Zero Energy Configurations in General Relativity

چکیده
We investigate the ratio of gravitational binding energy to rest mass in general relativity. For N pointlike masses, an upper bound on the magnitude of this ratio can be derived using the second law of black hole dynamics. Only as N approaches infinity can it approach one. A configuration that saturates the N = ∞ bound is a thin spherical shell as its radius is taken to zero. This system provides, in principle, a perfectly efficient mechanism for converting rest mass into energy. We mention possible implications for the black hole information problem.

متن کاملVacuum Energy and Universe in Special Relativity
The problem of cosmological constant and vacuum energy is usually thought of as the subject of general relativity. However, the vacuum energy is important for the Universe even in the absence of gravity , i.e. in the case when the Newton constant G is exactly zero, G = 0. We discuss the response of the vacuum energy to the perturbations of the quantum vacuum in special relativity, and find that...
متن کاملBulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity
In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملCosmic Acceleration, Dark Energy, and Fundamental Physics
A web of interlocking observations has established that the expansion of the Universe is speeding up and not slowing, revealing the presence of some form of repulsive gravity. Within the context of general relativity the cause of cosmic acceleration is a highly elastic (p " #!), very smooth form of energy called ‘‘dark energy’’ accounting for about 75% of the Universe. The ‘‘simplest’’ explanat...
متن کاملGalactic dark matter halo made of spin-zero bosons
Scalar Field Dark Matter models, in which the dark matter particle is a spin-0 boson, are becoming a serious alternative to the Cold Dark Matter paradigm. In the present work, we have constructed gravitational-bounded configurations made of massive spin zero bosons that can be used as models for galactic dark matter halos. These configurations are constructed in the context of Einstein’s Genera...
