Supermassive galactic centre with repulsive gravity
Trevor W. Marshall, Max K. Wallis
Repulsive gravity has its origin in the 1939 article of Oppenheimer and Snyder which describes a collapsar, that is an idealized star of non-interacting material (dust) collapsing…
Fields tell matter how to move
Trevor W. Marshall
Starting from the Oppenheimer-Snyder solution for gravitational collapse, we show by putting it into the harmonic coordinates, for which the distant Riemann metric is galilean, tha…
Signal delay analysis for binary pulsars
Trevor W. Marshall
This note gives a correction to the standard analysis of the delay pattern in the radio signals from a pulsar in a binary system; the same coordinate frame should be used for the t…
The gravitational collapse of a dust ball
Trevor W. Marshall
It is shown that the description of collapse given by the classic model of Oppenheimer and Snyder fails to satisfy a crucial matching condition at the surface of the ball. After co…
A classical model for a photodetector in the presence of electromagnetic vacuum fluctuations
Trevor W. Marshall, Emilio Santos
The main argument against the reality of the electromagnetic vacuum fluctuations is that they do not activate photon detectors. In order to meet this objection we propose a classic…
Gravitational waves versus black holes
Trevor W. Marshall
It is argued that, in order for the gravitational field to be propagated as a wave, it is necessary for it to satisfy a further set of field equations, in addition to those of Eins…
