The preceding evidence of Earth’s growth by accretion of extraterrestrial matter and accelerating expansion made it obvious to me that our planet was not rapidly created 4.5-4.6 Ga (billion years ago) in its present size, shape, volume and chemical composition as decreed by the Kant-Laplace Nebular Hypothesis, nor as recounted in Genesis in the Bible. 

With this realization it became clear that a new theory of Earth's creation was needed, one that would agree with the slow planetary growth process garnered in my research on expansion of the planet.  The conclusion was simple; the process itself amounted to a new cosmological theory of creation of the Earth and Solar System I named simply ACCREATION (creation by accretion) because that is the way the planet was formed.  (The theory also should be applicable to all planetary bodies in our Solar System and other galaxies in the Universe. ) 

Therefore, the current belief must be nullified and replaced by an entirely new theory of Earth’s creation, one based on a cometary nucleus orbiting the Sun slowly enlarged by gravitational accretion of extraterrestrial matter until it reached spherical shape, at which point gravity could omni-directionally focus total weight of the protoplanet on its exact center. 

From this point forward, gravity began to generate immense gravitational pressure that heated and melted originally cold proto-planetary rock to form a molten core that is constantly expanding, thereby creating irresistible tectonic force that fractured the planet’s outer shell and eventually extruded magma, minerals, gases, and H2O from volcanoes, and midocean ridges later, to initiate formation of an atmosphere and hydrosphere. 

This core melting and expansion process is the dynamic mechanism that expanded and gradually elevated all surface areas radially outward from the planet’s center— which is best exemplified by the Antarctic continent expanding southward AWAY from all other continents.

The constant external accretion of meteoric material increased Earth’s gravitational constant as it gradually increased Earth’s mass and total surface area, and the melting process decreased Earth’s density as the molten core steadily grew larger and rapidly expanded the planet.


A key discovery in developing this new Accreation Theory came in 1987 from listing most of the larger known bodies in the Solar System by size. [See list below]  This list produced an illuminating fact—all smaller solar bodies appear to be irregularly-shaped, but as diameters reach ~400-600 km (~250-375 mi), they become nearly spherical, and ALL ARE SPHERICAL by the time they reach a diameter of ~940 km (~585 mi).  

This discovery led me to conclude that all bodies in the Solar System must be created by the same accreation process, whether comet, meteoroid, asteroid, planet or Sun—their only real differences being size, shape, and compositional variety provided by newly-arrived supernovae fragments (comets) and meteor flux from different galactic sources.

This discovery also led me to conclude that gravity is the primary force responsible for the spherical shape of all planetary bodies.  After an irregularly-shaped proto-planetary body reaches spherical shape by slow external accretion of mass, the total gravitational pressure of its mass (weight) can be focused omnidirectionally on its exact center, causing compressive heating of originally cold central core material and a phase change to molten magma that expands, creating tectonic pressure that must either explode the planet or rupture its confining outer shell.

The immense tectonic force of the expanding magma eventually finds, or creates, crustal weaknesses that develop into surface grabens, fractures, or volcanoes that temporarily relieve the tectonic pressure.  In this respect, volcanoes are planetary safety valves.  Volcanoes also recycle core magma onto existing surface areas and thereby add to the planet’s diameter.

The expanding molten core feeds on its confining outer shell, gradually melting its way outward towards the crust by melting away the underbelly of mantle layers surrounding it.  The melting process distills from the solid rock the H2O and other gases that are eventually transported to the surface to commence formation of surface water and an atmosphere.

Earth’s atmosphere gradually increases in density and thickness with the passage of time and causes greater ablation of all meteors, creating more dust particles and reducing the sizes of impacting meteorites.

In later stages of development when large bodies of surface water and oceans have formed, crustal expansion fractures known as midocean ridges (MOR), (actually linear underwater volcanoes (LUV)), create new oceanic seafloor by spreading magma to either, or both, sides of the MOR.  The pressure and magma flow frequently creates underwater mountains (seamounts) that may rise above sea level and become islands.  In this process, extruded magma generates new seafloor that widens the ocean basins and increases the planet’s total surface area—further increasing Earth’s diameter.

MOR hydrothermal vents (“black smoker vents”) also bring to the seafloor virgin new H2O, gases, and minerals distilled from proto-planetary rocks that melted to become core magma.  This new H2O increases the total volume in the oceans, and the gases are either combined in solution with seawater or are released into the atmosphere, but mineral deposits deposited on the ocean bottom are subsequently covered by accretion of sediments consisting of dust (terrestrial and meteoric) and organic detritus from marine fauna and flora.  


Global growth and expansion are the result of external accretion of extra-terrestrial dust and meteorites, and internal expansion of the molten core.  These basic growth and expansion mechanisms slowly increase the mass and diameter of the Earth.  They can be broken down further and summed up as the product of five physical processes, all of them currently active:

+  Passive daily accretion of mass from extraterrestrial meteorites and dust.  This was the only source of planetary growth until the proto-planet reached spherical shape.

+  Dynamic core expansion due to gravitationally-generated compressive heating and phase change of originally cold solid matter to molten magma after the proto-planet reached spherical shape.  The tectonic force of expanding magma is now the primary mechanism of expansion, and greatly exceeds the slow external growth rate of surface accretion of mass.

+  Magma extrusion via volcanoes and midocean ridges creates new continental crust and oceanic seafloor that increases the planet’s total surface area and diameter.

+  Emission of virgin H2O, gases and minerals via terrestrial volcanoes that gradually generated an atmosphere and hydrosphere, and via underwater hydrothermal vents ("black smoker vents") that filled the expanding ocean basins.

+  Solar insolation of additional mass by photosynthesis after H2O and organic life emerged on the planet.
