The gravitational waves are fictitious entities - III

Only Levi-Civita's electromagnetic interpretation of the characteristic hypersurfaces of Einstein field equations is conceptually correct.Comment: 7 pages, PDF from MS-Word9

Stresses, energy flow and energy density of gravitational nature

Two arguments which show the validity of the concept of gravitational energy put forward by Lorentz and Levi-Civita.Comment: 5 pages, PD

Relativity and wavy motions

The conditions under which the undulatory character of field disturbances is physically significant.Comment: 9 pages, LaTeX, to be published on Spacetime & Substanc

On Kerr's corpuscle

Simple changes of the radial co-ordinate deprive Kerr's spinning corpuscle of its marvellous properties.Comment: 4 pages, PDF from MS-Word97, submitted to Il Nuovo Cimento, Section B, pag.1 first row after eq.(1): replaced "a and r are nonnegative parameters" with "a and M are nonnegative parameters

Relativistic motions

A physical consequence of a well-known Fermi's theorem: no motion of masses can generate gravitational waves.Comment: 2 pages, PD

Non-existence of gravitational waves. The stages of the theoretical discovery (1917-2003)

A short history of the theoretical discovery that the gravitational waves of general relativity do not have a physical reality.Comment: 5 pages, LaTeX, added a parergon on PSR 1913+1

The black holes are fictive objects

We prove that the anomalous form of Schwarzschild metric within the spatial domain bounded by Schwarzschild pseudosingular surface is a mathematical mishap, devoid of any physical meaning. As a special consequence, the portions of geodesics internal to the above domain are not physically interpretable. Accordingly, the theoretical notion of black hole describes only a fictive object.Comment: 10 pages, PDF from MS-Word 7.0; added a parergon with another argument against the existence of the black hole

On continued gravitational collapse

According to a widespread idee fixe, the spherically-symmetric collapse of a sufficiently massive celestial body of spherical shape should generate a black hole. I prove that this process generates simply an ordinary point mass. My argument is model-independent.Comment: 5 pages, PDF, submitted to Il Nuovo Ciment

Gravitational waves and ether's wind

A very recent research validates observationally the theoretical demonstrations of the physical non-existence of the gravitational waves.Comment: 2 pages, LaTeX, submitted to Il Nuovo Saggiator

Relativistic spherical symmetries

The observational "black holes" are quite different objects from the theoretical black holes.Comment: 7 pages, PD
