Monopole gravitational waves from relativistic fireballs driving gamma-ray bursts
Einstein’s General Relativity predicts that pressure, in general stresses, play a similar role to energy density, ǫ = ρc (with ρ being corresponding mass density), in generating gravity. The source of gravitational field, the active gravitational mass density, sometimes referred to as Whittaker’s mass density, is ρgrav = ρ + 3p/c , where p is pressure in the case of an ideal fluid. Whittaker’s ...
متن کاملImplosion of quadrupole gravitational waves
Einstein’s vacuum equations are solved up to the second approximation for imploding quadrupole gravitational waves. The implosion generates a black hole singularity irrespective of the strength of the waves.
متن کاملGravitational waves versus black holes
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 Einstein and Hilbert, and these equations mean there is a preferred coordinate frame, called the Global Inertial Frame, giving rise to a unique metric . The implication is that a true gravitational field is not compatible...
متن کاملGravitational wave astronomy - astronomy of the 21st century
An enigmatic prediction of Einstein’s general theory of relativity are gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein’s theory the existence of gravitational waves was firmly established. Currently there is a worldwide effort to detect gravitational waves with...
متن کاملGravitational Waves: An Introduction
In this article, I present an elementary introduction to the theory of gravitational waves. This article is meant for students who have had an exposure to general relativity, but, results from general relativity used in the main discussion has been derived and discussed in the appendices. The weak gravitational field approximation is first considered and the linearized Einstein’s equations are ...
