Pablo groeber and the expanding earth

The Groeber’s vision on “The Expanding Earth” is presented based on his pioneering work published in the late 50’s. This essay provides an explanation of various mechanisms and phenomena that would act on planet Earth, such as its expansion over time and the development of convective currents explai...
