Terrestrial Expansion
The terrestrial expansion is a theory trying to explain the position and the movement of the Continent S on the surface of the Ground, affirming that this one grows bigger since its formation, about a few millimetres to 10 cm per annum.
This theory was a source of polemics and it was occulted by the Plate tectonics . The majority of the Geologist S or the Geophysicist S which supports the theory at present are in favor of the Australian geologist S. Warren Carey.
History of the theory
Gravitational constancy
The idea of a Ground expanding appeared in science towards 1938, when the physicist Paul Dirac (1902-1984) suggested that the gravitational constant of the Earth had decreased since its billion years of existence. That led the German physicist Pascual Jordan to a modification of general relativity to propose into 1964 that all the planets grew bigger slowly. Jordan thought that the Earth could have doubled ray in the last hundreds of million years.That could thus explain the massive size of the Dinosaure S, which would have profited from a less Pesanteur.
Impact of the Neutrino S
Konstantin Meyl presented in 2004 a bond between the expansion and the absorption of the neutrinos of the Earth.
Criticisms of the theory
The majority of the polemics confronting the theories of the expansion and the plate tectonics are centered around the validation of the model of the Subduction. The subduction is the process by which (in the theory of the plate tectonics) the material of the Earth's crust disappears in the coat, allowing planet to preserve its size.The partisans of the model of the Earth expanding argue on the lack of evidence of the existence of the subduction. In particular due to the fact that the oceanic faults at the bottom of the oceans are much broader than the known zones of subduction. In addition, the ocean floor has a regular surface, without irregularity which would indicate the existence of a subduction which would leave a oceanic clogging of crust.
