General topics include basic principles of atomic physics, including nuclear systematics decay modes of radionuclides, radioactive decay and geochronometry
, radiogenic isotope geochronometers, including a complete range of methods, the geochemistry of radiogenic isotopes, including igneous rocks, water, and sediment, and the oceans, short-lived radionuclides, and fractionation of stable isotopes.
Therefore, one can say that there is a direct proportionality between the spacevelocity expansion of, let say, Virgo galaxy and the Earth geochronometry. Table 1 displays the calculation of the Earth's radial expansion using the formula represented above :
Furthermore, the Earth geochronometry data may enable us to verify the cosmological theories with unprecedented precision.
