Expansion of the Earth

 Expansion of the Earth

    Did the planet Earth remained with the same radius from the beginning of its formation? Here's an intriguing question and the answer to this question certainly  promotes strong impact on geological knowledge. The Theory of Plate Tectonics was an important advance in understanding the planet, but   would be correct all the propositions of this theory?

   It may be noted that there is no question about Continental Drift and, therefore, the continents move, but will the proposals on subduction zones would be valid? The processes of formation of mountain chains were linked to areas of convergence - or the results would be buckling surface by the processes of expansion?

  The expansion of the Earth or the Earth Expanding Theory had as one of its most important proponents , Australian geologist Samuel Warren Carey (1911-2002). He and a small number of other researchers, continued to support expansion and investigate models of the Earth. Carey coined such phrases as "Subduction is a myth," "The most likely site for error is the most fundamental of our beliefs" and "Subduction exists only in the minds of its creators" In fact, it may be noted that there is a much greater extent of linear kilometers of Mid-ocean ridge, where there is clearly expansion of the ocean floor, than linear kilometers of so-called subduction zones as suggest by the paradigm of Plate Tectonics.

  The artist Neal Adams is also a supporter and promoter of ideas about a new model of the universe and the Earth Expanding Theory. According to this theory, both Earth and other celestial bodies expand. There would not exist the supercontinent Pangea and the so-called subduction zones. Neal Adams has established a YouTube channel with videos produced by himself, offering his vision of expanding the models of planet Earth.

  Current models of the Earth's interior, based on studies of seismology and mantle tomography indicate that the mantle is rigid and colder than previously thought. How could then occur subduction zones? Another fact to consider is that everything in the universe seems to expand. The observation of the planets of the solar system does not show any suggestion that subduction zones could occur, however expansion processes seem to play an important role in the evolution of planets and stars. Why only planet Earth work within the meaning of Plate Tectonics?

  It may be noted that there are so many questions to be resolved and that support at least in the field of logic. Expansion models allow almost perfect adjustment of the continental masses on a planet with a radius smaller than the current one. Note also that many models of continental reconstruction based on Plate Tectonics leads to many inconsistencies, and that will be if that used a smaller radius in reconstruction adjustments would be better?

  It would be very interesting to try to reconstruct all the continents according to the Expanding Earth Theory, using available data  from geochronology, geological and paleontological correlation. If there is a better fit, certainly part of the Plate Tectonics Theory should be reviewed, analyzed and reviewed. Perhaps the most important challenge in this new global tectonics would be to study the causes of possible mechanism of expansion and adjustment of mountain building in the geologic time.

  1. Earth is not expanding now. But the planet experienced considerable expansion during the past geological periods when its mantle was semi-fluid. Before expansion - when the earth was small and covered by a single granitic super-continent, there were no oceans. Hence, at that stage, when owing to association of large quantum of water the planet's mantle was considerably fluid and suitable for expansion, the phenomenon of expansion took place owing to gravitational pull of a planetary body, probably the Moon. Due to expansion cracks were developed over the crust through which molten magma associated with volatiles and ocean forming water extruded. In subsequent periods when the mantle turned into a solid and rigid body due to escape of volatiles and water, further expansion was stopped. ( EARTH - THE PLANET EXTRAORDINARY, Subhasis Sen, Allied Publishers, New Delhi, India, 2007, p 232).

  2. Nasa did a study a few years and concluded that in the period they measured the Earth that it is not expanding. If you measure my height and compared it with my height 5 years ago you might conclude that I too am not growing and therefore I have always been my current height and I was born 5'7".

    1. Very good analogy dear Hawaiianian!
