New Theories in Astronomy

In Short

Written by a Scottish civil engineer and published posthumously, this book presents a revisionist reading of celestial mechanics and nebular evolution. The author scrutinizes contemporary models of gravity, planet formation, and solar dynamics, arguing that standard calculations misapply physical laws. By calculating densities, contraction rates, and gravitational balances, he contends that matter naturally redistributes outward during condensation, leaving hollow centers in planets and stars alike. The text moves systematically from critiquing mine-shaft gravity tests to detailing the thermal history of the solar system, asserting that physical engineering principles offer a more logical universe than abstract mathematical consensus.

The Story

The argument begins with an critique of contemporary observational methods and theoretical foundations. Examining famous experiments designed to weigh the Earth—specifically Sir George Airy’s pendulum measurements inside the Harton colliery—the text asserts that mainstream astronomers have misapplied the law of attraction. Rather than gravity pulling equally from all directions toward a solid core, physical principles dictate that attraction operates differently inside a sphere. The book maintains that standard text-books uncritically accept the premise that attraction inside a hollow shell equals zero, ignoring how real particles respond to local mass and inverse-square distances.

Expanding from local experiments to cosmic origins, the text evaluates prevailing cosmological models. It reviews ancient concepts alongside modern nebular hypotheses proposed by Laplace, Faye, Croll, and Braun. The author subjects M. Faye’s chaotic vortex model to rigorous numerical scrutiny, demonstrating contradictions in its assumed densities, space volumes, and rotational dynamics. To illustrate the extreme tenuity proposed by these theories, the author translates abstract cosmic matter into tangible figures, comparing densities to exact ratios of grains of mass per thousands of cubic feet.

The core of the work builds an alternative quantitative model of the solar system’s evolution. Step by step, the author traces the original contracting nebula as it sheds successive rings to form the planets, calculating remaining volumes, densities, and equivalent temperatures from Neptune inward to the Sun. At each stage, the text computes the precise dimensions, cross-sectional areas, and condensation rates of the planetary rings, arguing that contracting matter does not require pre-existing extraneous heat crammed into the original gas. Instead, friction, condensation, and localized consolidation create the necessary thermal energy for molten liquid globes.

This cosmological framework directly informs a new theory of planetary interiors. Applying structural stress mechanics and density limits derived from the crushing strains of real materials, the text rejects the idea of a solid or entirely liquid interior for the Earth. Instead, as the primitive earth-moon gas cloud condensed, the vastly greater mass at the exterior pulled internal particles outward, creating a hollow center. The Earth is modeled as a hollow shell with its region of maximum density located 817 miles beneath the surface, sustained by opposing gravitational forces and superincumbent weight.

Finally, the book extends this hollow-shell model to the Sun and stellar mechanics. The Sun is described as a gasiform body whose internal activity is driven by vast subterranean churning. Phenomena such as sun-spots and solar prominences are explained not as surface combustion, but as internal eruptions where churned matter escapes through shell apertures. Ether is framed as a continuous material medium responsible for transmitting gravitational strain instantly across space, providing a physical mechanism for action at a distance.

How It Unfolds

Critique of standard measures The book examines early density experiments, targeting pendulum readings in deep mines to show how current gravitational theories fail when applied inside a physical body.

Evaluation of nebular hypotheses The author analyzes competing models of planetary creation, calculating exact space-to-mass ratios to prove that existing chaos and vortex theories contain mathematical contradictions.

Tracking cosmic condensation Using detailed arithmetic, the narrative follows the shrinking solar nebula, computing the precise thickness, density, and temperature of each planetary ring dropped during contraction.

Modeling hollow planets The text details how gravitational forces act on a gas mass, arguing that outer particles draw inner ones outward to form a hollow sphere with a central shell of maximum density.

Explaining solar dynamics Applying the hollow-shell concept to the Sun, the author accounts for sun-spots and jet prominences through internal churning and the relief of physical pressure through deep vents.

Defining the medium of gravity The conclusion frames universal ether as an interconnected substance under strain, providing a mechanical explanation for gravitational pull between distant worlds.

The People

Sir George Biddell Airy The Astronomer Royal whose mine-shaft pendulum experiments at Harton colliery are directly challenged. His theoretical conclusions regarding Earth's density are presented as flawed applications of the law of attraction that text-books accept without proper scrutiny.

Hervé Faye The French astronomer whose cosmological model, detailed in L'Origine du Monde, is subjected to numerical breakdown. His reliance on chaotic vortices is shown to be self-contradictory regarding density and rotational physics.

Lord Kelvin (Sir William Thomson) The prominent physicist whose calculations on the sun's age and thermal limits are referenced. His estimates on the geological lifespan of solar heat serve as benchmarks for testing the author's own evolutionary timelines.

The Civil Engineer (The Author) The driving intellectual presence behind the text, who brings practical expertise in structural mechanics, material crushing strains, and railway design to evaluate cosmic phenomena through straightforward physical logic.

In Its Own Voice

"Left to ourselves we can only liken the process to that followed by a man who peels off the outer layer of an onion, eats the interior part, and when he is satisfied throws down the outer layer and thinks no more of it..."

The author uses a homely comparison to criticize theoretical models that ignore what happens to matter inside a hollow spherical shell during gravitational calculations.

"We have no reason for supposing that an enormous supply of extraneous heat was crammed into each nebula, merely to be radiated into space before condensation could take place..."

This observation highlights the book's insistence on physical efficiency and conservation of energy during planetary ring formation.

"In like manner an alteration in strain between the sun and the earth... connected by an indiarubber ether will be felt instantly in both bodies..."

Here the author presents a mechanical analogy to explain how gravitational attraction operates directly through a continuous physical medium.

What It's Really About

Beneath its mathematical calculations, the book is a defense of practical engineering logic against abstract theoretical physics. It challenges the authority of academic consensus, arguing that mathematical models must answer to physical common sense and known material behavior. By investigating how gravity behaves within a body rather than just outside it, the work seeks to eliminate absurdities—such as infinite densities or wasted cosmic heat—from astronomical theory. It champions a universe governed by structural balance, mechanical efficiency, and consistent physical laws, where planets and stars form stable, hollow structures rather than dense, impossibly compressed spheres.

Why Read It Today

This work offers an engaging window into nineteenth-century alternative science, written not by a mystic, but by a seasoned infrastructure engineer applying structural mechanics to the heavens. Readers interested in the history of science will appreciate the author's meticulous, arithmetic-heavy approach to dismantling the scientific orthodoxies of his day.

The reading experience is characterized by plainspoken confidence, patient step-by-step calculations, and a dry, quiet wit. The author writes with clear, direct prose, though modern readers must navigate lengthy numerical breakdowns, old-style measurement units, and extensive textual tables. While its central premise of hollow planets sits entirely outside modern astrophysical consensus, the book remains a fascinating artifact of Victorian scientific debate. It demonstrates how a dedicated technical mind, working outside academic institutions, attempted to reconstruct the universe using a pencil, a slide-rule, and practical physical intuition.
