La teoría de las placas tectónicas es un mito, y no es porque yo lo diga, el geólogo australiano Dr. James Maxlow lo explica en esta conferencia. Esta es la primera parte (la conferencia entera consta de 14 partes):

Segun James Maxlow cual es la causa de la expansión de la tierra?

What is causing the Earth to expand?
The entire question as to where the additional mass comes from to explain an increase in Earth radius is a very important core issue to Expansion Tectonics, but a very difficult question to answer. Because the Earth has always been considered the same size since creation; from either a cosmological or religious point of view, it has not been necessary to ask this question. Because the question has not been asked, or taken seriously, where the additional mass comes from remains speculative.

Since the theory of Earth expansion was first proposed in the late 1890s, five main re-occurring themes for the cause of Earth expansion have been suggested. These can be summarized as:

1. A pulsating Earth, where cyclic expansion of the Earth is said to have opened the oceans and contractions have caused orogenesis (mountain building). This proposal fails to satisfy exponential expansion, as shown by modern oceanic mapping, and Professor Carey considered the theme to have arisen from the false misconception that mountain building implies crustal contraction. In addition, Carey saw no compelling evidence for intermittent contractions of the Earth.
2. Meteoric and asteroid accretion. This is currently a popular theory, proposed also to explain some of the various extinction events that have plagued the Earth. It basically says expansion is caused by an accumulation of extraterrestrial debris over time. This theme was rejected by Carey as the primary cause of Earth expansion, since expansion should then decrease exponentially with time, not increase as shown by the oceanic mapping. Nor does it explain ocean floor spreading, or the distribution of oceanic crust or covering sediments.
3. Constant Earth mass, with phase changes of an originally super-dense core. This was again rejected by Carey as the main cause of Earth expansion because the theme implied too large a surface gravity throughout the Precambrian to Late Paleozoic Eras. A large Precambrian surface gravity was not evident from studies carried out during the 1970s. For a constant Earth mass, density would have also been unacceptably high during the Precambrian.
4. Secular reduction of the universal gravitation constant G. Such a decline of G was said to cause expansion through the release of elastic compressional energy throughout the Earth, and phase changes to lower densities in the mantle. Carey rejected this proposal as the main cause of expansion for three reasons: (a) formerly the surface gravity would have been unacceptably high, (b) the magnitude of expansion is probably too small, and (c) the arguments for such a reduction in G were considered not to indicate an exponential rate of increase in radius.
5. A cosmological cause involving a secular increase in the mass of the Earth. This suggestion remains the most popular theme.


Where the required excess mass came from was considered at length by Professor Carey. Knowing Einstein’s equation E=mc2 implies that matter and energy are inter-convertible. Matter is therefore the antithesis of energy where matter is created from energy and vise versa. Carey further considered that new mass added to the Earth must appear deep within the core. But, he also considered the ultimate cause of Earth expansion must be sought in the cosmological expansion and complementary generation of new matter processes within the entire Universe.

The proposed causal model for Expansion Tectonics, while still largely speculative, involves an increase in mass by condensation, or segregation of new matter from energy within the Earths core. This new matter accumulates at the core-mantle interface and the increase in volume results in swelling of the mantle. Mantle swell is then manifested in the outer crust as crustal extension and is currently occurring as extension along the mid-ocean-rift zones. Matter generation within the Earths core is seen as an endothermic reaction, which will ultimately result in a decay of matter formation in the core and cessation of expansion with time.
