully be interpreted as representing

Paul Wesson and Space-Time-Matter Theory

A short scientific biography is given of physicist Paul Wesson (1949-2015), who published over 300 works encompassing the fields of astrobiology, astrophysics, geophysics, cosmology, and relativity;

Measurement Quantization Unites Classical and Quantum Physics

Unifying quantum and classical physics has proved difficult as their postulates are conflicting. Using the notion of counts of the fundamental measures—length, mass, and time—a unifying description

A Constant Rotating Kerr-Newman Black Hole with No Net Electrical Charge

A black hole solution for the rotating electrical charge gives the Kerr-Newman metric. Incorporation of the oscillating effects show to drive rotation. The model derived permits the consideration of

Are Borders Inside or Outside?

When a boat disappears over the horizon, does a distant observer detect the last moment in which the boat is visible, or the first moment in which the boat is not visible? This apparently ludicrous



The cosmological constant and cosmological change

Is the Universe of infinite extent, or is it a finite system? Will it expand forever, or will it reach some maximum size before turning and collapsing upon itself like an inverse Big Bang? Just a few

The case for a hierarchical cosmology.

Once upon a time philosophers and cosmographers insisted that the motions of the planets must be circular and uniform. An irrelevant aesthetic concept of ‘perfection’ and a more valid mathematical

Self-similar space-times

The equations of general relativity are reduced to a set of simultaneous ordinary differential equations in one dimensionless variable by an appeal to self-similar symmetry. Analytic solutions are

Accelerating Universe revisited

THERE is growing evidence that the Hubble constant is of the order of 100 km s−1 Mpc−1, rather than only half as great1. The purpose of this paper is to discuss the Friedman models that are

Dynamic measurement of matter creation

IF a rotor could be spun so that it had an inertial decay time ∼ 1011 yr, 1018 s, it could test matter creation cosmologies1–3 at a significant level. The advantage of this method over previous

Recent progress in gauge theories of the weak, electromagnetic and strong interactions

~ Note: This review is based in part on a talk given at the II' Conference Internationale d'Mix-en-Provence sur les Particules Elementaires, September 6, 1973. A preliminary version of this review is


The nonrandom clustering of galaxies and clusters of galaxies has attracted increasing attention in the past 40 years. The mathematical tests and criteria used to distinguish between an observed

The new frontier of particle physics

Quarks and leptons have emerged as elementary constituents of matter. To these may perhaps be added the field particles, or mediating agents, of a unified theory of the weak and electromagnetic

An accelerating Universe

New data on the Hubble diagram, combined with constraints on the density of the Universe and the ages of galaxies, suggest that the most plausible cosmological models have a positive cosmological
