Gravitazione idrodinamica: suo legame con l’espansione dei corpi celesti e con i redshifts – Dalla storia all’oggi

Abstract

The concept of central flow of aether has antique origins that can be found in Isaac Newton (1643-1727) and less vaguely in John Bernoulli (1667-1748). From Earth Sciences come clues on an important role of the aether in the geological evolution of Earth and planets, as well as of the universe. Paleogeography allows a rough evaluation of the new ordinary matter that is added to the planet in the unity of time, and consequent cosmological consequences and inferences on the Earth inner energy balance. With the help of modern astrophysical phenomena the aether’s density, flow rate, and velocity can be computed. An intimal interrelation of these aether parameters with the actually known cosmological parameters (H0, G, c) is found. The expansion of the celestial bodies is linked to a revision of the concepts of physics and cosmology, in which a role play the preferred conception of Hubble and several of his colleagues of the time (Kragh 2017) in explaining the cosmological redshift: the idea of “tired light”.
