Why the astrophysical black hole candidates may not be black holes at all Abhas Mitra
In a recent paper[1], it has been shown that, there cannot be any rotating (Kerr) Black Hole (BH) with finite mass in order that the generic properties associated with the symmetries of stationary axisymmetric Einstein equations are obeyed, i.e, in order to have m ≥ 0, we must have a = 0. In other words, all observed chargeless BHs with finite masses must be non-rotating Schwarzschild BHs. Here...
متن کاملOn “many black hole” vacuum space-times
We analyze the horizon structure of families of space times obtained by evolving initial data sets containing apparent horizons with several connected components. We show that under certain smallness conditions the outermost apparent horizons will also have several connected components. We further show that, again under a smallness condition, the maximal globally hyperbolic development of the m...
متن کاملConstraints on mass ejection in black hole formation derived from black hole X-ray binaries
Both the recently observed high runaway velocities of Cyg X-1 (∼ 50 km s) and X-ray Nova Sco 1994 (≥ 100 km s) and the relatively low radial velocities of the black hole X-ray binaries with low mass donor stars, can be explained by symmetric mass ejection in the supernovae (SNe) which formed the black holes in these systems. Assuming symmetric mass ejection in black hole formation, we estimate ...
متن کاملThe First Law of Black Hole Mechanics
A simple proof of a strengthened form of the first law of black hole mechanics is presented. The proof is based directly upon the Hamiltonian formulation of general relativity, and it shows that the the first law variational formula holds for arbitrary nonsingular, asymptotically flat perturbations of a stationary, axisymmetric black hole, not merely for perturbations to other stationary, axisy...
متن کاملOrganizational Black Hole Theory
There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
