of the world only began to resemble our modern satellite-imaged, global view of
Earth after the voyages of Christopher Columbus between 1492 and 1504 . Then
observations of the similarities of opposing coastlines led to suggestions,
beginning in 1596, that the continents had been previously joined, but
subsequently broke apart and separated. In 1912, Alfred Wegener presented
compelling evidence and advanced his theory of continental drift, which was
resurrected fifty years later and recast as plate tectonics. But plate tectonics
is problematic, depending critically upon physically-impossible mantle
convection. Ott Christoph Hilgenberg, pictured at right, conceived a
fundamentally different possibility which he published in 1933, image at left,

some earlier time being smaller and without ocean basins. Then, for unknown
reasons the Earth began to expand, fracturing the uniform continental rock crust
and forming interstitial ocean basins.
Hilgenberg's concept became the basis
for Earth expansion theory which offered a different explanation for
geophysical phenomena, but neither were complete theories possessed
problematic elements. Yet both served as stepping stones to a more
fundamental and inclusive geoscience theory, published by J. Marvin
Herndon, which he calls
Whole-Earth Decompression Dynamics and which is a consequence of
Earth's early formation as a Jupiter-like gas giant; for a quick
overview, click here.
Ott Christoph Hilgenberg's concept
stands as one of the most important in the geoscience. Hilgenberg
proposed the only logical, causally-related explanation why the Earth's
surface is composed of two different types of matter, continental rock
and ocean-floor basalt.
