ABSTRACT

A revaluation of the important of the climatic variations on the Earth in the last 120,000 years
(Quaternary palaeoclimatological data) led us to render evident a special geodynamic moment
around 40,000-39,000 years (ka) before present (BP). We have correlated this moment with a
severe change of the precessional year duration caused by a modification of the rotational axis
position under the influence of a cosmic body. We consider this cosmic event to be the capture of
the Moon (by the Earth), former first planet of the Solar System. This confirms Urey’s hypothesis
about the capture of the Moon in a recent geological epoch and the mythical traditions from
ancient times about the appearance of the Moon in the sky as well. The possible deglaciation of
the northern lands at 40 ka BP discovered by Scandinavian scientists can be explained through the
same phenomenon which implies a change in the latitude. Also, at 40 ka BP, the archaeological
perspective shows a crisis in the prehistoric human populations. All these made us embrace the
hypothesis on the planetary origin of the Moon, taking into account the geochemical data from the
Selenian samples which seem to exclude the terrestrial origin of our satellite. Accepting the
capture as a natural phenomenon inside the Solar System makes us imagine the existence in the
past of a series of outer telluric planets – with Pluto and its moon, Charon, as the last survivors –
which were “decimated” through the capture by the gas giants. A dark vision of the future shows
us all the telluric planets of the Solar System (Terra inclusively) transformed in satellites of the
same giant planets.
